Austrian physicist Erwin Schrödinger developed quantum theory’s wave equation, which describes quantum systems as waves that ...

Quantum entanglement can link two objects even when they are separated by extremely large distances. But a new study has found a limit at which such quantum correlations stop – and surprisingly, ...

Scientists have achieved a historic first using lasers to study electron behaviour, revealing new insights into how light ...

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 ...

Physicists at the University of the Witwatersrand in Johannesburg have identified a hidden geometric structure reaching 48 ...

Researchers have succeeded in measuring how energy dissipates in quantum dots by quantifying the entropy they produce. The ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

A new quantum communication method uses the temporal Talbot effect to simplify high-dimensional quantum key distribution.

The original version of this story appeared in Quanta Magazine. In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She ...

Spintronics—a technology that harnesses the electron's magnetic quantum states to carry information—could pave the way for a new generation of ultra-energy-efficient electronics. Yet a major challenge ...
