Does anyone know what “Quantum Computing” is?

Question

In physics, its the ability for particles to exist in multiple/parallel dynamic states at a particular point in time. In computing, would it be the ability of a data bit to

Answer 1

The other factor where the word "quantum" computing is used regards an "entangled pair". Essentially if you can create an entangled pair of particles which have a physical "spin", quantum physics dictates that the spin on each electron will always be opposite.

If you could create an entangled pair and then separate them, you could use the device to transmit data without interception, by changing the spin on one of the particles. You can then create a signal which is modulated by the particle's information which is theoretically unbreakable, as you cannot know what spin was on the particles at any given time by intercepting the information in between the two signal points.

A whole lot of very interested organisations are researching this technique for secure communications.
