Lasers are often used to look at objects in microscopes. But even the best laser has “quantum noise” that makes a picture blurry and hides the details. This in turn results in measurements that are ...

“Squeezing” noise over a broad frequency bandwidth in a quantum system could lead to faster and more accurate quantum measurements. A certain amount of noise is inherent in any quantum system. For ...

Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum ...

This superconducting parametric amplifier can achieve quantum squeezing over much broader bandwidths than other designs, which could lead to faster and more accurate quantum measurements. Credit: Jack ...
