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…
And what if Bohm was right? The fundamental problem of quantum cryptography and a way to circumvent it
Marek Czachor, Marcin Pawlowski
This paper has been withdrawn. The main technical result will reappear in the new version of quant-ph/0501003.
Comment on "Quantum entropy and special relativity" [by A. Peres, P. F. Scudo, and D. R. Terno, Phys. Rev. Lett. 88, 230402 (2002)]
Marek Czachor
Two subtleties of this paper are discussed.
Reducible field quantization (II): Electrons
Marek Czachor
Quantization of free Dirac fields is formulated in terms of a reducible representation of CAR. Similarly to the bosonic case we arrive at field operators which are indeed operators…
