The changes are coming on two fronts. On one, tech giants such as IBM and Google are racing to build ever-larger quantum computers: IBM hopes to achieve a genuine advantage over classical computers in ...

Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some advanced tasks. These systems rely on qubits, the fundamental ...

“In quantum computers, information is transmitted and stored using so-called qubits (quantum bits). But quantum information ...

With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to ...

New research suggests that a quantum computer could crack a crucial cryptography method with just 10,000 qubits.

The system is currently performing at a 99.1% median two-qubit gate fidelity with a gate speed of ~60 ns and a 99.9% median single-gate fidelity. Rigetti is releasing Cepheus-1-108Q now in response to ...

A method reduces the number of qubits needed for quantum computers, making practical machines possible sooner and affecting ...

Researchers at ETH Zurich have realized particularly stable quantum logical operations with qubits made of neutral atoms.

Infrastructure, not qubits, is emerging as the main constraint on quantum computing’s path to real-world use. The view came ...

Future quantum computers will need to be less powerful than we thought to threaten the security of encrypted messages.

Two companies that are racing to develop a photonic quantum computer using photonic qubits are PsiQuantum, based in Palo Alto ...
