Quantum computers, quantum cryptography and quantum (insert name here) are often in the news these days. Articles about them inevitably refer to entanglement, a property of quantum physics that makes all these magical phenomena possible. Untangling quantum entanglement Einstein called entanglement “spooky action at a distance,” a name that has stuck and become increasingly popular. … Continue reading What is quantum entanglement?
