This work demonstrates a new toolbox for the analysis of neutron scattering data and might foster a deeper understanding of quantum materials that are relevant for technological use.

A Russian research group at the Moscow Institute of Physics and Technology has demonstrated a superconductor feature known as Abrikosov vortices exists in non-superconducting metal when in contact with a superconductor. The nexus for quantum computers and this finding lays in the key property of superconductors: Quantum coherence. This “macroscopic quantum coherence of superconductors” may be harnessed to enable qubits.
University of Rochester researchers have published a list of ’12 Herculean tasks’ they believe will inspire the next quantum scientists. One of the authors demonstrated the use of ‘twisted light’ to slightly more than double data-throughput per photon. The approach utilized the mechanics of orbital angular momentum (OAM) of photons for encoding the data. Two of the tasks put forth to ponder are, “What is the future of quantum coherence, squeezing, and entanglement for enhanced super resolution and sensing?”, “How can we solve some of humanity’s biggest problems through new quantum technologies?”
