3 physicists share Nobel Prize for work on quantum science

Published

7 minute read

STOCKHOLM (AP) — Three scientists jointly won this year’s Nobel Prize in physics on Tuesday for their work on quantum information science that has significant applications, for example in the field of encryption.

Frenchman Alain Aspect, American John F. Clauser and Austrian Anton Zeilinger were cited by the Royal Swedish Academy of Sciences for discovering the way that unseen particles, such as photons or tiny bits of matter, can be linked, or “entangled,” with each other even when they are separated by large distances.

“Being a little bit entangled is sort of like being a little bit pregnant. The effect grows on you,” Clauser said in a Tuesday morning phone interview with The Associated Press.

It all goes back to a feature of the universe that even baffled Albert Einstein and connects matter and light in a tangled, chaotic way.

Clauser, 79, was awarded his prize for a 1972 experiment that helped settle a famous debate about quantum mechanics between Einstein and famed physicist Niels Bohr. Einstein described “a spooky action at a distance” that he thought would eventually be disproved.

“I was betting on Einstein,” Clauser said. “But unfortunately I was wrong and Einstein was wrong and Bohr was right.”

Clauser said his work on quantum mechanics shows that you can’t confine information to a closed volume, “like a little box that sits on your desk” — though even he can’t say why.

“Most people would assume that nature is made out of stuff distributed throughout space and time,” Clauser said. “And that appears not to be the case.”

Quantum entanglement “has to do with taking these two photons and then measuring one over here and knowing immediately something about the other one over here,” said David Haviland, chair of the Nobel Committee for Physics. “And if we have this property of entanglement between the two photons, we can establish a common information between two different observers of these quantum objects. And this allows us to do things like secret communication, in ways which weren’t possible to do before.”

That’s why quantum information is not an esoteric thought experiment, said Eva Olsson, a member of the Nobel committee. She called it a “vibrant and developing field.”

“It has broad and potential implications in areas such as secure information transfer, quantum computing and sensing technology,” Olsson said. “Its predictions have opened doors to another world, and it has also shaken the very foundations of how we interpret measurements.”

Everything in the universe could be entangled but “usually the entanglement just kind of washes off. It’s so chaotic and random that when you look at it … we don’t see anything,” said Harvard professor Subir Sachdev, who has worked on experiments that look at quantum entangled material consisting of up to 200 atoms. But sometimes scientists can unsnarl just enough to make sense and be useful in everything from encryption to superconductors, he said.

Speaking by phone to a news conference after the announcement, Zeilinger said he was “still kind of shocked” at hearing he had received the award.

“But it’s a very positive shock,” said Zeilinger, 77, who is based at the University of Vienna.

Clauser, Aspect, and Zeilinger have figured in Nobel speculation for more than a decade. In 2010 they won the Wolf Prize in Israel, seen as a possible precursor to the Nobel.

While physicists often tackle problems that appear at first glance to be far removed from everyday concerns — tiny particles and the vast mysteries of space and time — their research provides the foundations for many practical applications of science.

The Nobel committee said Clauser developed quantum theories first put forward in the 1960s into a practical experiment. Aspect, 75, was able to close a loophole in those theories, while Zeilinger demonstrated a phenomenon called quantum teleportation that effectively allows information to be transmitted over distances.

“Using entanglement you can transfer all the information which is carried by an object over to some other place where the object is, so to speak, reconstituted,” said Zeilinger. He added that this only works for tiny particles.

“It is not like in the Star Trek films (where one is) transporting something, certainly not the person, over some distance,” he said.

When he began his research, Zeilinger said the experiments were “completely philosophical without any possible use or application.”

Since then, the laureates’ work has been used to develop the fields of quantum computers, quantum networks and secure quantum encrypted communication.

A week of Nobel Prize announcements kicked off Monday with Swedish scientist Svante Paabo receiving the award in medicine Monday for unlocking secrets of Neanderthal DNA that provided key insights into our immune system.

They continue with chemistry on Wednesday and literature on Thursday. The 2022 Nobel Peace Prize will be announced on Friday and the economics award on Oct. 10.

The prizes carry a cash award of 10 million Swedish kronor (nearly $900,000) and will be handed out on Dec. 10. The money comes from a bequest left by the prize’s creator, Swedish inventor Alfred Nobel, who died in 1895.

Iran government supporters confront protesters at World Cup

Published on

AL RAYYAN, Qatar (AP) — Tensions ran high at Iran’s second match at the World Cup on Friday as fans supporting the Iranian government harassed those protesting against it and stadium security seized flags, T-shirts and other items expressing support for the protest movement that has gripped the Islamic Republic.

Some fans were stopped by stadium security from bringing in Persian pre-revolutionary flags to the match against Wales at the Ahmad Bin Ali Stadium. Others carrying such flags had them ripped from their hands by pro-government Iran fans, who also shouted insults at fans wearing T-shirts with the slogan of the protest movement gripping the country, “Woman, Life, Freedom.”

Unlike in their first match against England, the Iran players sang along to their national anthem before the match as some fans in the stadium wept, whistled and booed.

The national team has come under close scrutiny for any statements or gestures about the nationwide protests that have wracked Iran for weeks.

Shouting matches erupted in lines outside the stadium between fans screaming “Women, Life, Freedom” and others shouting back “The Islamic Republic!”

Mobs of men surrounded three different women giving interviews about the protests to foreign media outside the stadium, disrupting broadcasts as they angrily chanted, “The Islamic Republic of Iran!” Many female fans appeared shaken as Iranian government supporters shouted at them in Farsi and filmed them up close on their phones.

After Iran’s 2-0 triumph, crowds of Iranian fans wildly waving national flags streamed out of the stadium. They thronged a group of protesters who held up photos of Mahsa Amini, the 22-year-old whose Sept. 16 death in the custody of the morality police first unleashed the protests, yelling “Victory!” to drown out chants of Amini’s name.

One 35-year-old woman named Maryam, who like other Iran fans declined to give her last name for fear of government reprisals, started to cry as shouting men blowing horns encircled her and filmed her face. She had the words “Woman Life Freedom” painted on her face.

“We want to raise awareness about his arrest and about the women’s rights movement,” said Maryam, who lives in London but is originally from Tehran. “I’m not here to fight with anyone, but people have been attacking me and calling me a terrorist. All I’m here to say is that football doesn’t matter if people are getting killed in the streets.”

Maryam and her friends had worn hats emblazoned with the name of an outspoken Iranian former soccer player Voria Ghafouri, who had criticized Iranian authorities and was arrested in Iran on Thursday on accusations of spreading propaganda against the government. She said Iranian government supporters had taken the hats from their heads.

Ghafouri, who is Kurdish, was a star member of Iran’s 2018 World Cup team, but was surprisingly not named in the squad for this year in Qatar.

“It’s obvious that the match had become very politicized this week. You can see people from the same country who hate each other,” said Mustafa, a 40-year-old Iran fan who also declined to give his last name. “I think the arrest of Voria has also affected society in Iran a lot.”

Furious protesters in Iran have been venting their anger over social and political repression and the state-mandated headscarf, or hijab, for women. The demonstrations have quickly grown into calls for the downfall of the Islamic Republic itself. At least 419 people have been killed since the protests erupted, according to monitoring group Human Rights Activists in Iran.

The turmoil has overshadowed the start of Iran’s World Cup campaign. The opening match against England on Monday was the scene of protests as anti-government fans waved signs and chanted in the stands. Before that match, which Iran lost 6-2, its players remained silent as their national anthem played and didn’t celebrate their two goals. On Friday, they sang along to the anthem and celebrated wildly when they scored twice against Wales.

Ayeh Shams, an Iranian from the United States, said security guards confiscated her flag because it had the word “women” written on it.

“We’re just here to enjoy the games and give a platform for the Iranian people who are fighting against the Islamic regime,” Shams said.

Zeinlabda Arwa, a security guard at the stadium, confirmed that authorities had been given orders to confiscate anything but the flag of the Islamic Republic of Iran.

“Whether you’re talking about Iran or Qatar or any country, you are only allowed to bring in the normal flag,” she said.

An angry group of Iranian government supporters shouted at Elyas Doerr, a 16-year-old Iranian boy living in Arizona who was wearing the Persian flag as a cape, until he took it off and and put it in his bag.

“They’re not liking that it’s a political statement,” he said, adding that other Iranian fans had approached him to say they appreciated the gesture.

A 32-year-old Iranian woman living in southern Spain, who declined to give her name for fear of reprisals, scrambled after the match to retrieve her hat and flag that had been confiscated by stadium security. She said Qatari police ordered her to scrub off the names of Iranian protesters killed and arrested by security forces that she had written on her arms and chest, at the behest of Iranian government supporters. At the game, just traces of ink remained on her skin that was rubbed raw.

“Today’s football experience was the most intimidating I’ve ever been in, before and after the match,” she said. She described dozens of men who surrounded her and tried to smother her face with their Iranian flags, snatching her signs as Qatari security stood by.

“I don’t care about the win, to be honest. That’s not my priority.”

After the game, Iranian state television broadcast patriotic songs and showed footage of people bursting out into cheers across the country.

Sajjan mum on human rights during World Cup visit to Qatar

Published on

By Dylan Robertson in Ottawa

OTTAWA — International Development Minister Harjit Sajjan is facing opposition criticism because he did not make a public statement about human rights during his visit to Qatar for the World Cup.

“If we don’t raise the issue of human rights when we are in countries where we know human rights abuses are taking place, we have no moral authority,” said NDP foreign-affairs critic Heather McPherson.

Sajjan attended the World Cup on behalf of the Trudeau government, where the Canadian men’s team is competing for the first time in years. He met with U.S. Secretary of State Antony Blinken and local officials.

Yet Sajjan’s social media postings make no mention of the host country’s documented mistreatment of migrant workers, nor the emirate’s anti-LGBTQ policies.

Those concerns have led some broadcasters and players to sport armbands that say “One Love.” The German team covered their mouths when their official photo was taken.

Sajjan’s office said he was unavailable Thursday for comment as he was flying back to Canada.

Labour Minister Seamus O’Regan, who is gay, said he felt split on Qatar’s hosting.

“I’ll be honest, it’s very conflicting. I’m cheering on my team; I’m cheering on my country and (want) nothing but the best. But I’ll tell, you it’s kind of difficult,” he said

O’Regan said he could not speak for Sajjan, but noted the government voiced concerns about Qatar before the games got underway.

“We know exactly where we stand on it; we’ve voiced our displeasure clearly,” he said.

The NDP had called for a diplomatic boycott of the tournament.

“This is talking out of both sides of your mouth, with this government,” McPherson said.

“This government once again has shown that they don’t really care about human rights.”

On Monday, MPs passed a unanimous motion condemning FIFA for threatening to penalize players who wore the “One Love” armbands. The motion argued that “international sporting governing bodies have a moral obligation to support players and fans in highlighting the fight for equality against homophobia, transphobia, and all forms of discrimination in sport.”

Captains of several European countries scrapped plans to wear a “One Love” armband after FIFA, soccer’s governing body, warned they would face on-field sanctions.

Media reports from Qatar also said some fans wearing rainbow attire were refused entry to the stadiums.

This month, Amnesty International rebuked Soccer Canada for its “deafening silence” on the thousands of workers, predominantly from South Asia, Southeast Asia and Africa, who “have been subjected to labour abuses, abysmally low pay, and other exploitation.”

Soccer Canada released a statement last month in support of ongoing reforms, but steered clear of criticizing the emirate.

Amnesty noted that peer federations from Britain, the U.S., France and the Netherlands all endorsed calls for a compensation fund for migrant workers who were mistreated while preparing Qatar for the games.

The Conservatives did not have a direct comment on Sajjan’s actions. Instead, MP Michael Chong said his party prefers that the World Cup be hosted by countries with better reputations, such as a bid by Ukraine to co-host the 2030 tournament with Spain and Portugal.

“Conservatives condemn in the strongest terms all human rights abuses around the world and are prepared to work with our democratic allies to support human rights,” Chong wrote in a statement.

The Bloc Québécois had also called for a diplomatic boycott, and lamented Sajjan’s attendance in Qatar. “Canada has no excuse to turn a blind eye to human rights abuses,” MP Martin Champoux tweeted in French on Monday.

During the 2008 Olympic Games in Beijing, the Liberals urged the Harper government to raise the issue of human rights in China.
