Visualizing the Difference Between a Superposition and a Mixture
... state; it is an example of classical ignorance. An equivalent way to describe the difference between a superposition and a mixture, is to say that to calculate the probability of measurement outcomes for a superpostion you add the probability amplitudes and square the sum. For a mixture you square th ...

Information Loss
... known. It seems to me that there is plenty of room for nuances in the dictionary when black holes are present that would allow the late time observable correspondence to fail. Put another way, why can’t the CFT state at late times continue to encode the information that went into a black hole, even ...

Two-State Vector Formalism
... Here, the measurements of the spin in components in any direction yield the same result for both particles. There is no pre-selected quantum system with such property. The TSVF is a time symmetric approach. However, there are some differences between forward and backward evolving quantum states: we ...
