Quantum entanglement is a process through which two particles become entangled and remain connected over time, even when separated by large distances. Detecting this phenomenon is of crucial importance for both the development ...
Scientists made headlines last week for supposedly generating a wormhole. The research, reported in Nature, involves the use of a quantum computer to simulate a wormhole in a simplified model of physics.
