'One real mystery of quantum mechanics': Physicists devise new experiment
What is light made of: waves or particles? This basic question has fascinated physicists since the early days of science. Quantum mechanics predicts that photons, particles of light, are both particles and waves simultaneously. ...
Breakthrough in quantum computing: Resisting 'quantum bug'
Scientists have taken the next major step toward quantum computing, which will use quantum mechanics to revolutionize the way information is processed.
Quantum engines must break down
Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from University College London (UCL) and the University of Gdańsk. The ...
Google Collaborates with D-Wave on Possible Quantum Image Search
Student creates world's largest quantum cluster
(Phys.org) —Australian National University PhD student Seiji Armstrong has made a quantum leap towards next-generation computing.
Quantum engineers remove roadblock in developing next-generation technologies
(PhysOrg.com) -- An international team has removed a major obstacle to engineer quantum systems that will play a key role in the computers, communication networks, and even biomedical devices of the future.
New scheme for quantum computing
(Phys.org) —Tom Wong, a graduate student in physics and David Meyer, professor of mathematics at the University of California, San Diego, have proposed a new algorithm for quantum computing, that will speed ...
Proposed experiment offers new way to generate macroscopic entanglement
Proposed modular quantum computer architecture offers scalability to large numbers of qubits
How do you build a universal quantum computer? Turns out, this question was addressed by theoretical physicists about 15 years ago. The answer was laid out in a research paper and has become known as the ...
Two papers investigate the thermodynamics of quantum systems
Physicists discover atomic clock can simulate quantum magnetism
Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system.
Strings attached to future high temperature superconductivity
The behaviour of strongly correlated electron systems, such as high temperature superconductors, defies explanation in the language of ordinary quantum theory. A seemingly unrelated area of physics, string theory, might give ...
Effects of 'strong coupling' observed for the first time between light and a micromechanical object
(PhysOrg.com) -- Physicists at the Institute for Quantum Optics and Quantum Information (IQOQI) in Vienna and Innsbruck, Austria, have created an interaction between light and a micromechanical resonator that ...
Physicsts reveal how to cope with 'frustration'
For most people, frustration is a condition to be avoided. But for scientists studying certain "frustrated" ensembles of interacting components - that is, those which cannot settle into a state that minimizes ...
