“…Indeed, mdiQKD tolerates a high optical loss of more than 40 dB and it can give a secret key rate similar to that of standard entanglementbased QKD protocols [29]. Moreover, its feasibility has already been proven both in laboratories and via fieldtests [30][31][32][33][34][35]. This suggests the viability of mdiQKD to connect theory and practice in QKD.…”

Side-channel attacks currently constitute the main challenge for quantum key distribution (QKD) to bridge theory with practice. So far two main approaches have been introduced to address this problem, (full) device-independent QKD and measurement-device-independent QKD. Here we present a third solution that might exceed the performance and practicality of the previous two in circumventing detector side-channel attacks, which arguably is the most hazardous part of QKD implementations. Our proposal has, however, one main requirement: the legitimate users of the system need to ensure that their labs do not leak any unwanted information to the outside. The security in the low-loss regime is guaranteed, while in the high-loss regime we already prove its robustness against some eavesdropping strategies.

“…However, in order to construct high-security andperformance networks, measurement-device-independent (MDI) QKD would be a very promising alternative since it not only removes all detector side-channel attacks, the most important security loophole of QKD implementations, by leaving the detection procedure to the untrusted relay but also supplies excellent performance with current technology [4][5][6][7][8][9][10].…”

Measurement-device-independent quantum key distribution (MDI-QKD), leaving the detection procedure to the third partner and thus being immune to all detector side-channel attacks, is very promising for the construction of high-security quantum information networks. We propose a scheme to implement MDI-QKD, but with continuous variables instead of discrete ones, i.e., with the source of Gaussian-modulated coherent states, based on the principle of continuous-variable entanglement swapping. This protocol not only can be implemented with current telecom components but also has high key rates compared to its discrete counterpart; thus it will be highly compatible with quantum networks.

“…The second-order sideband generation is that if the strong control field with frequency ω 1 and the weak probe field with frequency ω p are incident upon the optomechanical system, then there are output fields with frequencies ω 1 ± 2 generation, where the frequency component ω 1 + 2 is the second-order upper sideband while ω 1 − 2 is the second-order lower sideband. The signals at the second-order sideband are of great importance in understanding the nonlinear optomechanical interactions, for example, the nonlinear quantum nature of the optomechanical interactions as well as the effect of photon blockade may be revealed even in the weak-coupling regime through the signal of optomechanically induced transparency at the second sideband [9][10][11][12]. Here we focus on the process of second-order sideband generation in the presence of a coherent mechanical driving force, and show that second-order sideband generation can be tuned by adjusting the phase and amplitude of the mechanical pump.…”

Second-order sideband generation in a coherent-mechanical pumped optomechanical system is discussed, and the features of the coherent mechanical pump induced enhancement of second-order sideband generation are identified. We show that the coherent mechanical pump induced enhancement of second-order sideband generation exhibits an essential difference between the case of a weak control field and a strong control field. In the weak control field case, the efficiency of second-order sideband generation increases as the amplitude of the mechanical pump increases. In the strong control field case, the effect of optomechanically induced transparency occurs and increasing the amplitude of the mechanical pump does not always bring an enhancement of second-order sideband generation. The phase-dependent effect of the second-order sideband generation with a coherent mechanical pump is also discussed, and it is shown that the phase difference φ plays an important role in the process of second-order sideband generation.
