Operational Theories in Phase Space: Toy Model for the Harmonic Oscillator. (arXiv:2101.08323v1 [quant-ph]) 上午9:07 | Martin Plávala, Matthias Kleinmann | quant-ph updates on arXiv.org We construct a toy model for the harmonic oscillator that is neither classical nor quantum. The model features a discrete energy spectrum, a ground state with sharp position and momentum, an eigenstate with non-positive Wigner function… Read more →
