STOCKHOLM – US-based scientists John Clarke, Michel Devoret and John Martinis won the 2025 Nobel Prize in Physics for “experiments that revealed quantum physics in action”, paving the way for the development of the next generation of digital technologies.

“My feelings are that I’m completely stunned. Of course it had never occurred to me in any way that this might be the basis of a Nobel Prize,” Clarke told the Nobel press conference by telephone on Tuesday.

“I’m speaking on my cell phone and I suspect that you are too, and one of the underlying reasons that the cell phone works is because of all this work.”

‘NEW SURPRISES’ IN CENTURY-OLD FIELD OF QUANTUM MECHANICS
Quantum mechanical behaviors are well studied at the level of the incredibly small – atoms and sub-atomic particles – but are often seen as bizarre and unintuitive compared with classical physics and its far larger scale.

The Nobel winners carried out experiments in the mid-1980s with an electronic circuit built of superconductors and demonstrated that quantum mechanics could also influence everyday objects under certain conditions.

“It is wonderful to be able to celebrate the way that century-old quantum mechanics continually offers new surprises. It is also enormously useful, as quantum mechanics is the foundation of all digital technology,” Olle Eriksson, chair of the Nobel Committee for Physics, said.

Quantum technology is already ubiquitous, with transistors in computer microchips an everyday example.

“This year’s Nobel Prize in Physics has provided opportunities for developing the next generation of quantum technology, including quantum cryptography, quantum computers, and quantum sensors,” the Royal Swedish Academy of Sciences, which awards the prize, said in a statement.

Quantum computers use principles of quantum mechanics to make complex calculations, predict outcomes and perform analysis that in some cases could take traditional computers millions of years.

The field is considered to have the potential to help solve some of humanity’s most pressing concerns, such as tackling climate change. But it also faces challenges, including improving the accuracy of its chips, and timelines for commercially viable quantum computing remain disputed.

TWO OF WINNING TRIO HAVE LINKS TO GOOGLE
British-born Clarke is a professor at the University of California, Berkeley, in the United States.

Devoret, who was born in France and was congratulated on X by French President Emmanuel Macron, is a professor at Yale University and the University of California, Santa Barbara, also in the United States, where Martinis is also a professor.

Martinis, an American, headed Google’s Quantum Artificial Intelligence Lab until 2020. At Google, Martinis was part of the research team who in 2019 said they had achieved “quantum supremacy”, in which a computer harnessing the properties of sub-atomic particles did a far better job of solving a problem than the world’s most powerful supercomputer.

Devoret, besides his professorship, is also the chief scientist of Google Quantum AI. It is the second straight year that a Nobel has been won by scientists with Google ties. The 2024 chemistry prize was awarded to Demis Hassabis and John Jumper at Google DeepMind while Geoffrey Hinton, who worked for Google for more than a decade, won for physics the same year.

PHYSICS SECOND NOBEL PRIZE AWARDED THIS WEEK
The Nobel physics prize is awarded by the Royal Swedish Academy of Sciences and includes a prize sum totalling 11 million Swedish crowns ($1.2 million) that is shared among the winners if there are several, as is often the case.

The Nobel Prizes were established through the will of Alfred Nobel, who amassed a fortune from his invention of dynamite. Since 1901, with occasional interruptions, the prizes have annually recognised achievements in science, literature, and peace. Economics was a later addition.

Physics was the first category mentioned in Nobel’s will, likely reflecting the prominence of the field during his time. Today, the Nobel Prize in Physics remains widely regarded as the most prestigious award in the discipline.

Past winners of the Nobel physics prize include some of the most influential figures in the history of science, such as Albert Einstein, Erwin Schrodinger, Max Planck and Niels Bohr, the latter three all pioneers of quantum theory.

In keeping with tradition, physics is the second Nobel to be awarded this week, after two American and one Japanese scientist won the medicine prize for breakthroughs in understanding the immune system. The chemistry prize is due next, on Wednesday.

The science, literature and economics prizes are presented to the laureates by the Swedish king at a ceremony in Stockholm on December 10, the anniversary of Alfred Nobel’s death, followed by a lavish banquet at city hall.

The peace prize, which will be announced on Friday, is awarded in a separate ceremony in Oslo. — Reuters

WASHINGTON – Air traffic control staffing issues are delaying flights for a second straight day at numerous US airports as the government shutdown reaches its seventh day, the Federal Aviation Administration said in a notice on Tuesday.

More than 3,000 flights have been delayed, according to flight tracking data, as staffing shortages have impacted a widening number of airports, including Houston, Nashville, Dallas, Chicago O’Hare and Newark.

The FAA is reducing the number of arriving flights per hour at Chicago O’Hare, citing staffing, with average delays of 41 minutes, and there are also staffing issues at Atlanta Air Route Traffic Control Center.

Arriving flights were being held for up to 30 minutes at Newark due to the staffing issues, the FAA said, while Washington Reagan might see new slowdowns due to low staffing on Tuesday.

Nashville air traffic control is facing significant staffing issues and will curtail operations later on Tuesday, the FAA said. Approach control will be taken over later by Memphis Center, it added.

Both political parties are pointing the finger at each other for the impacts. White House press secretary Karoline Leavitt said Democrats were to blame for the aviation slowdown, while California Governor Gavin Newsom, a Democrat, said President Donald Trump was responsible.

Severe weather is also impacting flights across the country.

Some 13,000 air traffic controllers and about 50,000 Transportation Security Administration officers must still turn up for work during the government shutdown, but they are not being paid. Controllers are set to receive a partial paycheck on October 14 for work performed before the shutdown.

Transportation Secretary Sean Duffy said on Monday the FAA had seen a slight increase in controllers taking sick leave and air traffic staffing has been cut by 50% in some areas since the shutdown started last week.

“If we don’t have controllers, we’re going to make sure the airspace is safe. So what we do is we’ll slow traffic,” Duffy said on Tuesday on Fox News’ “Fox and Friends.”

FlightAware, a flight tracking website, said more than 3,000 US flights had been delayed on Tuesday, including 225 at Nashville, or 20% of its flights, and more than 570 flights at Chicago O’Hare, or more than 20% of its flights.

Southwest Airlines has delayed more than 500 flights and American Airlines 400 flights, FlightAware data showed.

In 2019, during a 35-day shutdown, the number of absences by controllers and TSA officers rose as workers missed paychecks, extending checkpoint wait times at some airports. Authorities were forced to slow air traffic in New York, which put pressure on lawmakers to quickly end the standoff.

The US has faced air traffic control shortages for more than a decade, and many controllers had been working mandatory overtime and six-day weeks even before the shutdown. The FAA is about 3,500 air traffic controllers short of targeted staffing levels. — Reuters

SHARM EL-SHEIKH, Egypt – Hamas said on Tuesday it was ready to reach a deal to end the war in Gaza based on President Donald Trump’s plan but still has demands, as Qatar’s prime minister and senior US mediators headed to Egypt to join indirect negotiations between the Palestinian militant group and Israel.

On the second anniversary of Hamas’ attack on Israel that triggered the Gaza war, Trump expressed optimism about progress toward a Gaza deal. A US team including special envoy Steve Witkoff and Jared Kushner, Trump’s son-in-law and his Middle East envoy during his first term, left for the talks.

“I think there’s a possibility that we could have peace in the Middle East” beyond just Gaza, the US president told reporters in the Oval Office.

A source close to the talks said they had adjourned for the day and the atmosphere had been better than on Monday. Negotiations on Wednesday would be a decisive indicator of whether progress was possible given the presence of the senior mediators, the source said.

Prime Minister Sheikh Mohammed bin Abdulrahman al-Thani of Qatar, which has been one of the key mediators, will join the talks on Wednesday, an official told Reuters, “with the aim of pushing forward the Gaza ceasefire plan and hostage release agreement”.

On the second day of talks in the Egyptian resort of Sharm el-Sheikh, top Hamas leader Khalil Al-Hayya told Egyptian state-affiliated Al Qahera News TV the group had come “to engage in serious and responsible negotiations.”

He said Hamas was ready to reach a deal, yet it needed a “guarantee” to end the war and ensure “it is not repeated”.

According to Gaza authorities, some 67,000 people have been killed and Gaza devastated since the October 7, 2023 attack by Palestinian militants on Israel. Israel says 1,200 people were killed and 251 were taken back to Gaza as hostages on that day.

The talks appeared to hold the most promise yet of ending the war. But officials on all sides urged caution over the prospects for a rapid agreement, as Israelis remembered the bloodiest single day for Jews since the Holocaust and Gazans voiced hope for an end to the suffering brought by the war.

Even if a deal is clinched, questions will linger over who will govern Gaza and rebuild it, and who will finance the huge cost of reconstruction. Trump and Israeli Prime Minister Benjamin Netanyahu have ruled out any role for Hamas.

HAMAS SETS OUT CONDITIONS
Trump met Witkoff and Kushner, who will join the talks on Wednesday, for an update on the negotiations before they departed for Egypt, a senior US official said. They discussed issues such as ensuring the safety of the hostages and security guarantees, the official added.

“The (Hamas) movement’s delegation participating in the current negotiations in Egypt is working to overcome all obstacles to reaching an agreement that meets the aspirations of our people in Gaza,” senior Hamas official Fawzi Barhoum said in a televised statement.
He said a deal must ensure an end to the war and a full Israeli withdrawal from the Gaza Strip – conditions that Israel has never accepted. Israel, for its part, wants Hamas to disarm, something the group rejects.

Hamas wants a permanent, comprehensive ceasefire, a complete pullout of Israeli forces and the immediate start of a comprehensive reconstruction process under the supervision of a Palestinian “national technocratic body”, he said.

Underlining the obstacles at talks, an umbrella of Palestinian factions including Hamas issued a statement vowing a “resistance stance by all means” and saying “no one has the right to cede the weapons of the Palestinian people”.

Netanyahu did not immediately comment on the status of the talks. But in a statement on X, he told Israelis they were in “fateful days of decision.”

“We will continue to act to achieve all the war’s objectives: the return of all the hostages, the elimination of Hamas’s rule, and the assurance that Gaza will no longer pose a threat to Israel,” he said.

US officials have suggested they want to initially focus talks on a halt to the fighting and the logistics of how the hostages and Palestinian prisoners in Israel would be freed.
In the absence of a ceasefire, Israel has pressed on with its offensive in Gaza, which has increased its international isolation.

Opponents of Israel’s actions in Gaza held protests in Sydney, Australia and a handful of European cities on the anniversary of Hamas’ attack, despite denunciations by some politicians who said such marches risked glorifying violence.

HOPES OF A BREAKTHROUGH BY CIVILIANS ON BOTH SIDES
On the anniversary, some Israelis visited the places that were hit hardest that day.

Orit Baron stood at the site of the Nova music festival in southern Israel beside a photo of her daughter Yuval, who was killed with her fiance Moshe Shuva. They were among 364 people who were shot, bludgeoned or burned to death there.

“They were supposed to get married on February 14th, Valentine’s Day,” said Baron. “They are buried next to each other because they were never separated.”

Israelis are hoping the talks will soon lead to the release of the 48 hostages still held in Gaza, 20 of whom are believed to still be alive.

“It’s like an open wound, the hostages, I can’t believe it’s been two years and they are still not home,” said Hilda Weisthal, 43.

In Gaza, 49-year-old Palestinian Mohammed Dib hoped for the end of a conflict that has caused a humanitarian disaster and displaced many Palestinians multiple times.

“It’s been two years that we are living in fear, horror, displacement and destruction,” he said.– Reuters
