Physicists have achieved a breakthrough by using a 58-qubit quantum computer to create and observe a long-theorized but never ...

Made out of a fluorescent protein, the qubit is just 3 nanometers in diameter, scientists report August 20 in Nature. By hitting the protein with laser light, tweaking it with microwaves and observing ...

D-Wave’s Advantage2 system delivers 4,400+ qubits, 20-way connectivity, a 40% higher energy scale, and double coherence time.

在实验室中对一个n量子比特态进行认证，以证明它与一个给定的目标态足够接近，是量子信息科学中的一项基础任务。然而，目前适用于通用目标态的严格协议，在资源需求上可能令人望而却步，因为它们要么需要深层量子线路，要么需要指数级数量的单量子比特测量。9月8日， ...

PsiQuantum Inc., a well-funded quantum computing startup, said today it has raised $1 billion in late-stage funding to ...

Scientists invent a new device that aims to solve thermal interference from electronic components — one of the biggest ...

In March, D-Wave announced it performed a materials simulation using quantum technology. A few weeks later, Quantinuum published a paper in Nature detailing how it used the company’s six-qubit ...

PsiQuantum today announced it has raised $1 billion in funding for its Series E round to build the world’s first commercially ...

IBM is racing Google, Amazon, Microsoft and a handful of startups to build the world’s first viable quantum computer.

眼前是一道公认的世界级难题：若交给当今最快的超级经典计算机，需要百万亿年才能算出答案。然而，就在一眨眼间，一台全新机器给出了精确结果——这并非科幻，而是刚刚发生的现实。它就是由中国科学技术大学潘建伟、朱晓波、彭承志等团队联合攻关研制出的超导量子计算原 ...

Noise is annoying, whether you're trying to sleep or exploit the laws of quantum physics. Although noise from environmental ...
