Quantum Capacity Approaching Codes for the Detected-Jump Channel
, 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.

Quantum circuit design for accurate simulation of qudit channels
New Journal of Physics, 2015 We construct a classical algorithm that designs quantum circuits for algorithmic quantum simulation of arbitrary qudit channels on fault-tolerant quantum computers within a pre-specified error tolerance with respect to diamond-norm distance.

Quantum and classical capacity boosted by a Lorentz transformation
, 2014 In this paper we show that the quantum channel between two inertial observers who transmit quantum information by sending realistic photonic wave packets is a well-studied channel in quantum Shannon theory -- the Pauli channel.

Quantum Biological Channel Modeling and Capacity Calculation
Life, 2012 Quantum mechanics has an important role in photosynthesis, magnetoreception, and evolution. There were many attempts in an effort to explain the structure of genetic code and transfer of information from DNA to protein by using the concepts of quantum ...

Witnessing effective entanglement over a 2km fiber channel [PDF]
, 2010 We present a fiber-based continuous-variable quantum key distribution system. In the scheme, a quantum signal of two non-orthogonal weak optical coherent states is sent through a fiber-based quantum channel. The receiver simultaneously measures conjugate

Absolutely separating quantum maps and channels
New Journal of Physics, 2017 Absolutely separable states ϱ remain separable under arbitrary unitary transformations $U\varrho {U}^{\dagger }$ . By example of a three qubit system we show that in a multipartite scenario neither full separability implies bipartite absolute ...

Factorizations of quantum channels [PDF]
Linear Algebra and its Applications, 2018 We find a connection between the existence of a factorization of a quantum channel and the existence of low-rank solutions to certain linear matrix equations. Using this, we show that if a quantum channel is factorized by a direct integral of factors, it must lie in the convex hull of quantum channels which are factorized respectively by the factors in

Energy-Constrained LOCC-Assisted Quantum Capacity of the Bosonic Dephasing Channel
Entropy, 2023 We study the LOCC-assisted quantum capacity of a bosonic dephasing channel with energy constraint on the input states. We start our analysis by focusing on the energy-constrained squashed entanglement of the channel, which is an upper bound for the ...
