Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small ...

Australia's Q-Control just proved a ship can navigate for six days with zero GPS using quantum gravimeters that read Earth's gravitational fingerprint. Here's why this changes precision warfare ...

Modern cosmology assumes dark matter exists. But what makes us so certain that dark matter is the answer—and what if we're wrong?

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where a particle does not have a single definite value of position or momentum ...

Laser light is injected into an optical cavity to continuously measure the position of a movable mirror. The output light is read out by homodyne detection, and the measurement data are analyzed using ...

For the first time, scientists have observed quantum entanglement in the way atoms physically move — bringing a phenomenon once described by Albert Einstein as "spooky action at a distance" into even ...

The Big Bang is often described as the moment everything began — a point of infinite density where the laws of physics broke down. But what if that picture is incomplete? A new study proposes a ...

Quantum computing, once hailed as a new advancement, has encountered significant challenges that have tempered early optimism. Sabine Hossenfelder explores the technical and practical obstacles that ...

With $20 M funding so far, Quantum Gravity Gradiometer Pathfinder Mission is intended to “advance U.S. space sensing”. 16 February 2026 Red indicates areas of the world that exert greater ...

Infleqtion, which designs and builds quantum computers, precision sensors, and quantum software, is collaborating with NASA to launch the world's first quantum gravity sensor into low Earth orbit.

With more than $20 million in contracted mission funding to date, the Quantum Gravity Gradiometer Pathfinder Mission, Led by NASA’s Jet Propulsion Laboratory in Southern California, Advances U.S.
