Indirect measurement
... POVMs tell us the probabilities of outcomes for an indirect measurement, but they don’t say what state the system is left in. It would be useful to generalize this aspect of projective measurements as well. We prepare the ancilla in state |0i and do a joint unitary Û . We then make a complete measu ...

This means that subsequent measurement of other particle (on another planet) provides the same result as the measurement of the first particle. This indicate that in quantum world non-local influences, correlations exist. Qua ...

Extending SDL and LMC Complexity Measures to Quantum States
... defined: SDL (Shiner, Davison, Landsberg) and LMC (López-Ruiz, Mancini, Calbet). SDL and LMC only differ in the way of representing thermodynamic disequilibrium and are equally useful in practical cases [11, 12, 13, 14]. The idea to be presented here is to generalize SDL and LMC measures considerin ...

Derivation of viscous correction terms for the isothermal quantum

In the classical setting, it is well-known [1] that this leads to the viscous correction to the Euler equations, i.e. to the Navier-Stokes sy ...

Bell's theorem

Bell's theorem is a ‘no-go theorem’ that draws an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. This theorem is named after John Stewart Bell.In its simplest form, Bell's theorem states:Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from ""indifference"" to ""wild extravagance"". Lawrence Berkeley particle physicist Henry Stapp declared: ""Bell's theorem is the most profound discovery of science.""Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables). Bell concluded:Bell summarized one of the least popular ways to address the theorem, superdeterminism, in a 1985 BBC Radio interview:
