Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

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

Researchers developed compilation-based quantum process tomography, a framework that reconstructs quantum operations using fewer measurements than conventional methods.

The Kirq test bed in Quebec City, Canada is the nation’s only measurement facility capable of testing communications networks for security against cyberattacks from quantum ...

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

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...

Devices that can confine individual electrons are potential building blocks for quantum information systems. But the electrons must be protected from external disturbances. RIKEN researchers have now ...

By uncovering previously hidden dynamics, the findings reshape how scientists think about testing and calibrating superconducting quantum processors.

A wafer-thin layer of rust, formed naturally in air, helped researchers spot a behavior many physicists have chased for decades. That oxide, hematite (α-Fe2O3), appeared on the top layer of a stacked ...

Connecticut has become a budding center of quantum technology, according to Michelle Parlos, an economist in Scanlon’s office ...

China's confidence to open up its quantum computing service to the world and to export components of quantum computers to ...
