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 behaviours 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.

White House says Trump MRI was preventative, president in excellent health

White House says Trump MRI was preventative, president in excellent health

WASHINGTON: The White House has said that President Donald Trump is in good health, even as people continue to question how his age may affect his performance as the country’s most powerful man. 

White House press secretary Karoline Leavitt said on Monday that a recent MRI conducted on President Trump was preventative in nature and revealed that he was in good cardiovascular health.

Speaking to reporters at a press briefing at the White House, Leavitt said men of Trump’s age benefited from such screenings.

‘President Trump’s cardiovascular imaging was perfectly normal, no evidence of arterial narrowing, impairing blood flow or abnormalities in the heart or major vessels,’ Leavitt said of the 79-year-old president.

‘The heart chambers are normal in size. The vessel walls appear smooth and healthy, and there are no signs of inflammation or clotting. Overall, his cardiovascular system shows excellent health. His abdominal imaging is also perfectly normal,’ Leavitt said.

Trump underwent a magnetic resonance imaging scan during a recent medical evaluation, but did not disclose the purpose of the procedure, which is not typical for standard check-ups. The lack of details raised questions about whether full information regarding the president’s health is being released in a timely fashion by the White House.

Trump is sensitive about his age and well-being. He personally attacked a female New York Times reporter on social media last week over a story she co-wrote examining the ways that Trump’s age may be affecting his energy levels.

Tajikistan says five Chinese nationals killed in cross-border attacks from Afghanistan in past week

Tajikistan says five Chinese nationals killed in cross-border attacks from Afghanistan in past week



Five Chinese nationals have been killed and five more injured in Tajikistan in attacks launched from neighbouring Afghanistan over the past week, Tajik authorities and China’s embassy in the Central Asian country said on Monday.

China’s embassy in Dushanbe, the capital, advised Chinese companies and personnel to urgently evacuate the border area.

It said that Chinese citizens had been targeted in an armed attack close to the Afghan border on Sunday. On Friday, it said that another border attack — which Tajik authorities said had involved drones dropping grenades — had killed three Chinese citizens.

Tajikistan, a mountainous former Soviet republic of around 11 million people with a secular government, has tense relations with the Taliban authorities in Afghanistan. It has previously warned of drug smugglers and illicit gold miners working along the remote frontier.

China, which also has a remote, mountainous border with Tajikistan, is a major investor in the country.

There was no immediate response on Monday from the authorities in Afghanistan to the Tajik statement.

But Afghanistan’s foreign ministry last week blamed an unnamed group, which it said was out to create instability, and said it would cooperate with Tajik authorities.

Tajik President Emomali Rahmon’s press service said on Monday that Rahmon had met with the heads of his security agencies to discuss how to strengthen border security.

It said that Rahmon “strongly condemned the illegal and provocative actions of Afghan citizens and ordered that effective measures be taken to resolve the problem and prevent a recurrence of such incidents.”

Tajikistan endured a brutal civil war in the 1990s after independence from Moscow, during which Rahmon initially rose to power. The country is closely aligned with Russia, which maintains a military base there.

Millions of Tajiks, a Persian-speaking nation, live across the border in Afghanistan, with Tajikistan historically having backed Afghan Tajiks opposed to the Taliban.
