An Australian-led research team yesterday said it had made a technological breakthrough in the race for a quantum supercomputer that could revolutionize data encryption and medicine.
Engineers from Sydney’s University of New South Wales said they had created the first working quantum bit or qubit — the fundamental unit of a quantum supercomputer — with the findings published in the latest edition of Nature.
Lead researcher Andrew Dzurak said the team used a microwave field to gain unprecedented control over en electron bound to a single phosphorous atom that was implanted in a silicon transistor device.
They were able to both write and read information using the electron’s spin, or magnetic orientation, which Dzurak said was a “key advance towards realizing a silicon quantum computer based on single atoms.”
“This is a remarkable scientific achievement, governing nature at its most fundamental level, and has profound implications for quantum computing,” he said.
Quantum computing harnesses the power of atoms and molecules to perform calculations and store data, with the potential to be millions of times more powerful than the most advanced modern computers.
Dzurak’s research partner Andrea Morello said quantum computers, which could run 1 million parallel computations at once compared with a desktop PC’s single-computation capacity, could do things that were currently impossible.
“These include data-intensive problems, such as cracking modern encryption codes, searching databases, and modeling biological molecules and drugs,” he said.
Morello said the study was significant because it was the first time silicon had been used — a well understood and easily accessed material used in countless everyday electronics devices.
Archeologists in Peru on Thursday said they found the 5,000-year-old remains of a noblewoman at the sacred city of Caral, revealing the important role played by women in the oldest center of civilization in the Americas. “What has been discovered corresponds to a woman who apparently had elevated status, an elite woman,” archeologist David Palomino said. The mummy was found in Aspero, a sacred site within the city of Caral that was a garbage dump for more than 30 years until becoming an archeological site in the 1990s. Palomino said the carefully preserved remains, dating to 3,000BC, contained skin, part of the
TRUMP EFFECT: The win capped one of the most dramatic turnarounds in Canadian political history after the Conservatives had led the Liberals by more than 20 points Canadian Prime Minister Mark Carney yesterday pledged to win US President Donald Trump’s trade war after winning Canada’s election and leading his Liberal Party to another term in power. Following a campaign dominated by Trump’s tariffs and annexation threats, Carney promised to chart “a new path forward” in a world “fundamentally changed” by a US that is newly hostile to free trade. “We are over the shock of the American betrayal, but we should never forget the lessons,” said Carney, who led the central banks of Canada and the UK before entering politics earlier this year. “We will win this trade war and
‘BODIES EVERYWHERE’: The incident occurred at a Filipino festival celebrating an anti-colonial leader, with the driver described as a ‘lone suspect’ known to police Canadian police arrested a man on Saturday after a car plowed into a street party in the western Canadian city of Vancouver, killing a number of people. Authorities said the incident happened shortly after 8pm in Vancouver’s Sunset on Fraser neighborhood as members of the Filipino community gathered to celebrate Lapu Lapu Day. The festival, which commemorates a Filipino anti-colonial leader from the 16th century, falls this year on the weekend before Canada’s election. A 30-year-old local man was arrested at the scene, Vancouver police wrote on X. The driver was a “lone suspect” known to police, a police spokesperson told journalists at the
North Korean leader Kim Jong-un has unveiled a new naval destroyer, claiming it as a significant advancement toward his goal of expanding the operational range and preemptive strike capabilities of his nuclear-armed military, state media said yesterday. North Korea’s state-run Korean Central News Agency (KCNA) said Kim attended the launching ceremony for the 5,000-tonne warship on Friday at the western port of Nampo. Kim framed the arms buildup as a response to perceived threats from the US and its allies in Asia, who have been expanding joint military exercises amid rising tensions over the North’s nuclear program. He added that the acquisition
