As the global quantum computing sector shifts from laboratory experimentation to commercial deployment, evaluating hardware vendors requires a holistic framework beyond hardware benchmarking. This ...

Using light to process quantum information is one of the most promising approaches to building future quantum computers.

IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but proving quantum advantage in an absolute sense is difficult. All three ...

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a useful quantum machine. It aims to be the first.

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would ...

Larry Ellison’s company Oracle (NYSE: ORCL) announced on Wednesday that it is bringing Quantinuum’s Helios quantum computer ...

A German startup sells a quantum computer that runs at room temperature in an ordinary server rack, but the qubit count ...

Netherlands-based QuiX Quantum has delivered Carina, the world's first universal photonic quantum computer designed for customer deployment. Unlike most quantum machines, Carina operates at room ...

The world's first portable, room-temperature quantum computer with more than 10 qubits utilizes flawed lab-made diamonds. The ...

Quantinuum’s partnership with Quanta Computer could help the quantum computing company tackle the manufacturing and scalability challenges standing between advanced prototypes and commercial systems.

The only snag was that “Shor’s algorithm”, as it is now known, required something that at the time only existed on university blackboards: a quantum computer. These days, quantum computers—which ...

Another major quantum computing record has been broken, and by a considerable margin: physicists have now built an array containing 6,100 qubits, the largest of its type and way above the thousand or ...
