New Method To Distinguish Between Neighboring Quantum Bits
2013-06-18 09:01:59

University of New South Wales Researchers at the University of New South Wales have proposed a new way to distinguish between quantum bits that are placed only a few nanometers apart in a silicon chip, taking them a step closer to the construction of a large-scale quantum computer. Quantum bits, or qubits, are the basic building blocks of quantum computers - ultra-powerful devices that will offer enormous advantages for solving complex problems. Professor Michelle Simmons, leader of...

New Quantum Technologies Enabled With Spintronics Approach
2013-06-04 16:20:51

University of Chicago A team of researchers, including members of the University of Chicago´s Institute for Molecular Engineering, highlight the power of emerging quantum technologies in two recent papers published in the Proceedings of the National Academy of Sciences. These technologies exploit quantum mechanics, the physics that dominates the atomic world, to perform disparate tasks such as nanoscale temperature measurement and processing quantum information with lasers. The two...

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...

Quantum Supercomputing Facility Brings NASA And Google Together

redOrbit Staff & Wire Reports - Your Universe Online Google and NASA are joining forces to create a new research laboratory that will use a quantum supercomputer to study artificial intelligence and machine learning, according to various media reports. The Mountain View, California-based computing company and the US space agency´s new Quantum Artificial Intelligence Lab will be hosted at the Ames Research Center in California and will include a quantum supercomputer supplied by...

Brighter Future From Photonic Quantum Computers
2013-05-13 12:40:14

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...

Researchers Extend Electron Spin In Diamond For Incredibly Tiny Magnetic Detectors
2013-05-10 10:18:01

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...

D-Wave Quantum Computer Passes Important Computing Test
2013-05-09 17:57:32

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....


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
