The squeezer - an optical parametric oscillator (OPO) that uses a nonlinear crystal inside an optical cavity to manipulate the quantum fluctuations of light. - is responsible for the entanglement.

When sand grains wedge together in a funnel, the whole column locks up. Something strikingly similar can happen to quantum ...

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional ...

Quantum entanglement—once dismissed by Albert Einstein as “spooky action at a distance”—has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum ...

Communication is how we connect, and it’s always changing. Think about how we used to send messages versus now with the ...

Teleportation. Imagine instantly transporting to a remote location like moving from your home to the office with no commute whatsoever. It's technology you always see incorporated in sci-fi media, ...

In optical interferometry, waves of a light signal travel to separate light collectors, and the interference pattern formed by superimposing the waves reveals spatial information about the light ...

Mehdi Namazi wants to sell you quantum entanglement. He and his colleagues at Qunnect have spent nearly a decade building devices that make sharing quantum-entangled particles of light, or photons, ...
