Loss-induced quantum nonreciprocity
arxiv(2024)
摘要
Attribute to their robustness against loss and external noise, nonreciprocal
photonic devices hold great promise for applications in quantum information
processing. Recent advancements have demonstrated that nonreciprocal optical
transmission in linear systems can be achieved through the strategic
introduction of loss. However, a crucial question remains unanswered: can loss
be harnessed as a resource for generating nonreciprocal quantum correlations?
Here, we take a counterintuitive stance by engineering loss to generate a novel
form of nonreciprocal quantum correlations, termed nonreciprocal photon
blockade. We examine a dissipative three-cavity system comprising two nonlinear
cavities and a linear cavity. The interplay of loss and nonlinearity leads to a
robust nonreciprocal single- and two-photon blockade, facilitated by
destructive quantum interference. Furthermore, we demonstrate the tunability of
this nonreciprocal photon blockade by manipulating the relative phase between
the two nonlinear cavities. Remarkably, this allows for the reversal of the
direction of nonreciprocity. Our study not only sheds new light on the concept
of loss-engineered quantum nonreciprocity but also opens up a unique pathway
for the design of quantum nonreciprocal photonic devices.
