Detecting quantum capacities of continuous-variable quantum channels

open access: yesPhysical Review Research, 2022
Quantum communication channels and quantum memories are the fundamental building blocks of large-scale quantum communication networks. Estimating their capacity to transmit and store quantum information is crucial in order to assess the performance of ...

ON QUANTUM CAPACITY AND ITS BOUND

open access: yesInfinite Dimensional Analysis, Quantum Probability and Related Topics, 2003
The quantum capacity of a pure quantum channel and that of classical-quantum-classical channel are discussed in detail based on the fully quantum mechanical mutual entropy. It is proved that the quantum capacity generalizes the so-called Holevo bound.

Quantum Biological Channel Modeling and Capacity Calculation

open access: yesLife, 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 ...

Temporal information processing induced by quantum noise

open access: yesPhysical Review Research, 2023
Quantum computing has been moving from a theoretical phase to practical one, presenting daunting challenges in implementing physical qubits, which are subjected to noises from the surrounding environment.

Entangled inputs cannot make imperfect quantum channels perfect [PDF]

open access: yes, 2011
Entangled inputs can enhance the capacity of quantum channels, this being one of the consequences of the celebrated result showing the non-additivity of several quantities relevant for quantum information science.

Coherence requirements for quantum communication from hybrid circuit dynamics

open access: yesSciPost Physics, 2023
The coherent superposition of quantum states is an important resource for quantum information processing which distinguishes quantum dynamics and information from their classical counterparts.

Quantum capacity of an amplitude-damping channel with memory [PDF]

open access: yesQuantum Information Processing, 2012
We calculate the quantum capacity of an amplitude-damping channel with time-correlated Markov noise, for two channel uses. Our results show that memory of the channel increases its ability to transmit quantum information significantly.
