A Bose-Einstein condensate emmits quantum mechanically correlated atoms in an atom-chip
Objects that are well separated in space but still cannot be understood separately belong to the profoundest mysteries of quantum physics. Pairs of photons are prominent examples of such systems. They allow the teleportation of…

14 quantum bits calculation record
Quantum physicists from the University of Innsbruck have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. With…

Atomic Antennas Transmit Quantum Information Across a Microchip
The Austrian research group led by physicist Rainer Blatt suggests a fundamentally novel architecture for quantum computation. They have experimentally demonstrated quantum antennas, which enable the exchange of quantum information between two separate memory cells…

New Tool for Managing Ultracold Gases: Electric Fields
Physicists at JILA have demonstrated a new tool with regard to controlling ultracold gas as well as ultracold chemistry: electric fields. As described in the April 29 issue of Nature,* JILA scientists discovered that applying…

Quantum Information: Disentangling a Billion-Dollar Opportunity
The field of quantum information processing has come a long way in the past five years, partly thanks to a £10 million grant from the Engineering and Physical Sciences Research Council (EPSRC) which has helped…

Cooler, Faster Computing with light within photonic crystals
University of Toronto quantum optics researchers Sajeev John and Xun Ma have discovered new behaviours of light within photonic crystals that could lead to faster optical information processing and compact computers that don’t overheat. “We…

Quantum Device Traps, Detects And Manipulates The Spin Of Single Electrons
A novel device, developed by a team led by University at Buffalo engineers, simply and conveniently traps, detects and manipulates the single spin of an electron, overcoming some major obstacles that have prevented progress toward…
