Measurement-induced asymmetry in bipartite networks

We consider an interacting bipartite network through a Bayesian game-theoretic framework and demonstrate that weak measurements introduce an inherent asymmetry that is not present when using standard projective measurements. These asymmetries are revealed in the expected payoff for a Bayesian version of the Prisoner's dilemma , demonstrating that certain advantages can be found for given subsystems depending on the measurements performed in the network. We demonstrate that this setup allows measurement-induced control for one of the respective parties. • Weak measurements allow a different level of control. • Measurement theory induces asymmetry in game-theoretic networks. • Asymmetry is observed in quantum correlation beyond entanglement. • A Bayesian version of the Prisoner's dilemma is introduced.

Abstract

We consider an interacting bipartite network through a Bayesian game-theoretic framework and demonstrate that weak measurements introduce an inherent asymmetry that is not present when using standard projective measurements. These asymmetries are revealed in the expected payoff for a Bayesian version of the Prisoner's dilemma , demonstrating that certain advantages can be found for given subsystems depending on the measurements performed in the network. We demonstrate that this setup allows measurement-induced control for one of the respective parties. • Weak measurements allow a different level of control. • Measurement theory induces asymmetry in game-theoretic networks. • Asymmetry is observed in quantum correlation beyond entanglement. • A Bayesian version of the Prisoner's dilemma is introduced.
