Abstract
Techniques are describing for designing and operating a quantum oscillator. In contrast with conventional approaches to operating a quantum oscillator, the present techniques relate to an oscillator design that has less bare nonlinearity than is conventionally thought to be necessary for efficient operation. Moreover, the oscillator may be driven at a frequency that is detuned away from the frequency at which a nonlinear oscillator is typically driven. In particular, the detuned drive frequency may be substantially different from the typical drive frequency, and furthermore may be a frequency that may be expected to produce a low coherence time without also engineering the reduced nonlinearity described above. As a result, the combination of an engineered reduced nonlinearity combined with a detuned drive may result in a well behaved oscillator with a strong effective nonlinearity that exhibits significantly longer coherence times than conventional quantum oscillators.
