Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow of time and ...

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.

Quantum control is the science and engineering of steering quantum systems into desired states, dynamics, or measurement outcomes using fields, pulses, feedback, and optimized protocols. It is ...

Qubits, the heart of quantum computers, can change performance in fractions of a second — but until now, scientists couldn’t see it happening. Researchers at NBI have built a real-time monitoring ...

In a study published in Nature Communications, a research team demonstrates the all-electrical control of quantum interference in individual atomic spins on a surface. Quantum interference arises when ...

Quantum technologies promise revolutionary advances in computing, sensing and information processing. However, controlling individual quantum bits (qubits) at the atomic scale remains a major ...

Quantum control theory in stochastic systems addresses the challenge of steering quantum dynamics in the presence of environmental noise and measurement back-action. At its core lies the description ...
