摘要:

Analog simulations of the three‐photon Josephson parametric amplifier indicate that the noise rise observed in experimental devices arises from occasional hopping between a mode at the pump frequency &ohgr;Pand a mode at the half‐harmonic &ohgr;P/2 . The hopping is induced by thermal noise associated with the shunt resistance.
