Is every quantum measurement reducible to measurements of position and time?
I am currently studying Path Integrals and was unable to resolve the following problem. In the famous book Quantum Mechanics and Path Integrals, written by Feynman and Hibbs, it says (at the beginning ...

Determinism, classical probabilities, and/or quantum mechanics?
[I]f you want a universe with certain very generic properties, you seem forced to one of three choices: (1) determinism, (2) classical probabilities, or (3) quantum mechanics. [My emphasis.]

Quantum superposition and fate
First of all, sorry for my knowledge of physics. Maybe my question is too obvious but I want to ask it.
I am thinking about fate and if it exist or no.
According to my assumption if I take any ...

Is the preferred basis problem solved?
Once and for all: Is the preferred basis problem in the Everettian Interpretation of QM considered solved by decoherence or not?
THere are a few people who claim that it's not, but it seems the vast ...

Does it make sense to speak of amplitudes of finite closed boundaries in QFT?
A example of amplitude in Relativistic Quantum Mechanics or specifically in QFT is the amplitude of a field configuration on a space-like hyper-surface of space-time to "lead" to another field ...

Does the extended probability ensemble interpretation of quantum mechanics make any sense?
Gell-Mann and Hartle came up with the extended probability ensemble interpretation over here.
Basically, they extended probability theory to include real numbers which may be negative or greater than ...

Why should multiple versions of a weak measurement preclude it from being a measurement of intrinsic properties of some system
I've been trying to understand Stephen Parrott's criticisms of weak measurement, outlined most concisely here: http://arxiv.org/abs/0909.0295
One of his major criticisms is that weak measurement is ...

Are there any connections between James–Stein estimator and quantum mechanics?
Very nice statement from wiki:
When three or more unrelated parameters are measured, their total MSE can be reduced by using a combined estimator such as the James–Stein estimator; whereas when ...
