Optomechanical Quantum Teleportation is an Important Step Toward Hybrid Quantum Internet

Researchers at the Delft University of Technology (TU Delft) in the Netherlands and the University of Campinas (UNICAMP) in Brazil have shown that information encoded in a quantum bit (qubit) consisting of a single photon can be teleported to the mechanical motion of an optomechanical device comprising billions of atoms.

Stanford Researchers Study the Quantum Properties of Soliton Microcombs

Unlike the jumble of frequencies produced by the light that surrounds us in daily life, each frequency of light in a specialized light source known as a "soliton" frequency comb oscillates in unison, generating solitary pulses with consistent timing.

Split Photons may Also Exist, Researchers Say

Nearly a century after Italian physicist Ettore Majorana laid the groundwork for the discovery that electrons could be divided into halves, researchers predict that split photons may also exist, according to a study from Dartmouth and SUNY Polytechnic Institute researchers.
