The Dirac matrices do not answer the question, they are for Minkowski space, 3 dimensions of space and 1 of time, not the 4 spatial dimensions that are at issue. The question is a deeper one than it appears. For position and momentum only 2 conjugate bases are assumed, connected by a Fourier...

When we last left our heroes... Now let's consider two photons, 1 & 2, both in an equally weighted superposition of polarization. Their states are \Psi_1=\frac{1}{\sqrt2}\{|H>_1+|V>_1\} and \Psi_2=\frac{1}{\sqrt2}\{|H>_2+|V>_2\} When the two particles are independent, when a measurement...

Thanks. \Psi^{P60}_1=\frac{1}{\sqrt2}\{|h\uparrow>+|v\downarrow>\} B=\left[\begin{array}{cc}1&0\\0&1\end{array}\right] OK, that should get us started. The current topic of this thread is whether or not the wave function collapses. Let's start with the simpler question of whether it changes...

This has been a fun thread but it occurs to me that our discussion is handicapped by our notation, plain English text. Does the physics forum support equations? We could then give clear examples in Dirac notation of the various superposition, entangled & collapsed states. Does anyone know how...

Actually, this is exactly what physics claims. The implication of Bell's inequality is that collapse not only happens but that no common cause can account for it. The challenge in spacelike separated entanglements is to explain the correlations. Consider a series of experiments where a...

QTP - The Anomalies in CQM In my first post I presented several lines of evidence that spacelike causality may be allowed in physics. Each was presented, briefly, and without justification. Ken G took issue with item number 3, the 5 anomalies of classical quantum mechanics (CQM), so I'll...

To Ken G. Thank you for taking the time to comment. It is a little late here, so I'll respond in full to selected comments tomorrow. This blog prevents posting URL's until at least 15 posts have been made, a rule I presume exists to keep spam to a minimum, but you should have no trouble finding...

Quantum Temporal Paradox There are indications that despite the Grandfather Paradox and Eberhard's proof to the contrary, quantum nonlocality may in fact support FTL. The lines of evidence are as follows; 1. Teleportation does in fact transmit information, since the state of the particle...
