To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could just physics smarter and build one on a lab ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Quantum Space is acquiring propulsion technologies and facilities from Phase Four to support development of its Ranger ...

A quantum computer has reached new heights. The first quantum computer in space is now orbiting Earth on a satellite, scientists report. Launched on June 23, the computer had to be designed to fit in ...

When the X-37B launches on its eighth mission no earlier than Aug. 21, it will carry an experimental quantum inertial sensor. This article was originally published at The Conversation. The publication ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

An international team of researchers has developed a photonic quantum computer designed to operate in the harsh environment of space. The computer was integrated into a satellite and launched into ...
