John Clarke, Michel H. Devoret and John M. Martinis won the Nobel Prize in Physics on Tuesday for research on seemingly obscure quantum tunneling that is advancing digital technology.

Clarke, 83, conducted his research at the University of California, Berkeley; Martinis at the University of California, Santa Barbara; and Devoret at Yale and also at the University of California, Santa Barbara.

“To put it mildly, it was the surprise of my life,” Clarke told reporters at the announcement by phone after being told of his win.

He paid tribute to the other two laureates, saying that “their contributions are just overwhelming."

“Our discovery in some ways is the basis of quantum computing. Exactly at this moment where this fits in is not entirely clear to me.”

However, speaking from his cellphone, Clarke added: “One of the underlying reasons that cellphones work is because of all this work.’’

The Nobel committee said that the laureates' work in the 1980s continues to provide opportunities to develop “the next generation of quantum technology, including quantum cryptography, quantum computers, and quantum sensors.”

“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,” said Olle Eriksson, Chair of the Nobel Committee for Physics.

The 100-year-old field of quantum mechanics deals with the seemingly impossible subatomic world where switches can be on and off at the same time and parts of atoms tunnel through what seems like impenetrable barriers. The prize-winning trio’s work helped take that into the larger world, where it has the potential to supercharge computing and communications.

What the three physicists did “is taking the scale of something that we can’t see, we can’t touch, we can’t feel and bringing it up to the scale of something recognizable and make it something you can build upon,” said Physics Today editor-in-chief Richard Fitzgerald, who in the 1990s worked in the field on a competitors’ group.

“Quantum computers is one very sort of obvious use, but they’re also can be used for quantum sensors, so to be able to make very sensitive measurements of, for example, magnetic fields, and perhaps also for cryptography, so to encode information so it cannot be easily listened to by a third party,” Mark Pearce, a professor of astrophysics and Nobel Physics Committee member, told The Associated Press.

It is the 119th time the prize has been awarded. Last year, artificial intelligence pioneers John Hopfield and Geoffrey Hinton won the physics prize for helping create the building blocks of machine learning.

On Monday, Mary E. Brunkow, Fred Ramsdell and Dr. Shimon Sakaguchi won the Nobel Prize in medicine on Monday for discoveries about how the immune system knows to attack germs and not our bodies.

Nobel announcements continue with the chemistry prize on Wednesday and literature on Thursday. The Nobel Peace Prize will be announced Friday and the Nobel Memorial Prize in economics on Oct. 13.

The award ceremony will be held Dec. 10, the anniversary of the 1896 death of Alfred Nobel, the wealthy Swedish industrialist and the inventor of dynamite who founded the prizes.

The prizes carry priceless prestige and a cash award of 11 million Swedish kronor (nearly $1.2 million).

Nobel week was underway in Stockholm and Oslo with laureates holding news conferences and lectures before they will be awarded the prestigious prizes.

Hungarian László Krasznahorkai, who won the Prize in literature for his surreal and anarchic novels that combine a bleak world view with mordant humor, was expected to give a lecture in Stockholm on Sunday in one of his rare public appearances.

When the Nobel judges announced the award in October, they described the 71-year-old as “a great epic writer” whose work “is characterized by absurdism and grotesque excess.”

“Krasznahorkai’s work can be seen as part of a Central European tradition," the Nobel Prize organization said. “Important features are pessimism and apocalypse, but also humor and unpredictability."

Last year’s winner was South Korean author Han Kang. The 2023 winner was Norwegian writer Jon Fosse, whose work includes a seven-book epic made up of a single sentence.

Meanwhile, the director of the Norwegian Nobel Institute, Kristian Harpviken, said Saturday that Venezuelan Peace Prize laureate and opposition leader María Corina Machado will come to Oslo this week to receive her award in person.

The 58-year-old, who won for her struggle to achieve a democratic transition in the South American nation, has been hiding and has not been seen in public since January.

Harpviken told Norwegian public broadcaster NRK that Machado was expected to personally pick up the prize on Wednesday.

“I spoke with the Peace Prize winner last night, and she will come to Oslo,” Harpviken said, according to NRK.

Nobel Prize award ceremonies are held on Dec. 10, the anniversary of Alfred Nobel’s death in 1896. The award ceremony for peace is in Oslo and the other ceremonies are in Stockholm.

Christmas cheer returned to the traditional birthplace of Jesus Christ on Saturday as Bethlehem in the occupied West Bank lit up a tree for the first time since the war in Gaza began over two years ago.

Covered in red and gold baubles, the Christmas tree standing meters away from the Church of the Nativity on Manger Square has become a symbol of hope.

At the end of a two-hour ceremony, the tree was illuminated to cheers, its yellow lights twinkling and a bright red star on top shining against the clouded night sky irradiated by a luminescent, almost full moon.

It is the first time the city has held the usual celebrations since the outbreak of the war in Gaza following Hamas’s attack on Israel in October 2023.

“It’s like a symbol for resilience,” said 27-year-old Abeer Shtaya, who works at Al-Zaytoonah University of Science and Technology in Salfit in the West Bank.

She had traveled 100 kilometers (60 miles) with a group of the university’s students because “we want to celebrate and be with our brothers and sisters in Bethlehem to enjoy this day.”

“It’s a message for the world that it’s calm,” Mike Shahen, 43, said at his ceramic store on the square, after a handful of visitors came in for purchases.

Thousands of people attended, including Christians and Muslims, and many who traveled from Palestinian territories and Israel -- some from even further afield -- to enjoy the festive spirit return.

Nuns could be seen watching from one roof, while many families including small children filled balconies and roofs to catch a glimpse of the tree lit up.

Sounds of laughter filled the air as many could not help but smile despite moments of rain.

“This event didn’t happen for the last two years because of the war and it’s quite emotional after two years of nothing but war and death,” said 50-year-old Liyu Lu, who had traveled from northern Israel, close to the border with Lebanon.

Originally from China but now living in Israel for decades, she was with a group including Gary Lau, a traveling businessman and Christian staying in Jerusalem for the past couple of months.

“Being here, with the festivities, is something very nice and special,” Lau, 51, said, adding he was “taking in the atmosphere.”

For the past two years, Bethlehem has celebrated Christmas in a more somber manner, with no major public festivities.

Tentative return

Christian pilgrims, especially from Asia, South America and eastern Europe have, however, slowly returned in the past few months.

Fabien Safar, guide and director of Terra Dei which organizes pilgrimages to the Holy Land, said a few small groups would come for Christmas this year and he already saw some bookings for 2026.

Safar expected a real recovery in 2027 but “this obviously depends on how the situation evolves” in Gaza and Lebanon.

Despite a November 2024 ceasefire that was supposed to end more than a year of hostilities between Israel and militant group Hezbollah, Israel has kept up strikes on Lebanon.

Pilgrims “remain afraid because there’s no official end to the war” in Gaza, Safar said, adding they were also worried about the situation in Lebanon.

‘Worse than COVID’

But it has all taken a toll on Bethlehem, which had only just cheered the return of tourists in 2022 after the COVID-19 pandemic, before the war in Gaza broke out.

Bethlehem’s economy relies almost completely on tourism.

“Covid was bad but nothing like the last two years,” said Shahen from the ceramic store.

Many visitors from Israel and the Palestinian territories spent hours on the road to reach Bethlehem including musician Lu.

She woke up at 6 am to get a bus at 7 am with a large group. They arrived at 12:30 pm, she said, without any trouble.

War isn’t the only reason for Bethlehem’s woes.

Since the 2023 Hamas attack, it is more difficult to travel around the West Bank with long queues on the roads with Israeli military checkpoints.

Violence in the West Bank, which Israel has occupied since 1967, has also surged since the Gaza war. It has not stopped despite the fragile truce between Israel and Hamas that began this October.


Number's Up: Calculators Hold Out against AI

Number's Up: Calculators Hold Out against AI

The humble pocket calculator may not be able to keep up with the mathematical capabilities of new technology, but it will never hallucinate.

The device's enduring reliability equates to millions of sales each year for Japan's Casio, which is even eyeing expansion in certain regions.

Despite lightning-speed advances in artificial intelligence, chatbots still sometimes stumble on basic addition.

In contrast, "calculators always give the correct answer," Casio executive Tomoaki Sato told AFP.

But he conceded that calculators could one day go the way of the abacus.

"It's undeniable that the market for personal calculators used in business is on a downward trend," Sato said in Tokyo.

Smartphones and web browsers can handle everyday sums, while AI models achieved gold-level scores for the first time this year at a prestigious global maths contest.

But calculators are more affordable than phones, and run on batteries and solar power -- a plus for schools in developing countries, a potential growth area for Casio, Sato said.

And people who do buy calculators prefer the way they feel, he argued.

Thitinan Suntisubpool, co-owner of a shop selling red bags and beckoning cats in Bangkok's Chinatown, said she loves how durable her big calculator is, having dropped it several times.

"It's more convenient in many ways," the 58-year-old told AFP.

"We can use it to press the numbers and show the customer," avoiding language-barrier misunderstandings.

But at a nearby street stall selling clocks, torches and calculators, the vendor, who gave her name as Da, said calculator sales were "quiet".

'Optimised tools'

At a Casio factory in Thailand, assembly line workers slotted green circuit boards into place and popped cuboid buttons labelled "DEL" from a plastic tub onto pastel-blue calculator frames.

"Calculators are still in demand," said Ryohei Saito, a general manager for Casio in Thailand.

"Not everywhere in the world has smartphone connectivity, and calculators are optimised tools focused on necessary functions," he said.

In the year to March 2025, Casio sold 39 million calculators, general and scientific, in around 100 countries.

That compares to 45 million in 2019-20, but is still up from the 31 million that sold the following year after the Covid-19 pandemic hit.

The company has come a long way from the 1957 invention of the desk-sized "14-A", which it says was the first compact all-electric calculator.

Calculator history even made headlines recently when Christie's suspended the Paris sale of an early calculating machine, "La Pascaline", after a court said it could not be taken abroad.

The auction house called the ebony-decorated 1642 device "the first attempt in history to substitute the human mind with a machine".

Those attempts have accelerated with AI.

Scoring gold

In July, AI models made by Google, OpenAI and DeepSeek reached gold-level scores at the annual International Mathematical Olympiad (IMO).

But neither attained full marks at the annual contest for under-20s, unlike five human participants who achieved perfect scores.

IMO president Gregor Dolinar called the progress of artificial intelligence in the field "fascinating".

"When we talk about scientific calculators, in the past you needed them, but nowadays it's easier to just ask AI," he told AFP.

"If you pose the question in the right way," artificial intelligence can crunch abstract, logical questions and show how it reached its conclusion, Dolinar said.

Dolinar, a professor in engineering at the University of Ljubljana, thinks physical calculators are likely to "slowly disappear".

Something that has already happened for his students.

"They can calculate everything on a phone," he said.
