Kate McAlpine at PhysicsWorld writes: ''Since quantum mechanics was first formulated, a string of physicists including Albert Einstein have been uncomfortable with the idea of entanglement – whereby a group of quantum particles have a closer relationship than allowed by classical physics. As a result, some physicists have proposed alternative theories that allow such close relationships without the need for quantum mechanics.

Chris Lee at ArsTechnics writes: ''Not so long ago, we reported on a paper that purported to blow a hole in quantum key distribution (QKD) systems. Now, researchers at Toshiba have struck back with findings that show that the attack doesn't really work. To which the original authors have replied, "Well, it depends." ''

QCRYPT initiates a new conference series on Quantum Cryptography. The first conference in this series will be held at ETH Zurich and the second at CQT in Singapore. The aim of this series is to bring together researchers working on all aspects of the subject (both on the theoretical and experimental sides) and to support the building of a research community in Quantum Cryptography.

Taking a step toward the realization of futuristic quantum technologies, a team of physicists from China and Germany has demonstrated a key element – an entangling gate – of a quantum teleportation scheme proposed more than 10 years ago. The entangling gate serves as a fundamental building block for applications such as long-distance quantum communication and practical quantum computers.
