A growing body of theoretical and experimental work in physics is converging on a striking possibility: time, the dimension humans experience as a constant forward flow, may not be a fundamental ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

Experts are calling for the cryptographic systems on which the entire network depends to be made ready now for the imminent ...

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...

Quantum computers use qubits, which are based on quantum physics, allowing them to solve complex problems far faster than ...
