Quantum-enhanced accelerometry with a nonlinear electromechanical circuit
Quantum-enhanced accelerometry with a nonlinear electromechanical circuit
It is known that placing a mechanical oscillator in a superposition of coherent states allows, in theory, a measurement of a linear force whose sensitivity increases with the amplitude of the mechanical oscillations, a uniquely quantum effect. Further, entangled versions of these states across a network of $n$ mechanical oscillators …
