Mitigating errors in logical qubits

Communications Physics
Quantum error correcting codes can enable large quantum computations provided physical error rates are sufficiently low. We combine post-selection with surface code error correction through the use of exclusive decoders, which abort on decoding instances

Probability of undetected error after decoding for a concatenated coding scheme [PDF]

A concatenated coding scheme for error control in data communications is analyzed. In this scheme, the inner code is used for both error correction and detection, however the outer code is used only for error detection.

Fault Tolerant Quantum Error Mitigation

, 2023
Typically, fault-tolerant operations and code concatenation are reserved for quantum error correction due to their resource overhead. Here, we show that fault tolerant operations have a large impact on the performance of symmetry based error mitigation ...

Permanence analysis of a concatenated coding scheme for error control [PDF]

A concatenated coding scheme for error control in data communications is analyzed. In this scheme, the inner code is used for both error correction and detection, however, the outer code is used only for error detection.

Performance of concatenated Reed-Solomon trellis-coded modulation over Rician fading channels [PDF]

A concatenated coding scheme for providing very reliable data over mobile-satellite channels at power levels similar to those used for vocoded speech is described.

Multi-party entanglement in graph states

, 2005
Graph states are multi-particle entangled states that correspond to mathematical graphs, where the vertices of the graph take the role of quantum spin systems and edges represent Ising interactions.

Protecting Information Against Computational Errors and Quantum Erasures via Concatenation [PDF]

arXiv, 2013
In this work, we introduce a new concatenation scheme which aims at protecting information against the occurrence of both computational errors and quantum erasures. According to our scheme, the internal code must be a quantum loss-correcting code that does not perform measurements, while the external code must be a quantum error-correcting code.

Analog Information Decoding of Bosonic Quantum Low-Density Parity-Check Codes [PDF]

Quantum error correction is crucial for scalable quantum information-processing applications. Traditional discrete-variable quantum codes that use multiple two-level systems to encode logical information can be hardware intensive. An alternative approach

Performance of Hybrid Concatenated Trellis Codes CPFSK with Iterative Decoding over Fading Channels [PDF]

arXiv, 2011
Concatenation is a method of building long codes out of shorter ones, it attempts to meet the problem of decoding complexity by breaking the required computation into manageable segments. Concatenated Continuous Phase Frequency Shift Keying (CPFSK) facilitates powerful error correction.
