Physicists have designed a set of quantum control protocols that can make a monitored quantum process look as though time is flowing backward, forward at a different speed, or in no clear direction at ...

Researchers from the Austrian Academy of Sciences and the University of Vienna have demonstrated a precise method for reversing time in a quantum system, achieving an average fidelity of more than 95% ...

A method that can reverse the flow of time in quantum systems could one day be used to help charge quantum batteries. For every process we observe in the universe, events appear to happen in only one ...

Irvine, Calif., April 13, 2026 — Quantum computers stand to revolutionize research by helping investigators solve certain problems exponentially faster than with conventional computers. Current ...

Digital secrets are protected by encryption, which converts meaningful data into an unintelligible form. If quantum computers ...

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 ...

A time crystal more complex than any made before has been created in a quantum computer. Exploring the properties of this unusual quantum setup strengthens the case for quantum computers as machines ...

The Nvidia logo outside the company's offices in Shanghai, China, on Monday, Sept. 22, 2025. In the last two weeks, NVIDIA, the enabler and chief beneficiary of the AI craze, has bought into quantum ...

In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The ...
