Tsirelson's nonclassicality witness under dissipative dynamics
Nguyen Vu Khoi Huynh, Nicky Nel Narido Labayna, Martine Schut +1
A dynamics-based test, originally proposed by Tsirelson for the harmonic oscillator, provides a method for certifying quantumness under the assumption of a known Hamiltonian. These…
