The quantum computer used in the team's experiment relied on a bespoke platform that eschews the more common architecture that uses photons as qubits — the quantum equivalent of computer bits ...

But as quantum processing units (QPUs) become smaller, more power-efficient, and better at detecting errors, quantum computing systems will likely become more practical for handling mainstream ...

Quantum computing has captured imaginations for almost 50 years. The reason is simple: it offers a path to solving problems that could never be answered with classical machines.

Quantum computer makers track that with a measurement called gate fidelity. Rigetti is at 95% to 97% fidelity today, but prototypes for its fourth-generation Ankaa-based systems have shown 99% ...

Qubits are the basic units of information in quantum computing, akin to a bit on a classical computer. While bits represent either 0 or 1, qubits can be both at the same time.

The quantum computer, however, is an entirely difference concept – the reason it’s quantum is that it doesn’t use binary logic. By its nature a quantum computer is a yes/no/both device.

"Quantum computing has been around since the 1980s, but over the past few years, we've come closer to both scaling the technology to a point where it can be used in real life as well as ...

Quantum computing progress can be assessed by the number of qubits (basic units of information) in one processor. Today, the most powerful quantum computers process between 100 and 1,000 qubits.

A quantum computer, on the other hand, might do the same work in just minutes, rendering modern cryptography obsolete. When cryptography collapses so, too, does network security.

Quantum computing is just in its infancy. Companies are racing to build their best platform, which is no small task, considering how difficult quantum computing is to do well.

Quantum computing’s value to our physical infrastructure may not be obvious, but it's critical that infrastructure leaders start taking an interest in quantum computing and its ability to ...

According to data from The Quantum Insider, quantum vendors sold $854 million worth of computer systems in 2024, compared with $494 million in 2023. The industry doubled its sales of full-stack ...
