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

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

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

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 ...

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

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 ...
