This abstract illustration shows four particles of light can be produced and manipulated in such a way that one can later decide in which quantum state two of the particles... Physicists of the group of Prof.

As numerous companies continue their push to get us to entrust our data to the cloud, there are many still justifiably concerned about the security of cloud computing-based services.

Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics.

A highly sensitive method that requires specially prepared light waves coupled to ultrathin glass fibers can be used to count and interact with a very small number of atoms - making it possible to build extremely sensitive detectors.

Glass fiber cables are indispensable for the internet - now they can also be used as a quantum physics lab.
