Generalized Perfect Codes for Symmetric Classical-Quantum Channels
IEEE Transactions on Information Theory, 2022 We define a new family of codes for symmetric classical-quantum channels and establish their optimality. To this end, we extend the classical notion of generalized perfect and quasi-perfect codes to channels defined over some finite dimensional complex Hilbert output space.

Zero-Error Coding via Classical and Quantum Channels in Sensor Networks
Sensors, 2019 Today’s sensor networks need robustness, security and efficiency with a high level of assurance. Error correction is an effective communicational technique that plays a critical role in maintaining robustness in informational transmission.

Computing Sum of Sources over a Classical-Quantum MAC [PDF]
International Symposium on Information Theory, 2021 We consider the problem of communicating a general bivariate function of two classical sources observed at the encoders of a classical-quantum multiple access channel.

Correlations in Entanglement-Assisted Prepare-and-Measure Scenarios
PRX Quantum, 2021 We investigate the correlations that can arise between Alice and Bob in prepare-and-measure communication scenarios where the source (Alice) and the measurement device (Bob) can share prior entanglement. The paradigmatic example of such a scenario is the

Dynamical Generation of Noiseless Quantum Subsystems [PDF]
, 2000 We present control schemes for open quantum systems that combine decoupling and universal control methods with coding procedures. By exploiting a general algebraic approach, we show how appropriate encodings of quantum states result in obtaining ...

An explicit construction of quantum codes from one-generator generalized quasi-cyclic codes [PDF]
MATEC Web of Conferences, 2021 In this paper, we take advantage of a class of one-generator generalized quasi-cyclic (GQC) codes of index 2 to construct quantum error-correcting codes. By studying the form of Hermitian dual codes and their algebraic structure, we propose a sufficient condition for self-orthogonality of GQC codes with Hermitian inner product.

Some New Classes of Entanglement-Assisted Quantum MDS Codes Derived From Constacyclic Codes
IEEE Access, 2019 Although quantum maximal-distance-separable (MDS) codes that satisfy the quantum singleton bound have become an important research topic in the quantum coding theory, it is not an easy task to search for quantum MDS codes with the minimum distance that ...

Entanglement-assisted communication of classical and quantum information [PDF]
, 2010 We consider the problem of transmitting classical and quantum information reliably over an entanglement-assisted quantum channel. Our main result is a capacity theorem that gives a three-dimensional achievable rate region.

Synchronization in Quantum Key Distribution Systems
Cryptography, 2017 In the description of quantum key distribution systems, much attention is paid to the operation of quantum cryptography protocols. The main problem is the insufficient study of the synchronization process of quantum key distribution systems.
