Researchers at the Institute for Quantum Optics and Quantum Information (IQOQI) in Vienna recently devised a universal mechanism to invert the evolution of a qubit with a high probability of success. This protocol, outlined ...
When many quantum particles interact, complex systems can be formed. And this complexity allows reaching a temperature of absolute zero—at least in principle.
