D-Wave Systems has carried out a calculation involving 84 qubits on its D-Wave One quantum computing system, Technology Review Physics arXiv blog
Quantum theory is known for its peculiar concepts that appear to contradict the fundamental principles of traditional physics. Researchers have now succeeded in creating a special quantum state between two mesoscopic gases with approximately 500 atoms. The state is known as a “squeezed“ vacuum, in which measuring one gas affects the results of the measurement on the other. To produce these results the team had to develop a novel detection technique to measure values in atomic gases that were previously unobtainable.
Researchers working at the Clarendon Laboratory at the University of Oxford in England have managed to get one small diamond to communicate with another small diamond utilizing "quantum entanglement," one of the more mind-blowing features of quantum physics.
Researchers at the University of Pittsburgh have made advances in better understanding correlated quantum matter that could change technology as we know it, according to a study published in the Nov. 20 edition of <em>Nature</em>.
(PhysOrg.com) -- Research by Los Alamos scientists published today in the journal Nature documents significant progress in understanding the phenomenon of quantum-dot blinking. Their findings should enhance the ability of biologists to track single particles, enable technologists to create novel light-emitting diodes and single-photon sources, and boost efforts of energy researchers to develop new types of highly efficient solar cells.
(PhysOrg.com) -- Engineers and physicists at Harvard have managed to capture light in tiny diamond pillars embedded in silver, releasing a stream of single photons at a controllable rate.
Researchers at the Kavli Institute of Nanoscience at TU Delft in the Netherlands have demonstrated that electrons can move freely in layers of linked
Just because consciousness is a mystery and quantum theory is mysterious, it doesn't mean they're connected.
École Polytechnique Fédérale de Lausanne (EPFL) physicists have developed a new theory that shows that dot symmetry in quantum dots (semiconductors that
Physicists in Austria have come considerably closer to their goal to investigate complex phenomena in a model system: They have developed a digital, and therefore, universal quantum simulator in their laboratory, which can, in principle, simulate any physical system efficiently.
Two completely different quantum systems have been successfully joined. This should pave the way to feasible quantum-computer microchips.
Scientists have demonstrated a new technique that dramatically simplifies quantum circuits, bringing quantum computers closer to reality.
Researchers at the University of British Columbia (UCB) and the University of California Santa Barbara (UCSB) have made a major advance in predicting and
