Degree of entanglement as a physically ill-posed problem: The case of entanglement with vacuum
Marcin Pawlowski, Marek Czachor
We analyze an example of a photon in superposition of different modes, and ask what is the degree of their entanglement with vacuum. The problem turns out to be ill-posed since we…

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…

Entangled-state cryptographic protocol that remains secure even if nonlocal hidden variables exist and can be measured with arbitrary precision
Diederik Aerts, Marek Czachor, Marcin Pawlowski
Standard quantum cryptographic protocols are not secure if one assumes that nonlocal hidden variables exist and can be measured with arbitrary precision. The security can be restor…
