Beyond six nines: Ultra-enriched silicon paves the road to quantum computing
(Phys.org) —Using a relatively straightforward technique, a team of NIST researchers has created what may be the most highly enriched silicon currently being produced. The material is more than 99.9999% ...
Does probability come from quantum physics?
(Phys.org)—Ever since Austrian scientist Erwin Schrodinger put his unfortunate cat in a box, his fellow physicists have been using something called quantum theory to explain and understand the nature of waves and particles.
Study finds weird magic ingredient for quantum computing
A form of quantum weirdness is a key ingredient for building quantum computers according to new research from a team at the University of Waterloo's Institute for Quantum Computing (IQC).
Remote quantum applications, teleportation enabled by calling long distance between superconducting qubits
(Phys.org) —Researchers have developed a way for superconducting quantum chips to talk to each other over large distances through an optical fibre, allowing quantum entanglement or teleportation - both ...
Physicist disentangles 'Schrodinger's cat' debate
Physicist Art Hobson has offered a solution, within the framework of standard quantum physics, to the long-running debate about the nature of quantum measurement.
Never mind the noise: Quantum entanglement allows channel information rate to exceed Shannon zero-error capacity
Physicists succeed in closing last local realistic loophole for systems of entangled photons
A team led by the Austrian physicist Anton Zeilinger has carried out an experiment with photons, in which they have closed an important loophole. The researchers have thus provided the most complete experimental ...
Physicists correct quantum errors
Scientists from the FOM Foundation and the Technical University Delft, working together at the Kavli Institute of Nanoscience, have succeeded in detecting and correcting errors during the storage of quantum ...
Atoms and molecules on the same wavelength
(Phys.org) —It may be surprising, but in physics the terrain of atoms and the territory of organic molecules are worlds apart. Therefore, in order to have a molecule communicate optically with atoms, the ...
Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
Quantum physics in 1-D: New experiment supports long-predicted 'Luttinger liquid' model
How would electrons behave if confined to a wire so slender they could pass through it only in single-file?
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 ...
Researchers confirm 60-year-old prediction of atomic behavior
Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.
New analysis eliminates a potential speed bump in quantum computing
A quantum particle can search for an item in an unsorted "database" by jumping from one item to another in superposition, and it does so faster than a classical computer ever could.
