Driving the resonator in the nonlinear regime makes detecting faster
In a recent article, Harald Havir et al. present a method for rapid and efficient detection of electrical charge in quantum systems using a nonlinear resonator that amplifies the signal without matching the sensor’s dissipation conditions. Thereby, they overcome previous limitations and make it applicable to various oscillating systems. Fast and reliable detection is essential for probing quantum
