Rethinking Collapse: Coupling Quantum States to Classical Bits with quasi-probabilities
Dagomir Kaszlikowski, Pawel Kurzynski
We propose a formulation of quantum measurement within a modified framework of frames, in which a quantum system - a single qubit - is directly coupled to a classical measurement b…
Quasi-probabilistic Bit Erasure Causes Bell Non-locality
Kelvin Onggadinata, Pawel Kurzynski, Dagomir Kaszlikowski
We show that a maximal violation of the Bell-CHSH inequality for two entangled qubits, i.e., Bell non-locality, is a direct consequence of a local bit erasure by means of a quasi-s…
Trade-off relations between Bell nonlocality and local Kochen-Specker contextuality in generalized Bell scenarios
Lucas E. A. Porto, Gabriel Ruffolo, Rafael Rabelo +2
The relations between Bell nonlocality and Kochen-Specker contextuality have been subject of research from many different perspectives in the last decades. Recently, some interesti…
Communication Cost in Simulating Unknown Entangled States
Kelvin Onggadinata, Pawel Kurzynski, Dagomir Kaszlikowski
We demonstrate how to universally simulate ensemble statistics of projective local measurements on any -qubit state shared among observers with classical communication and s…
Non-classicality Primitive in a Quasi-probabilistic Toy Model
Kelvin Onggadinata, Pawel Kurzynski, Dagomir Kaszlikowski
We demonstrate a basic non-classical effect in a quasi-probabilistic toy model with local Alice and Bob who share classical randomness. Our scenario differs from the orthodox demon…
Operational approach to bilocality with joint probability distributions
Kelvin Onggadinata, Pawel Kurzynski, Dagomir Kaszlikowski
We show an operational approach to bilocality with quasi-probability distributions and quasi-stochastic processes. This approach clearly demonstrates that negative probabilities ar…
