Quantum Capacity Approaching Codes for the Detected-Jump Channel [PDF]
Physical Review A, vol. 82, no. 6, December 2010, 062324, 2010 The quantum channel capacity gives the ultimate limit for the rate at which quantum data can be reliably transmitted through a noisy quantum channel. Degradable quantum channels are among the few channels whose quantum capacities are known.

The Structure and Quantum Capacity of a Partially Degradable Quantum Channel [PDF]
IEEE Access, 2014 The quantum capacity of degradable quantum channels has been proven to be additive. On the other hand, there is no general rule for the behavior of quantum capacity for antidegradable quantum channels.

Asymptotic Theory of Quantum Channel Estimation
PRX Quantum, 2021 The quantum Fisher information (QFI), as a function of quantum states, measures the amount of information that a quantum state carries about an unknown parameter.

Noise effects on One-Pauli Channels [PDF]
Phys.Lett. A259 (1999) 349-354, 1999 The possibility of stochastic resonance of a quantum channel and hence the noise enhanced quantum channel capacity is explored by considering one-Pauli channels which are more classical like.

Efficient universal quantum channel simulation in IBM's cloud quantum computer [PDF]
arXiv, 2017 The study of quantum channels is the fundamental field and promises wide range of applications, because any physical process can be represented as a quantum channel transforming an initial state into a final state. Inspired by the method performing non-unitary operator by the linear combination of unitary operations, we proposed a quantum algorithm for

Fundamental limitations on distillation of quantum channel resources. [PDF]
Nat Commun, 2021 Quantum channels underlie the dynamics of quantum systems, but in many practical settings it is the channels themselves that require processing. We establish universal limitations on the processing of both quantum states and channels, expressed in the ...

Fluctuation Theorems for a Quantum Channel [PDF]
Physical Review X, 2019 We establish the general framework of quantum fluctuation theorems by finding the symmetry between the forward and backward transitions of any given quantum channel.

Amortization does not enhance the max-Rains information of a quantum channel [PDF]
New Journal of Physics, 2018 Given an entanglement measure E , the entanglement of a quantum channel is defined as the largest amount of entanglement E that can be generated from the channel, if the sender and receiver are not allowed to share a quantum state before using the ...
