Mode-pairing quantum key distribution (MP-QKD) is an easy-to-implement scheme that
transcends the Pirandola-Laurenza-Ottaviani-Banchi bound without using quantum …

We present a scheme of quantum repeater that uses entangled multimode coherent states
that are obtained by electro-optic modulation of symmetric and antisymmetric Schrödinger …

In this paper we consider the Liouville equation that describes the quantum nonunitary
dynamics of quantum states in optical fiber. We consider a particular case of thermalization …

Quantum key distribution with multimode subcarrier wave encoding is propitious for being
robust against environmental disturbance. For application in long-distance quantum …

Besides true quantum repeaters, a trusted node paradigm seems to be inevitable for
practical implementations (at least in the short term), and one should consider configurations …

We examine different methods to implement coherent detection in subcarrier wave quantum
key distribution (SCW QKD) systems. For classical wave fields, we present the models …

In this paper, we consider the influence of device imperfections on the performance of the
subcarrier wave quantum key distribution system. For instance, we consider the utilization of …

We report a quantum key distribution using subcarrier wave encoding in Plug&Play
configuration. Our detailed study shows how subcarrier encoding operates in a presence of …

In this paper we present the approach for description of quantum control attack based on
combined protocol and hardware loopholes. It consolidates intercept-resend attack and …

In this paper we investigate the chromatic dispersion impact on the quantum key distribution
system based on multi-mode weak coherent phase-coded states. We provide an asymptotic …
