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 long-lived quantum memory (quantum […]

A team of researchers at the Institute of Laser Engineering, Osaka University, in collaboration with Bielefeld University and Technical University Braunschweig in Germany, came closer to unraveling the complicated optical response of wide-bandgap semiconductor multiple […]
The promise of a quantum internet depends on the complexities of harnessing light to transmit quantum information over fiber optic networks. A potential step forward was reported today by researchers in Sweden who developed integrated […]
Recently, Professor Jiang Ying from International Center for Quantum Materials and Research Center for Light-Element Advanced Materials of Peking University, in collaboration with Professor Jörg Wrachtrup from Stuttgart University and Professor Yang Sen from the […]
Clocks are essential building blocks of modern technology, from computers to GPS receivers. They are also essentially engines, irreversibly consuming resources in order to generate accurate ticks. But what resources have to be expended to […]
Scientists at Raytheon BBN Technologies have developed a new way to detect a single photon, or particle of light—a development with big applications for sensors, communications and exponentially more powerful quantum computer processors. Click to […]
Like conductors of a spooky symphony, researchers at the National Institute of Standards and Technology (NIST) have “entangled” two small mechanical drums and precisely measured their linked quantum properties. Entangled pairs like this might someday […]
The uncertainty principle, first introduced by Werner Heisenberg in the late 1920’s, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all electrical product can also behave […]
In an international collaboration, researchers at the University of Stuttgart were able to detect quantum bits in two-dimensional materials for the first time. Nature Materials publishes this research in its May 6, 2021 issue. Click […]
At extremely low temperatures, matter often behaves differently than in normal conditions. At temperatures only a few degrees above absolute zero (-273 degrees Celsius), physical particles may give up their independence and merge for a […]
