'Swing-Dancing' Pairs of Electrons Discovered

May 13, 2015 — Scientists have discovered electrons that can 'swing dance.' This unique electronic behavior can potentially lead to new families of quantum ... read more

Quantum Computers: Blind Signatures Using Offline Repositories for a New Level of Security

May 13, 2015 — In the new era of quantum computers, many daily life applications, such as home banking, are doomed to failure, researchers say, adding that new forms of ensuring the confidentiality of our data are ... read more

May 12, 2015 — Topological insulators are "strange" materials, insulators on the inside and conductors on the surface. They also have properties that make them excellent candidates for the development of ... read more

May 11, 2015 — Rydberg atoms, atoms whose outermost electrons are highly excited but not ionized, might be just the thing for processing quantum information. These outsized atoms can be sustained for a long time in ... read more

May 6, 2015 — Scientists have discovered topologically protected 1-D electron conducting channels at the domain walls of bilayer graphene that should prove useful for ... read more

May 5, 2015 — Quantum computers are in theory capable of simulating the interactions of molecules at a level of detail far beyond the capabilities of even the largest supercomputers today. Such simulations could ... read more

Defects in Atomically Thin Semiconductor Emit Single Photons

May 4, 2015 — Researchers have shown that defects on an atomically thin semiconductor can produce light-emitting quantum dots. The quantum dots serve as a source of single photons and could be useful for the ... read more

Quantum Particles at Play: Game Theory Elucidates the Collective Behavior of Bosons

Apr. 28, 2015 — Quantum particles behave in strange ways and are often difficult to study experimentally. Using mathematical methods drawn from game theory, physicists have shown how bosons, which like to enter the ... read more

Apr. 27, 2015 — The 'holographic principle,' the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange ... read more

Apr. 23, 2015 — Thermal imaging, microscopy and ultra-trace sensing could take a quantum leap with a new technique. Scientists used quantum correlated beams of light to overcome the fundamental detection limit of ... read more

Apr. 23, 2015 — Scientists have created an electronic device so accurate that it can detect the charge of a single electron in less than one microsecond. It has been dubbed the 'gate sensor' and could be ... read more

Reducing Big Data Using Ideas from Quantum Theory Makes It Easier to Interpret

Apr. 23, 2015 — Analysing the large volumes of data gathered by modern businesses and public services is problematic. Traditionally, relationships between the different parts of a network have been  represented  ... read more

Quantum Cryptography at the Speed of Light: Researchers Design First All-Photonic Repeaters

Apr. 15, 2015 — Engineers bring perfectly secure information exchanges one step to reality. They have now designed the first all-photonic quantum repeaters -- protocols that ensure data can be carried reliably and ... read more

Quantum Hall Effect: Quantization of 'Surface Dirac States' Could Lead to Exotic Applications

Apr. 14, 2015 — Researchers have uncovered the first evidence of an unusual quantum phenomenon -- the integer quantum Hall effect -- in a new type of film, called a 3-D topological insulator. This discovery could ... read more

Apr. 13, 2015 — Physicists have narrowed the theoretical limits for where the 'speed limit' lies for quantum computers. The findings, which offer a better description of how quickly information can travel ... read more

Apr. 10, 2015 — Scientists have encoded quantum information in silicon using simple electrical pulses for the first time, bringing the construction of affordable large-scale quantum computers one step closer to ... read more

Apr. 9, 2015 — Temperature is a statistical concept. Very small systems, consisting of a small number of particles, are not usually described statistically. Scientists have now measured how quantum systems reach a ... read more

Apr. 9, 2015 — For the first time, physicists have achieved interference between two separate atoms: when sent towards the opposite sides of a semi-transparent mirror, the two atoms always emerge together. This ... read more

Apr. 8, 2015 — Light has been slowed down by coupling atoms to glass fibers. This technology is an important prerequisite for a future worldwide quantum ... read more

Physicists Create New Molecule With Record-Setting Dipole Moment

Apr. 3, 2015 — A proposed pathway to construct quantum computers may be the outcome of research by a physics team that has created a new molecule based on the interaction between a highly-excited type of atom known ... read more
