It's a well-known fact that quantum calculations are difficult, but one would think that quantum computers would facilitate the process. In most cases, this is true.

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers ...

While this may complicate the quest for a clear experimental signature of quantum gravity, it does not render such tests useless. According to the research team, both classical and quantum models of ...

This week, researchers published LIGO findings that hint at the existence of second-generation black holes. Astronomers ...

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

The Nobel Prize in Physics for 2025 honors scaled-up quantum physics—while sidestepping controversies swirling around quantum ...

The 2025 Homi Bhabha lecturer Rupamanjari Ghosh is a leading expert in quantum optics and a transformative figure in higher ...

Ask a bunch of physicists to explain a quantum experiment and you’re unlikely to get the same description twice. Everyone agrees that the mathematical framework of quantum mechanics is peerless at ...

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 ...

Google's Willow quantum chip stuns scientists with 13,000× speed boost over top supercomputers in physics simulation.
