The trick to creating a better quantum sensor? Just give it a little squeeze. For the first time ever, scientists have used a technique called “quantum squeezing” to improve the gas sensing ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

Researchers have created a new ultra-broadband electro-optic comb that packs 450 nm of light precision into a chip smaller than a coin, paving the way for smarter, more efficient photonic devices. In ...
