BURNABY, British Columbia and PALO ALTO, Calif., May 22, 2013 /PRNewswire/ -- D-Wave Systems Inc., the world's first commercial quantum computing company, today announced the publication of a peer-reviewed paper entitled "Thermally assisted quantum annealing of a 16-qubit problem" in the journal Nature Communications. The paper presents the results of the first experimental exploration of the effect of thermal noise on quantum annealing. Quantum annealing is the process by which...

JQI lab sets a new record for creating heralded photons HERALDING Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable quantum thing. An important consequence of this inherent kinship is that measuring a property of A (say, the particle's polarization) is necessarily to know the corresponding property of B, even if you're not there with a...

System to be Installed at NASA's Ames Research Center, and Operational in Q3 BURNABY, British Columbia and PALO ALTO, Calif., May 16, 2013 /PRNewswire/ -- D-Wave Systems Inc., the world's first commercial quantum computing company, today announced that its new 512-qubit quantum computer, the D-Wave Two, will be installed at the new Quantum Artificial Intelligence Lab, a collaboration among NASA, Google and the Universities Space Research Association (USRA). The purpose...

University of Vienna Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the Faculty of Physics, University of Vienna succeeded in prototyping a new and highly resource efficient model of a quantum computer – the boson sampling computer. The results will be published in the upcoming issue of the renowned scientific journal "Nature...

Lawrence Berkeley National Laboratory From brain to heart to stomach, the bodies of humans and animals generate weak magnetic fields that a supersensitive detector could use to pinpoint illnesses, trace drugs – and maybe even read minds. Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes. Now scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and...

Enid Burns for redOrbit.com – Your Universe Online Quantum computing just took a step from theory to practice with a test that took place at Amherst College in Massachusetts. An experimental quantum computer developed by D-Wave Systems was able to solve a problem 3,600 times faster than a conventional computer, the New York Times reports. Catherine McGeoch, the Beitzel Professor in Technology and Society in the computer science department at Amherst College administered the test. She...

Brett Smith for redOrbit.com - Your Universe Online As concerns over cyber security grow with each newly publicized attack, computer scientists have been pursuing quantum technology as a silver bullet against would-be hackers. According to a groundbreaking announcement, scientists at Los Alamos National Labs in New Mexico have been utilizing a small-scale “quantum internet” for the past two years. Quantum cryptography is possible because of the phenomenon known as quantum...

Synthetic Diamond Material Integral to Achieving Quantum Entanglement Between Atom-like Defects in Two Pieces of Diamond, Driving Advancements in Information Technologies and Fundamental Physics SAN FRANCISCO, May 3, 2013 /PRNewswire/ -- Element Six, the world leader in synthetic diamond supermaterials and member of the De Beers Group of Companies, today announced in collaboration with Delft University of Technology the entanglement of electron spin qubits (quantum bits) in two...

BURNABY, British Columbia and PALO ALTO, Calif., May 2, 2013 /PRNewswire/ -- D-Wave Systems Inc., the world's first commercial quantum computing company, today announced the formal launch of its U.S. business. Industry expert and supercomputing veteran, Robert "Bo" Ewald will lead the U.S. business as President and will head up global customer operations as the company's Chief Revenue Officer. New offices and R&D facilities have opened in Palo Alto, California and others are...

University of California - Santa Barbara By using light, researchers at UC Santa Barbara have manipulated the quantum state of a single atomic-sized defect in diamond –– the nitrogen-vacancy center –– in a method that not only allows for more unified control than conventional processes, but is more versatile, and opens up the possibility of exploring new solid-state quantum systems. Their results are published in the latest edition of the Proceedings of the National Academy of the...
