First Things First: The Physics of Causality
Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

Gravity's Residue
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Already Rafael Bombelli (1526-1573) understood that any complex number occurs together with its conjugate (suo Residuo), cf. Helmut Gericke, Geschichte des Zahlbegriffs. Accordingly, a complex representation of a real world quantity is redundant. It does not convey more information as compared with the seemingly poorer real-valued one. I will reconsider this as soon as the first quantum computer shows its claimed superiority.

"How much information is really there in a quantum state?"

And how does one go about counting or accounting it?

How far back into the past does a Quantum State remain intact, what memory of a previous state does a Q-bit have/retain?

To possibly be in "Two Places at Once", one really has to define "place" , what here is meant place? this the same as being in "two space's" at one instant of time? thus a particle can be in ANY two location of the future, or ANY two...

This is an interesting topic but the basic idea is due to the quantum superposition. Recently it was realized that macroscopic systems (computers are also macroscopic devices) will obey a nonlinear Schrodinger equation (see for instance arXiv:0711.1442 attached bellow). Hence, the superposition principle is no more valid.
