Quantum repeaters use defects in diamond to interconnect quantum systems
A packaged prototype quantum repeater module (center), mounted on a gold-plated copper assembly and connected to printed circuit boards (green), features eight optical memories that store qubits in a silicon…
Antimatter falls down, physicists confirm
Newswise — Calgary, AB – The physics behind antimatter is one of the world’s greatest mysteries. Looking as far back as The Big Bang, physics has predicted that when we…
A new kind of chip for quantum technology
An optical image of the electrically controlled coupled cavity array in the team’s silicon photonic chip. The image depicts the wiring structure and optical micrograph of the coupled cavity array.…
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…
