New spin-squeezing techniques let atoms work together for better quantum measurements
Higher accuracy atomic clocks, such as the “tweezer clock” depicted here, could result from linking or “entangling” atoms in a new way through a method known as “spin squeezing,” in…
What is quantum squeezing?

In search of the theory of gravity
As new and powerful telescopes gather new data about the universe, they reveal the limits of older theories. Credit: Shutterstock Einstein’s theory of gravity—general relativity—has been very successful for more…
Can cloud-based quantum computing really offer a quantum advantage?
The input to the service is a user-designed quantum circuit. The service begins with qubit allocation, which relates physical qubits to a designed circuit. An implementation of the circuit is…
How Radio Astronomy Sees Magnetic Fields
Newswise — Many objects in the Universe have magnetic fields. Planets such as Earth and Jupiter, the Sun and other stars, even galaxies billions of light years away. But these…
