“…Therefore, the steady state property is sensitively dependent on the phase difference ϕ between the two driving fields. This phase dependence mechanism is similar to those in optical molecule (dimer) system [18], superconducting artificial [19,20], chiral molecule [21][22][23][24], cavity-QED system [25,26] and cavity optomechanical system [27,28], where the coupling and driving contribute a cyclic energy-level structure.…”

We theoretically propose a photonic flash based on a linearly coupled cavity system. Via driving the two side cavities by external fields, it forms a cyclic energy-level diagram and therefore the phase difference between the driving fields acts as a controller of the steady state due to the quantum interference effect. In the optical trimer structure, we show that the perfect photonic flash can be realized in the situation of resonant driving. The perfect photonic flash scheme is furthermore generalized to multiple coupled cavity system, where the cavities with odd and even number turn bright and dark alternatively. Our proposal may be applied in the designing of quantum neon and realizing a controllable photonic localization.

“…CTQW can be made one way by taking complex-valued couplings, which is called a chiral quantum walk (CQW) [41,42,43]. Chirality emerges due to the breaking of time-reversal symmetry (TRS) [44], and it provides a significant boost to transport speed [41].…”

We investigate the chiral quantum walk (CQW) for entanglement transfer on a triangular chain. We specifically consider two and three site Bell and W type entanglement cases, respectively. Using concurrence as quantum entanglement measure, together with the Bures distance and trace distance as the measures of the fidelity of the state transfer, we evaluate the success of the entanglement transfer. We compare the entangled state transfer time and quality in CQW against continuous-time quantum random walk. Furthermore, how the chain length and back-scattering at the end of the chain influence the entanglement transfer are pointed out.
