Physicists have developed a quantum simulation method that can "virtually cool" an experimental quantum system to a fraction of its actual temperature. The method could potentially allow access to extremely low-temperature ...
(Phys.org)—Scientists have discovered an anomaly in the properties of ice at very cold temperatures near 20 K, which they believe can be explained by the quantum tunneling of multiple protons simultaneously. The finding ...
The quantum internet promises absolutely tap-proof communication and powerful distributed sensor networks for new science and technology. However, because quantum information cannot be copied, it is not possible to send this ...
