Cryptographic security of the quantum key distribution from the triangle inequality
Pawel Kurzynski, Marcin Markiewicz, Dagomir Kaszlikowski
We show that the Csiszar-Korner sufficient condition for secure cryptographic key generation with the help of quantum theory can be easily derived using the triangle inequality for…
On compression of non-classically correlated bit strings
Pawel Kurzynski, Marcin Markiewicz, Dagomir Kaszlikowski
In this short note we present a new approach to non-classical correlations that is based on the compression rates for bit strings generated by Alice and Bob. We use normalised comp…
The triangle principle: a new approach to non-contextuality and local realism
Pawel Kurzynski, Dagomir Kaszlikowski
In this paper we study an application of an information distance between two measurements to the problem of non-contextuality and local realism. We postulate the triangle principle…
Coherent states of composite bosons
Su-Yong Lee, Jayne Thompson, Pawel Kurzynski +2
We present a systematic analysis on coherent states of composite bosons consisting of two distinguishable particles. By defining an effective composite boson (coboson) annihilation…
Fundamental monogamy relation between contextuality and nonlocality
Pawel Kurzynski, Adan Cabello, Dagomir Kaszlikowski
We show that the no-disturbance principle imposes a tradeoff between locally contextual correlations violating the Klyachko-Can-Binicioglu-Shumovski inequality and spatially separa…
Contextuality in bosonic bunching
Pawel Kurzynski, Akihito Soeda, Jayne Thompson +1
We show that under certain assumptions one can derive a variant of Specker's non-contextual inequality for a system of three indistinguishable bosonic particles. The inequality sta…
