In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today's best versions. "The real challenge, the thing that ...

A cryostat from a quantum computer stands during a press tour of the Leibniz Computing Center in 2022. Qubit is a key term in one of the most buzzy areas of technology: quantum computing. Qubits are ...

Researchers have developed a novel superconducting qubit architecture that can perform operations between qubits with much higher accuracy than scientists have yet been able to achieve. This ...

In the world of quantum computing, diamonds might be an engineer’s best friend. That’s because a fabled, super-pure type of gem mined from the Ural Mountains has quantum properties that could provide ...

We’re nearing the end of the year, and there are typically a flood of announcements regarding quantum computers around now, in part because some companies want to live up to promised schedules. Most ...

Qubits, the heart of quantum computers, can change performance in fractions of a second — but until now, scientists couldn’t see it happening. Researchers at NBI have built a real-time monitoring ...

Spanning a range of hardware platforms, the building-blocks of quantum processors are today sufficiently advanced to begin work on scaling-up these systems into complex quantum machines. A key ...

A new toolbox for sophisticated quantum simulators, in which qubits can directly communicate through so-called “topological radio channels”, has been proposed by physicists in Germany and Spain.

A new study from Caltech and startup Oratomic suggests that quantum computers could break widely used encryption with just 10,000 neutral-atom qubits, far fewer than previous estimates in the millions ...
