Control of Twisted Light at Photon Level Holds Potential for Quantum Computation Applications

An international research group led by scientists from the University of Bristol and the Universities of Glasgow (UK) and Sun Yat-sen and Fudan in China, have demonstrated integrated arrays of emitters of so call 'optical vortex beams' onto a silicon chip. The work is featured on the cover of the latest issue of Science magazine, published tomorrow [19 October 2012].

Princeton-Joint Quantum Institute Collaboration Successfully Excites Spin Qubit Using Resonant Cavity

Qubit-based computing exploiting spooky quantum effects like entanglement and superposition will speed up factoring and searching calculations far above what can be done with mere zero-or-one bits. To domesticate quantum weirdness, however, to make it a fit companion for mass-market electronic technology, many tricky bi-lateral and multi-lateral arrangements---among photons, electrons, circuits, cavities, etc.---need to be negotiated.

Qubits Can Successfully Exist in Topological Superconductor Materials

If quantum computers are ever going to perform all those expected feats of code-breaking and number crunching, then their component qubits---tiny ephemeral quantum cells held in a superposition of internal states---will have to be protected from intervention by the outside world. In other words, decoherence, the loss of the qubits' quantum integrity, has to be postponed.

Researchers at Centre for Quantum Technologies Create and Probe Single Barium Ions

All the apparatus that fills the laboratory of the Microtraps group at the Centre for Quantum Technologies — three heavy metal optical benches densely packed with lasers, lenses, mirrors and above them shelves full of electronics — has been put into service to produce and probe single ions of Barium.
