Aalto University Researchers Observe Long-Lived, Macroscopic Quantum Entanglement
Evading the uncertainty principle in quantum physics In quantum mechanics, the Heisenberg uncertainty principle dictates that the position and speed of an object cannot both fully be known precisely at the same time. In a study published this week in Science, researchers show that two vibrating drumheads, the size of a human hair, can be […]
Visualizing Excitons, Confirming Heisenberg’s Uncertainty Principle, OIST Research Pushes Quantum Technology
Scientists capture first ever image of an electron’s orbit within an exciton In a world-first, researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have captured an image showing the internal orbits, or spatial distribution, of particles in an exciton – a goal that had eluded scientists for almost a century. Excitons […]
China Claim: 1h Coherence and 96.4% Fidelity for Optical Quantum Memory
Researchers realize coherent storage of light over one hour Read More… Energy level diagram and experimental setup. (Image Credit: MA Yu et al.) + Remote quantum distribution on the ground is limited because of the loss of photons in optical fibers. One solution for remote quantum communication lies in quantum memories: photons are stored in […]

BNL Research Into Topological Superconductors Pulls Quantum Computing Closer
Mapping the Electronic States in an Exotic Superconductor Scientists characterized how these states depend on local chemical composition, narrowing the search for where to look compositionally to enable quantum computing (Left) Through neutron scattering experiments, scientists observed distinct patterns of magnetic correlations in superconducting (“single-stripe magnetism”) and nonsuperconducting (“double-stripe magnetism”) samples of a compound containing […]
Superconducting Qubits and Microwave Photons: A Step to Long-Life Quantum Memory?
NUST MISIS Scientists Got Photons to Interact, Taking Step Towards Long-Living Quantum Memory An international research team, obtained experimental evidence for effective interaction between microwave photons via superconductive qubits for the first time. The study, published in npj Quantum Materials, may be a step towards the implementation of a long-living quantum memory and the development of […]
CCNY Feat is First Step Towards Realizing Scalable Single Photon Switches on a Chip
CCNY team makes single photon switch advance Schematic of the optical microcavity with 2D semiconductor. The nonlinear optical response arises from the larger Bohr radii Rydberg excitons allowing to push the limit to few photon nonlinear limit. Image credit: Rezlind Bushati. The ability to turn on and off a physical process with just one photon […]
Some Say Quantum Is Coming, Some Have Doubts
The State of Quantum Computing Read More… + …The Chinese team used quantum computing to achieve the calculation in a few minutes. + “[This] is certainly an impressive academic achievement, showing that quantum machinery can in some cases strain the abilities of conventional computers,” said Chris Monroe, co-founder and chief scientist of IonQ, a quantum […]
Shadow: Majorana Fermion Controversy Calls Into Question Much About Science
Quantum computing’s reproducibility crisis: Majorana fermions We’ll let you decide. Well worth the read from the source, below. Because Quantum is Coming. Qubit. Read More… + Much is at stake. Majorana particles are in theory their own antiparticles, and were predicted in 1937 by Italian physicist Ettore Majorana. Computer giant Microsoft hopes to use Majorana […]
