First noiseless single photon amplifier

Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise.

'Quantum magic' without any 'spooky action at a distance'

The quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as "spooky action at a distance". A team of researchers led by Anton Zeilinger at the ...

Straightening messy correlations with a quantum comb

Quantum computing promises ultra-fast communication, computation and more powerful ways to encrypt sensitive information. But trying to use quantum states as carriers of information is an extremely delicate business. Now ...
