Quantum systems tend to become less “quantum-y” as they interact with their environment. So when developing a mathematical description, it’s usually simpler just to view them as being closed off from ...

An experiment with ultracold atoms reveals that a strongly driven quantum system doesn’t always heat up as expected. In daily life, doing work on something over and over usually makes it warmer. You ...

Quantum computing promises extraordinary power, but that same power may expose new security weaknesses. Quantum computers are expected to deliver dramatic gains in processing speed and capability, ...

Physicists have identified a new superfluid phase in a class of quantum systems that, until recently, looked too unstable and ...

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical ...

Scientists at the Institute for Photonic Quantum Systems (PhoQS) and the Paderborn Center for Parallel Computing (PC2) at Paderborn University have developed a powerful open-source software tool that ...

A new chip-based quantum memory uses nanoprinted “light cages” to trap light inside atomic vapor, enabling fast, reliable ...
