Classical limit and quantum logic - Philsci
... In the foundations of physics, the quest of explaining how the laws of classical mechanics arise from the laws of quantum mechanics is known as the classical limit problem (Cohen 1989). Generally, this limit is studied for systems that, due to its interaction with the environment, develop a process ...

Control of quantum systems using model
... challenges since quantum measurements tend to destroy the state of the system (wave packet reduction) [24, 25]. Nevertheless, the possibility of continuous monitoring and manipulation on the natural time-scale has recently become realistic for some quantum systems [26, 27, 28]. This may be viewed as ...

Quantum Computation - School of Computing Science
... Specifying Correctness of Teleportation We defined Teleport(a,b), which receives a qubit on channel a and sends a qubit on channel b, using teleportation in between. The following process has the same effect, and we regard it as a specification of teleportation. Identity(a,b) = a?[x] . b![x] . Stop ...

... at hand, a system in an eigenstate of the total spin operator with eigenvalue 0, this means that a measurement of the total spin will have the outcome 0 with probability 1. In this special case, in which the outcome is certain (probability 1), it is plausible and harmless to think that the total sys ...

De Broglie-Bohm Theory: A Hidden Variables Approach to Quantum
... First discovered by Louis de Broglie in 1927 [1] and later rediscovered by David Bohm in 1952 [2], de Broglie-Bohm Theory is a description of nonrelativistic quantum mechanics that introduces particle positions as hidden variables. The wavefunction of a system of particles, with it’s time evolution ...

Copenhagen interpretation From Wikipedia, the free encyclopedia
... All this familiar story is true, but it leaves out an irony. Bohr's version of quantum mechanics was deeply flawed, but not for the reason Einstein thought. The Copenhagen interpretation describes what happens when an observer makes a measurement, but the observer and the act of measurement are them ...
