Microsoft and Quantinuum have demonstrated 12 logical qubits built from 97 physical qubits, running fault-tolerant algorithms ...

Neutral atom quantum computing works by using lasers to corral atoms into a vacuum chamber (not on a chip per se). Different ...

Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only ...

Atom Computing has built a neutral-atom quantum processor containing 1,225 qubits, making it one of the largest qubit arrays ...

In the previous article titled “The Basics: How Quantum Computers Work and Where the Technology is Heading,” we provided an overview of foundational quantum computing concepts, including qubits ...

Quantum computers have the potential to transform science, accelerating breakthroughs in drug development, cosmology, ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

The path to quantum supremacy is made challenging by the issues associated with scaling up the number of qubits. One key problem is the way that qubits are measured. A research group introduces a new ...

Researchers at QuTech in Delft, The Netherlands, have developed a new chip architecture that could make it easier to test and scale up quantum processors based on semiconductor spin qubits Researchers ...

Conventional computers work by performing operations on bits encoded in silicon. But no one is really sure how qubits will be encoded in the quantum computers of the future. Half a dozen or so ...

Quantum computing advances raise concerns over 10,000 qubits breaking P‑256 encryption using Shor’s algorithm, driving ...

An artistic illustration shows how microscopic bolometers (depicted on the right) can be used to sense very weak radiation emitted from qubits (depicted on the left). Chasing ever-higher qubit counts ...
