From Classical Mechanics with Doubled Degrees of Freedom to Quantum Field Theory for Nonconservative System
Y. Kuwahara, Y. Nakamura, Y. Yamanaka
The -matrix structure of Green's functions is a common feature for the real-time formalisms of quantum field theory under thermal situations, such as the closed time pa…
Determining eigenvalues of a density matrix with minimal information in a single experimental setting
Tohru Tanaka, Yukihiro Ota, Mitsunori Kanazawa +3
Eigenvalues of a density matrix characterize well the quantum state's properties, such as coherence and entanglement. We propose a simple method to determine all the eigenvalues of…
Non-Abelian Phases from a Quantum Zeno Dynamics
Daniel Burgarth, Paolo Facchi, Vittorio Giovannetti +3
A connection is estabilished between the non-Abelian phases obtained via adiabatic driving and those acquired via a quantum Zeno dynamics induced by repeated projective measurement…
Entropy-Driven Phase Transitions of Entanglement
Paolo Facchi, Giuseppe Florio, Giorgio Parisi +2
We study the behavior of bipartite entanglement at fixed von Neumann entropy. We look at the distribution of the entanglement spectrum, that is the eigenvalues of the reduced densi…
