The Roles of a Quantum Channel on a Quantum State [PDF]
International Journal of Theoretical Physics, 2013 When a quantum state undergoes a quantum channel, the state will be inevitably influenced. In general, the fidelity of the state is reduced, so is the entanglement if the sub- systems go through the channel. However, the influence on the coherence of the state is quite different.

Quantum Capacities of Bosonic Channels [PDF]
Phys. Rev. Lett. 98, 130501 (2007), 2006 We investigate the capacity of bosonic quantum channels for the transmission of quantum information. Achievable rates are determined from measurable moments of the channel by showing that every channel can asymptotically simulate a Gaussian channel which is characterized by second moments of the initial channel.

Controlled remote state preparation via partially entangled quantum channel [PDF]
Quantum Information Processing, 2014 We propose two controlled remote state preparation protocols via partially entangled channels. One prepares a single-qubit state, and the other prepares a two-qubit state.

IEEE Access, 2020 Quantum information is prone to suffer from errors caused by the so-called decoherence, which describes the loss in coherence of quantum states associated to their interactions with the surrounding environment.

Quantum channels and memory effects [PDF]
Reviews of Modern Physics, 2014 Any physical process can be represented as a quantum channel mapping an initial state to a final state. Hence it can be characterized from the point of view of communication theory, i.e., in terms of its ability to transfer information. Quantum information provides a theoretical framework and the proper mathematical tools to accomplish this.

The classical capacity of quantum channels with memory [PDF]
Phys. Rev. A 79, 032320 (2009), 2009 We investigate the classical capacity of two quantum channels with memory: a periodic channel with depolarizing channel branches, and a convex combination of depolarizing channels. We prove that the capacity is additive in both cases. As a result, the channel capacity is achieved without the use of entangled input states.

Effects of quantum noises on χ state-based quantum steganography protocol
Mathematical Biosciences and Engineering, 2019 Since the good application of quantum mechanism in the field of communication, quantum secure communication has become a research hotspot. The existing quantum secure communication protocols usually assume that the quantum channel is noise-free.
