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 ...

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 ...

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 ...

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 ...

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 ...

Quantum computing has imprinted itself on our society as a weird, wacky way of computing that most of us can’t comprehend.

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 ...

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 ...

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 ...

Among the troublesome hurdles of this scaling-up race is refining how qubits are measured. Devices called parametric amplifiers are traditionally used to do these measurements. But as the name ...
