• Abstract: Conventional wisdom holds that quantum effects are fragile and can be destroyed by loss. Here, contrary to general belief, we show how to realize quantum revival of optical correlations at the single-photon level with the help of loss. We find that, accompanying loss-induced transparency of light in a nonlinear optical-molecule system, quantum suppression and revival of photonic correlations can be achieved. Specifically, below critical values, adding loss into the system leads to suppressions of both optical intensity and its non-classical correlations; however, by further increasing the loss beyond the critical values, quantum revival of photon blockade (PB) can emerge, resulting in loss-induced switch between single-PB and two-PB or super-Poissonian light. Our work provides a strategy to reverse the effect of loss in fully quantum regime, opening up a counterintuitive route to explore and utilize loss-tuned single-photon devices for quantum technology.

  Quantum non-Gaussian states of light have fundamental properties that are essential for a multitude of applications in quantum technology. Many features are difficult to detect using standard criteria due to optical losses and detector inefficiency. We employ a loss-mitigated verification technique utilising quantum non-Gaussian witnesses, which incorporate the known optical losses and detector inefficiency into their derivation.

  We take a counterintuitive stance by engineering loss to generate a novel form of nonreciprocal quantum correlations. The interplay of loss and nonlinearity leads to a robust nonreciprocal single- and two-photon blockade, facilitated by destructive quantum interference. Our study sheds new light on the concept of loss-engineered quantum nonreciprocity and opens up a unique pathway for the design of quantum nonreciprocal photonic devices.

  Cat states with their unique phase-space interference properties are ideal candidates for understanding quantum mechanics. They are highly susceptible to photon loss, which inevitably diminishes their quantum non-Gaussian features. Here, we protect these non-Gaussian features by compressing the phase-space distribution of a cat state.
