In a newly published study, researchers from the University of Vienna detail a new model of a quantum computer, the boson sampling computer. Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the Faculty [...]

In a new study, researchers demonstrate an improvement of more than two orders of magnitude in the spin coherence time of nitrogen-vacancy centers as compared with previous measurements. The findings could advance quantum sensing, enable squeezing and many-body entanglement, and open a path to simulating driven, interaction-dominated quantum many-body Hamiltonians. From brain to heart to [...]

A newly published study details the how physicists discovered the first direct evidence of pear shaped nuclei in exotic atoms, a finding that could help explain why the Big Bang created more matter than antimatter. Ann Arbor — An international team of physicists has found the first direct evidence of pear shaped nuclei in exotic [...]

A newly published study details how a specially designed “meta-atom” of gold and silicon oxide can transmit light through a wide bandwidth and at a speed approaching infinity. In a process comparable to squeezing an elephant through a pinhole, researchers at Missouri University of Science and Technology have designed a way to engineer atoms capable [...]

UC Santa Barbara researchers developed an all-optical scheme for controlling individual quantum bits in semiconductors using pulses of light, opening up new paths toward the creation of quantum computers. Santa Barbara, California –– By using light, researchers at UC Santa Barbara have manipulated the quantum state of a single atomic-sized defect in diamond –– the [...]

In a new study, physicists from the Berkeley Lab and UC Berkeley used data from the ALPHA Experiment at CERN to measure antimatter gravity directly, presenting the first direct evidence of how atoms of antimatter interact with gravity. The atoms that make up ordinary matter fall down, so do antimatter atoms fall up? Do they [...]

A new study from the LHCb collaboration at CERN details the first observation of matter-antimatter asymmetry in the decays of the particle known as the B0s, viewing a preference for matter over antimatter known as CP-violation in the decay of neutral B0s particles. The LHCb collaboration at CERN today submitted a paper to Physical Review [...]

SuperCDMS researchers have for the first time observed a concrete hint of a weakly interacting massive particle (WIMP), the particle physicists believe to be behind dark matter. College Station — An international collaboration whose search for dark matter is powered by detectors being fabricated at Texas A&M University has for the first time observed a [...]

New research from the Max Planck Institute shows that silicon nanowires become doped with unexpectedly large amounts of aluminum during growth, increasing their conductivity and defying the laws of thermodynamics. Nanoelectronics has taken another step forward. An international team including researchers from the Max Planck Institute of Microstructure Physics in Halle has discovered an effect [...]

Using a completed section of the NOvA neutrino detector, scientists have begun collecting data from cosmic rays. What will soon be the most powerful neutrino detector in the United States has recorded its first three-dimensional images of particles. Using the first completed section of the NOvA neutrino detector, scientists have begun collecting data from cosmic [...]

Using new data from the ESA’s Planck Mission analysis of the CMB, physicist John Cramer from the University of Washington provides a new “high-fidelity” rendition of the Sound of the Big Bang. A decade ago, spurred by a question for a fifth-grade science project, University of Washington physicist John Cramer devised an audio recreation of [...]

In a newly published study, researchers detail how they used a cloud of rubidium atoms as an optical memory device, showing that portions of an image written into a gradient echo memory can be individually retrieved or erased on demand, an important step toward processing a spatially multiplexed quantum signal. Talk about storing data in [...]
