On his blog Bruce Schneier writes "I'm always in favor of security research, and I have enjoyed following the developments in quantum cryptography. But as a product, it has no future. It's not that quantum cryptography might be insecure; it's that cryptography is already sufficiently secure."

Atoms have been combined for the first time into tightly bound molecules in large numbers at temperatures close to absolute zero.
This is good news for scientists who hope to have greater control over basic chemical reactions and for those who want to build a new
kind of computer, one based on mysterious quantum behavior.

How heavy or how big can an object be before losing its quantum properties and obeying to the laws of classical physics? This question drives many research groups all around the globe. Answers still remain to be given as currently there are no systems which allow observing the expected tiny signatures of quantum effects in macroscopic objects. The novel system developed in the MPG Junior Research Group “Laboratory of Photonics” led by Dr. Tobias Kippenberg could resolve this problem.

For years, physicists have been heralding the revolutionary potential of using quantum mechanics to build a new generation of supercomputers, unbreakable codes, and ultra-fast and secure communication networks. The brave new world of quantum technology may be a big step closer to reality thanks to a team of University of Calgary researchers that has come up with a unique new way of testing quantum devices to determine their function and accuracy.

Researchers at the US National Institute of Standards and Technology (NIST) have demonstrated a technique that could make quantum cryptography significantly cheaper to implement, moving it nearer to possible commercial acceptance.

Researchers in the UK have taken a small but important step towards the creation of practical quantum computers by creating the first logic gates on a silicon chip that can process individual photons. The chip, which measures several millimetres across, reproduces an earlier version of the gate that occupied several square metres of space on an optical bench.
