First Experimental Observations of Knots in Quantum Matter

Knot solitons, or knotted solitary waves, have been successfully created in a quantum-mechanical field that describes a gas of superfluid atoms, known as Bose-Einstein condensate.

New Way to Affect Dynamical Nonlocality in Nanoscale Quantum Circuits

Researchers at the MESA+ research institute at the University of Twente have identified a new fundamental quantum mechanical property of electrical currents in nanoscale quantum circuits.

NIST Develops New Mixed-Atom Gates for Quantum Computing

Physicists at the National Institute of Standards and Technology (NIST) have added to their collection of ingredients for future quantum computers by performing logic operations--basic computing steps--with two atoms of different elements. This hybrid design could be an advantage in large computers and networks based on quantum physics.

New Class of Topological Insulators Shows Promise for Spintronics, Quantum Computing

Topological insulators are materials that let electric current flow across their surface while keeping it from passing it through their bulk. This exotic property makes topological insulators very promising for electricity with less energy loss, spintronics, and perhaps even quantum computing.

MIT Professor Explains Google’s New Quantum-Computing Paper

In 2010, a Canadian company called D-Wave announced that it had begun production of what it called the world’s first commercial quantum computer, which was based on theoretical work done at MIT.

Quantum Computer Could Solve Insoluble Problems Even When Travelling Along 'Open Timelike Curves'

Why send a message back in time, but lock it so that no one can ever read the contents? Because it may be the key to solving currently intractable problems. That's the claim of an international collaboration who have just published a paper in npj Quantum Information.

Peter Zoller Honored with 2016 Herbert Walther Award

The Optical Society (OSA) and the Deutsche Physikalische Gesellschaft (DPG) announced that the 2016 Herbert Walther Award will be presented to Peter Zoller, Institute for Theoretical Physics, Universität Innsbruck, Austria, for his pioneering discoveries and development of new interdisciplinary quantum science that unifies quantum optics, atomic, molecular, optical and condensed matter which have opened new paths toward future applications in quantum technology.

Researchers Look at Localization and Ergodicity-Breaking Behavior of Atoms

Two physical phenomena, localization and ergodicity-breaking, are conjoined in new experimental and theoretical work. Before we consider possible implications for fundamental physics and for prospective quantum computing, let’s first look at these two topics in turn. It will bear providing some specific examples before getting to the quantum details.

Researchers Propose New QKD-Based Quantum Private Query to Reduce Failure Probability

Cryptography is the approach to protect data secrecy in public environment. Certain cryptographic communications require not only the security of the transmitted message against eavesdropping from an outside adversary, but also the communicators' individual privacy against each other. Symmetrically private information retrieval (SPIR), which deals with the problem of private user queries to a database, is an example of such communication protocols.
