Review Letters. “It’s really just this [one aspect] that needs to be updated.” In its most famous articulation, Heisenberg’s uncertainty principle states that it’s possible at a given moment to know either the position or momentum of a particle, but not both. This relationship can be written out mat ...

Many problems that take long time to solve on a deterministic Turing
... solve on a deterministic Turing machine can be often be solved very quickly on a probabilistic Turing machine However there is a tradeoff between the time it takes to return an answer to a computation and the probability that the returned answer is correct ...

... •The operator H is the hamiltonian or the total energy operator and is the sum of the kinetic energy operator and the potential energy operator. As explained earlier this can be done by writing the classical expression of the Hamiltonian and then replacing the position and momentum variables by thei ...

Inequivalence of pure state ensembles for open quantum systems
... is often possible to approximate the evolution of such systems by a Markovian master equation ρ̂˙ = Lρ̂, where L is the Lindbladian [3]. Under these conditions, an experimenter may perform continual measurements on the environment with which the system interacts without affecting the master equation ...
