What is quantum entanglement?

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?

Wiring quantum computers

Physicists from Japan and Australia have proposed a novel two-dimensional design for a quantum computer that can be constructed using existing integrated circuit technology.  Their work is explained in the video below. The full paper can be found in the New Journal of Physics. Credit: Tokyo University of Science, Japan The research was led by Tokyo … Continue reading Wiring quantum computers
