Xanadu Quantum Technologies Inc., which aims to commercialize quantum computing using particles of light, has raised $100 million in new funding as investor interest in the industry heats up.On Tuesday, Xanadu announced a Series B funding led by Bessemer Venture Partners, one of Silicon Valley’s oldest such firms. Funding to date for the five-year-old company now totals $145 million, said Christian Weedbrook, founder and chief executive of Xanadu. Quantum computing has the potential to solve some problems many millions of times faster than a conventional computer, which is why major technology companies and startups are working to commercialize it using various approaches. Traditional computers store information as either zeros or ones. Quantum computers use quantum bits, or qubits, which represent and...

Google Aims for Commercial-Grade Quantum Computer by 2029

Alphabet Inc.’s Google plans to spend several billion dollars to build a quantum computer by 2029 that can perform large-scale business and scientific calculations without errors, said Hartmut Neven, a distinguished scientist at Google who oversees the company’s Quantum AI program. The company recently opened an expanded California-based campus focused on the effort, he said.“We are at this inflection point,” said Dr. Neven, who has been researching quantum computing at Google since 2006. “We now have the important components in hand that make us confident. We know how to execute the road map.” Chief Executive Sundar Pichai announced the timeline and introduced the new Google Quantum AI campus in Santa Barbara County on Tuesday at Google’s annual developer...

Precision Is Nature’s Gift to Technology

Nobel Prize-winning physicist Frank Wilczek explores the secrets of the cosmos. Read previous columns here. Precision is a powerful tool, but it can be hard to come by. That theme, with variations, is a leitmotif of science, organic life and modern technology. It is sounding again today, at the frontier of quantum computing. Consider biology. Complex organisms store their essential operating systems—instructions for how to build cells and keep them going—within long DNA molecules. Those basic programs must be read out and translated into chemical events. Errors in translation can be catastrophic, resulting in defective, dysfunctional proteins or even in cancers. So biology has evolved an elaborate machinery of repair and proofreading to keep error rates low—around one per billion operations. A series of complicated...

Amazon’s Bid to Recover JEDI Cloud Computing Contract Stays Alive

social
WASHINGTON— Amazon. com Inc.’s bid to win back the Pentagon’s JEDI cloud computing contract stayed alive Wednesday as a federal judge rejected motions by the Defense Department and Microsoft Corp. to dismiss much of Amazon’s challenge of the contract award. Judge Patricia Campbell-Smith of the U.S. Court of Federal Claims rejected the motions, according to a court docket entry. Her opinion and order in the case weren’t made public immediately, making the extent of the government’s legal defeat unclear. The move is significant nonetheless because it opens the door to continued protracted court battles over the Joint Enterprise Defense Infrastructure, or JEDI, contract. ...

Quantum Computing Scientists Call for Ethical Guidelines

A group of quantum computing experts, including scientists and company executives, want to raise ethical concerns about the technology’s potential to create new materials for war and accelerate human DNA manipulation.Six experts are featured in a 13-minute video titled “Quantum Ethics: A Call to Action,” which goes live Monday on YouTube and the Quantum Daily, a free online source for quantum computing news. The goal of the video, which features a former quantum chief at Alphabet Inc.’s Google, is to kick off conversations with other quantum computing industry leaders about the ethical implications of the technology. “Whenever we have a new computing power, there is potential for benefit of humanity, [but] you can imagine ways that it would also hurt people,” said John Martinis, professor of...
