(Phys.org)—Physicists have implemented the first experimental demonstration of everlasting quantum coherence—the phenomenon that occurs when a quantum system exists in a superposition of two or more states at once. Typically, ...
One of the main principles of quantum physics is the superposition of states. Systems exist simultaneously in different states until they are measured and the system opts for one of the possibilities. As long as the superposition ...
