这次的进展大幅超越Google于2019年宣布的成果。当时，其量子处理器Sycamore在三分钟内完成了一项数学计算，而相同任务超级计算机则需10,000年。尽管IBM对此提出质疑，但Google此次的成果无疑更具说服力。量子计算的核心在于量子比特（qubit），这是一种能同时处于0、1和介于两者之间状态的单位。然而，量子比特容易因与外...
The Zuchongzhi-3 chip vastly outperforms Google’s Sycamore chip, according to its creators Mar 14, 2025 18:29 Google must pay South African media over $27mn annually – committee A local investigation has found a “definite” bias in the search engine’s algorithm, which disadvantages the ...
Consider that the Willow chip only has 105 physical qubits. Achieving quantum advantage will require a thousand or more logical qubits, as I pointed out above. You can do the math on a napkin and see how far away we are from that. Plus, other industry players such as Microsoft are explor...
Google engineers have defended their Sycamore chip Google After a month of waiting, Google has finally broken its silence on quantum supremacy. On 23 October, engineers at the firm released a paper claiming that they have built a quantum computer that can solve a problem that cannot realistically...
Staking its claim for “quantum supremacy,” the company pulls back the curtain on its landmark Sycamore chip
Google's Sycamore chip is kept cool inside their quantum cryostat. (Image credit: Eric Lucero/Google, Inc.) Google just took a quantum leap in computer science. Using the company's state-of-the-art quantum computer, called Sycamore, Google has claimed "quantum supremacy" over the most ...
A downsized version of the company’s Sycamore chip performed a record-breaking simulation of a chemical reaction ByNeil Savageedited byLee Billings Getty Images When researchers at Google announced last fall that they had achieved “quantum superiority”—a point at which a quantum computer can per...
Google has announced its latest quantum computing chip, known as Willow, another addition to the Quantum AI lab at Google.
While the effects are negligible for individual qubits, they become significant when scaled to arrays of qubits positioned at varying heights on vertically aligned chips, such as Google’s Sycamore chip. The researchers developed a protocol based on phase estimation to measure these shifts with high...
Google scaled from a 3×3 to a 7×7 physical qubit lattice while reducing the error rate by a factor of 2.14, effectively doubling the lifespan of logical qubits compared to its earlier Sycamore chip. This achievement demonstrates that we can add more physical qubits while exponentially ...
