Two aspects of quantum mechanics that are not understood are non-locality and the persistence of entanglement to space-like separations. In this part entanglement is explained and non-locality is shown to be a concept that no-one understands. Non-locality is called quantum weirdness.

In this part of the seminar it is pointed out that quantum mechanics is a theory of measurement of the microscopic. This means that a probe of some sort must be used to "see" spin. However it is pointed out that states exist in the completely isotropic environment in the absence of a probe.

The longest standing unsolved problem in quantum mechanics is the EPR paradox. Its history is traced from the 1927 Solvay Conference to the present time. Today non-locality is firmly entrenched in physics and in spite of various experiments on teleportation, quantum cryptography and quantum computing, no one understands now entanglement persists to space like separation.

Local realism is heresy

Since there is no experimental way to confirm that two axes exist, rather than one, the choice between local realism and non-local indeterminism is subjective. Since non-locality is the basis of “quantum weirdness”, Occam’s razor takes the side of locality.

....rather than showing the consistency of the 2D spin with the CHSH equation, we show the CHSH equation predicts the hidden spin. That is starting with the CHSH form of Bell’s Inequalities, a vector of length √2 is found that maximizes the CHSH equation: the 2D spin is hidden inside the CHSH equation.

I have been saying in my blogs that if spin has two axes of quantization, then all the quantum weirdness dissolves and the EPR paradox is reconciled. This is not some new change or addition to quantum mechanics, and there is nothing classical about it. The only deviation from the usual application of quantum mechanics is that a single spin is isolated and there is no measuring probe. That is, space is isotropic. So the only conceptual change I am making is the following:
Quantum mechanics is a theory of measurement, but not of Nature, and can be extended to states that exist beyond our ability to measure.

In both cases to detect a spin a probe must be used. The picture that emerges of spin is the well-known point particle having a single axis of quantization, defined by the orientation of the probe field. What happens when the probe is removed?

Intuition tells us that if we improve detection efficiency and build better experiments the number of detected events will increase until, at 100% efficiency, Fair Sampling would be verified because all events would be recorded. This fails, however, to take into account the Heisenberg Uncertainty Principle. Fair Sampling is always valid for classical events but not always valid for quantum events.

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 Heisenberg Uncertainty Principle does more than restrict what we can measure, it also result in us missing properties that are actually present.

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.
