Thermally-induced qubit coherence in quantum electromechanics

Abstract Quantum coherence, the ability of a quantum system to be in superposition orthogonal states, is distinct feature mechanics, thus marking deviation from classical physics. Coherence finds its applications sensing and metrology, thermodynamics computation. A particularly interesting possibility observe coherence arising counter-intuitive way thermal energy that without implementation intricate protocols involving coherent driving sequences. In this manuscript, we investigate emerging hybrid composed two-level (qubit) harmonic oscillator (a material mechanical oscillator), inspired by recent experimental progress fabrication such systems. We show created composite solely interaction parts persists under relevant damping. Implementation scheme will demonstrate previously unobserved mechanisms generation can beneficial for technologies with oscillators qubits.
