One intriguing method that could be used to form the qubits needed for quantum computers involves electrons hovering above liquid helium. But it wasn't clear how data in this form could be read easily ...

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 ...

Using commercially available technology and innovative methods, researchers at NBI have pushed the limits of how fast you can detect changes in the sensitive quantum states in the qubit. Their work ...

Superconducting qubit design takes center stage at the 2026 Quantum Device Design Workshop, which opened Monday at UCLA.

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 ...

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 ...

Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of ...

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 if scientists can build and scale the hardware needed to run the machines.

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 ...

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 ...
