Quantum computing with classical bits
C. Wetterich
A bit-quantum map relates probabilistic information for Ising spins or classical bits to quantum spins or qubits. Quantum systems are subsystems of classical statistical systems. T…
Quantum particles from coarse grained classical probabilities in phase space
C. Wetterich
Quantum particles can be obtained from a classical probability distribution in phase space by a suitable coarse graining, whereby simultaneous classical information about position…
Quantum particles from classical probabilities in phase space
C. Wetterich
Quantum particles in a potential are described by classical statistical probabilities. We formulate a basic time evolution law for the probability distribution of classical positio…
Zwitters: particles between quantum and classical
C. Wetterich
We describe both quantum particles and classical particles in terms of a classical statistical ensemble, characterized by a probability distribution in phase space. By use of a wav…
Quantum mechanics from classical statistics
C. Wetterich
Quantum mechanics can emerge from classical statistics. A typical quantum system describes an isolated subsystem of a classical statistical ensemble with infinitely many classical…
Probabilistic observables, conditional correlations, and quantum physics
C. Wetterich
We discuss the classical statistics of isolated subsystems. Only a small part of the information contained in the classical probability distribution for the subsystem and its envir…
