Navigating when GPS goes dark

Words like "tough" or "rugged" are rarely associated with a quantum inertial sensor. The remarkable scientific instrument can measure motion a thousand times more accurately than the devices that help navigate today's missiles, ...

Physicists entangle more than a dozen photons efficiently

Physicists at the Max Planck Institute of Quantum Optics have managed to entangle more than a dozen photons efficiently and in a defined way. They are thus creating a basis for a new type of quantum computer. Their study ...

The photon ring: A black hole ready for its close-up

When scientists unveiled humanity's historic first image of a black hole in 2019—depicting a dark core encircled by a fiery aura of material falling toward it—they believed even richer imagery and insights were waiting ...

Researchers achieve record entanglement of quantum memories

A network in which data transmission is perfectly secure against hacking? If physicists have their way, this will become reality one day with the help of the quantum mechanical phenomenon known as entanglement. For entangled ...

Physicists make leaps in reading out qubits with laser light

Qubits are a basic building block for quantum computers, but they're also notoriously fragile—tricky to observe without erasing their information in the process. Now, new research from the University of Colorado Boulder ...
