Entanglement says that 2 particles can be so inextricably connected that the state of one particle can instantly influence the state of the other, no matter how far apart they are. It will be useful for quantum computers, quantum communication networks, and high-precision quantum sensors.
Entanglement is also one of nature’s most elusive phenomena.
Producing entanglement between particles requires that they start out in a highly ordered state, which is disfavored by thermodynamics, the process that governs the i...
