CMOS-built optical phase modulators shrink laser control hardware and power use for trapped atom quantum computers, enabling larger stable qubit arrays at work. (Nanowerk News) Researchers have made a ...

It's a well-known fact that quantum calculations are difficult, but one would think that quantum computers would facilitate the process. In most cases, this is true. Quantum bits, or qubits, use ...

Richard Feynman, the iconic physicist and one of the progenitors of quantum computing, famously said in 1981: “Nature isn’t classical, dammit, and if you want to make a simulation of nature, you’d ...

Researchers have created a new type of "quantum operation" that is dramatically more stable than previous methods. The achievement brings one hardware design, in particular — neutral‑atom qubits — a ...

Physicists have achieved a breakthrough by using a 58-qubit quantum computer to create and observe a long-theorized but never-before-seen quantum phase of matter: a Floquet topologically ordered state ...

Quantum computing has long lived in the realm of lab demos and bold PowerPoint slides, but two of the industry’s biggest players now say the first truly useful machines are less than five years away.

Quantinuum has unveiled a third-generation quantum computer that could be easier to scale up than rival approaches. The US- and UK-based company Quantinuum today unveiled Helios, its third-generation ...

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

A time crystal more complex than any made before has been created in a quantum computer. Exploring the properties of this unusual quantum setup strengthens the case for quantum computers as machines ...
