Repeatedly readable state, spontaneous collapse, and quantum/classical boundary

Xiao-Fu Peng, Yu-Hang Luo, Jiang Zhu +5

We propose a model to identify the quantum/classical boundary. The model introduces a spontaneous collapse of state superposition: $\frac{d}{dt} ρ_{ij} =-\frac{i}{\hbar}[H,ρ]_{ij}-…
