On Entanglement with Vacuum
Marcin Pawlowski, Marek Czachor
The so-called entanglement with vacuum is not a property of the Fock space, but of some rather pathological representations of CCR/CAR algebras. In some other Fock space representa…
Quantum optics in different representations of the algebra of canonical commutation relations (I): Unexpected properties of Rabi oscillations -- theory and experiment
Marcin Wilczewski, Marek Czachor
We discuss the Jaynes-Cummings model in different representations of the algebra of canonical commutation relations. The first conclusion is that all the irreducible representation…
The fundamental problem of quantum cryptography
Marcin Pawlowski, Marek Czachor
It is known that statistical predictions of quantum theory do not depend on its interpretation. In particular, an experiment cannot distinguish between the Copenhagen interpretatio…
