Scientists Discover a Second Law for Quantum Entanglement
Entanglement has now become the key resource in quantum information theory. It is being used in quantum teleportation and quantum cryptography, quantum computing, communication, and precision measurements. More than 200 years after Sadi Carnot introduced the second law of thermodynamics, scientists have discovered a similar rule for the quantum world. This new “second law of entanglement” demonstrates that quantum entanglement can be altered and reversed in a controlled manner, much like the...
