Generating two-mechanical mode entangled cat states, and steady-state entanglement, in cavity optomechanics in the presence of dissipation
Sanket Das, Jason Twamley
We investigate a dissipation-engineering approach to produce a phase-dependent collective-mode Schrödinger cat state involving two modes. Our model features a single cavity mode th…

Squeezing enhanced homodyne weak force sensing in cavity optomechanics
Madan Mohan Mahana, Sanket Das, Tarak Nath Dey
Cavity optomechanical systems have emerged as a promising platform for quantum sensing. Quantum mechanics imposes a standard quantum limit (SQL) on the force-sensitivity for the st…

Unconventional photon blockade in cavity QED with parametric amplification
Madan Mohan Mahana, Sanket Das, Tarak Nath Dey
We theoretically investigate the quantum-interference-induced photon blockade effect in a single two-level atom-cavity quantum electrodynamics (QED) system with degenerate parametr…
