Scientists score one more victory over uncertainty in quantum physics measurements
(PhysOrg.com) -- Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider ...
High-power, 532 nm-wavelength compact green laser module with high efficiency, high-speed modulation capability
QD Laser, Inc., the Institute for Nano Quantum Information Electronics, the University of Tokyo, and Fujitsu Laboratories Limited today announced the successful development of a high-power 532 nm-wavelength ...
Are you certain, Mr. Heisenberg? New measurements deepen understanding of quantum uncertainty
Heisenberg's Uncertainty principle is arguably one of the most famous foundations of quantum physics. It says that not all properties of a quantum particle can be measured with unlimited accuracy. Until now, this has often ...
Quantum computing has applications in magnetic imaging
Quantum computing -- considered the powerhouse of computational tasks -- may have applications in areas outside of pure electronics, according to a University of Pittsburgh researcher and his collaborators.
U of Toronto experiment named top breakthrough of 2011 by Physics World
Aephraim Steinberg and colleagues at the Centre for Quantum Information and Quantum Control at the University of Toronto had the top physics breakthrough of the year according to Physics World magazine.
Adding up photons with a transition edge sensor
(PhysOrg.com) -- Scientists have demonstrated that a superconducting detector called a transition edge sensor (TES) is capable of counting the number of as many as 1,000 photons in a single pulse of light ...
Kilogramme faces quantum diet after weight problem
The guardians of the world's most important standards of weights and measures have turned to the weird universe of quantum physics to try to resolve a dilemma.
Redefining the kilogram and the ampere
New research using graphene presents the most precise measurements of the quantum Hall effect ever made, one of the key steps in the process to redefine two SI units.
Is graphene the best quantum resistance standard?
New research from NPL's Quantum Detection Group presents the most precise measurements of the quantum Hall effect ever made, using the two-dimensional material graphene.
All-optical quantum computation, step 1: A controlled-NOT photonic gate
Canadian researchers devise method to directly measure the quantum wavefunction
Quantum physics first: Researchers observe single photons in two-slit interferometer experiment
Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And ...
Sensitivity of precision measurements enhanced by the environment
Weighty mission for scientists: redefine the kilo
Scientists said Monday they were moving closer to coming up with a non-physical definition of the kilo after discovering the metal artefact used as the international standard had shed a little weight.
