Stabilizing two-qubit entanglement with dynamically decoupled active feedback
Sacha Greenfield, Leigh Martin, Felix Motzoi +3
We propose and analyze a protocol for stabilizing a maximally entangled state of two noninteracting qubits using active state-dependent feedback from a continuous two-qubit half-pa…
Monitoring fast superconducting qubit dynamics using a neural network
G. Koolstra, N. Stevenson, S. Barzili +11
Weak measurements of a superconducting qubit produce noisy voltage signals that are weakly correlated with the qubit state. To recover individual quantum trajectories from these no…
The effects of amplification of fluctuation energy scale by quantum measurement choice on quantum chaotic systems: Semiclassical analysis
S. Greenfield, Y. Shi, J. K. Eastman +2
Measurement choices in weakly-measured open quantum systems can affect quantum trajectory chaos. We consider this scenario semi-classically and show that measurement acts as nonlin…
