Spin and Quantum Computers

One day I am sure that physics will view Nature as real. Throughout history initial ideas of non-local effects, also called “action-at-a-distance”, have been repudiated and replaced with something more physically reasonable. The most well-known examples are the early attempts to understand gravity and electromagnetism. So it will be with non-locality between entangled particles.

The Bloch Sphere and Spin in Quantum Mechanics

This complementary nature of states with non-commuting operators, (σX, σY ,σZ), is the basis for the Copenhagen Interpretation of Quantum Mechanics (CI). It states, basically, that if the Z states exist then the X do not, and vice versa. I would rather conclude that it is impossible to determine experimentally if spin has more than one axis of quantization.
