Quantum computing in 2026 still isn't a faster laptop. It doesn't make email snappier, and it won't speed up spreadsheets.

In a paper published on Wednesday, Google researchers claimed its quantum computer can, for the first time, perform a task "beyond the reach of the fastest classical supercomputers." Google said it ...

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

New research published in Nature shows evidence of quantum utility Backed by this evidence, IBM to upgrade its full fleet of IBM Quantum systems to large-scale quantum processors over 100+ qubits Top ...

What is quantum computing, really? We explain qubits, superposition, and the quantum threat to encryption — in plain English, with no PhD required.

A new study published in Science confirms quantum computing “supremacy” over classical computing, says the CEO of Vancouver quantum computer company D-Wave Quantum Inc. (NYSE:QBTS). “We have shown ...

The University of Waterloo last month announced the creation of a minuscule device – so tiny it can fit more than a million times over on a grain of sugar – that twisted and expanded neutron beams ...

A new ultra-fast monitoring system reveals that quantum computer qubits can change from stable to unstable in mere milliseconds.
