A Columbia University team announced that they have discovered a new way to control the phase of light using 2D materials — atomically thin materials, ~0.8 nanometer, or 1/100000 the size of a human hair — without […]
Cambridge Quantum Computing announced a collaboration with CERN Openlab, named the QUATERNION project, in quantum computing.
At Fermilab and Argonne National Laboratory, researchers work to determine whether instruments called superconducting radio-frequency cavities, also used in particle accelerators, can solve one of the biggest problems facing the successful development of a quantum […]
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo report the first occurrence of directly splitting one photon into three. The occurrence, the first of its kind, used the spontaneous parametric […]
Researchers have been able to demonstrate how a quantum system measurement lasts only a millionth of a second.
Accurate control of quantum systems requires a precise measurement of the parameters that govern the dynamics, including control fields and interactions with the environment. Parameters will drift in time and experiments interleave protocols that perform […]
Researchers from Argonne National Laboratory and the University of Chicago entangled photons across a 52-mile network in Chicago. The quantum loop is among the longest land-based quantum networks in USA. Argonne plans to scale this network by […]
University of Dayton researchers became the first to create a new “state of light” and showed it also can rotate around a transverse axis perpendicular to the direction light travels, like a cyclone. This new […]
Researchers at Nanyang Technological University, Singapore, have presented a complete theoretical scheme of quantum computing with exciton-polariton condensates formed in semiconductor micropillars. Exciton-polariton condensates have attractive features for quantum computation, e.g., room temperature operation, high […]
Researchers are investigating light-emitting defects in materials that may someday form the basis of quantum-based technologies, such as quantum computers, quantum networks or engines that run on light. Once understood, these defects can become controllable […]
Massive-scale particle physics produces correspondingly large amounts of data and this is particularly true of the Large Hadron Collider (LHC), the world’s largest particle accelerator, which is housed at the European Organization for Nuclear Research […]
A practical way to link separate nodes in quantum networks is to send photons over the standard telecom fibre network. This requires sub-Poissonian photon sources in the wavelength band around 1550 nm, with photon coherence times […]
The ALPHA collaboration at CERN has reported the first measurements of certain quantum effects in the energy structure of antihydrogen, the antimatter counterpart of hydrogen. These quantum effects are known to exist in matter, and […]
