Quantum tunneling and stochastic resonance - Physik Uni
... the role of quantum fluctuations has only started to be explored. We study SR in the temperature range where quantum tunneling corrections to the classical rate of activation are relevant. For a particle subject to moderateto-large friction, we show that the semiclassical SR can be enhanced consider ...

A mechanistic classical laboratory situation violating the Bell
... measurement of the momenta of the individual particles gives us correlated results. These correlations were however already present before the coincidence measurement. The measurement only detects the correlations and does not create them. These kinds of correlations can never be used to violate Bel ...

This separation of charges establishes an electric field that opposes further charge build-up. As long as charges fl ...

Quantum factorization of 56153 with only 4 qubits
... et al. [1] in 2012 factored an entire class of numbers, and not just the one number that they reported (which was 143). The largest such number that we found without using any prior knowledge of the solution to the factorization problem was 56153. Since the experiment in [1] only involved 4 qubits, ...
