WebOct 21, 2024 · These mechanical control protocols mostly work in precooled optomechanical systems because any quantum fluctuations due to the large thermal bath occupations can deteriorate such state preparations. Hence, it is natural to seek ways to achieve cooling in such strong optomechanical coupling regimes. WebWe present an alternative scheme to achieve Schrödinger cat states in a strong coupling hybrid cavity optomechanical system. Under the single-photon strong-coupling regime, the interaction between the atom–cavity–oscillator system can induce the mesoscopic mechanical oscillator to Schrödinger cat states. Comparing to previous schemes, the …
