A Purdue University physicist has observed evidence of long-sought Majorana fermions, special particles that could unleash the potential of fault-tolerant quantum computing. Leonid Rokhinson, an associate professor of physics, led a team that is the first to successfully demonstrate the fractional a.c. Josephson effect, which is a signature of the particles.

The promise of ultrafast quantum computing has moved a step closer to reality with a technique to create rewritable computer chips using a beam of light. Researchers from The City College of New York (CCNY) and the University of California Berkeley (UCB) used light to control the spin of an atom’s nucleus in order to encode information.

Researchers are edging toward the creation of new optical technologies using "nanostructured metamaterials" capable of ultra-efficient transmission of light, with potential applications including advanced solar cells and quantum computing.

The Garching-based physicists are now the first to transmit quantum bits in the form of individual photons from one atom to the other via a 60-metre fibre-optic cable and to reliably store them in the receiver atom. This arrangement is not only suitable for exchanging data between computers, should they, in years to come, compute in quantum bits. It also enables fundamental insight into how quantum communication works, and it could, in future, allow physicists to investigate quantum systems that are not yet understood.

Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. Their paper is about to be published in EPJ B. This study, led by scientists from Zhejiang University, Hangzhou, China, and the Centre for Computational Science and Engineering at the National University of Singapore, could have implications for quantum computers due to improvements in the transport of discrete amounts of information, known as qubits, that are encoded in electrons.

Quantum computing—considered the powerhouse of computational tasks—may have applications in areas outside of pure electronics, according to a University of Pittsburgh researcher and his collaborators.
