Layered Decoding of Quantum LDPC Codes
Julien Du Crest, Francisco Garcia-Herrero, Mehdi Mhalla +2
We address the problem of performing message-passing-based decoding of quantum LDPC codes under hardware latency limitations. We propose a novel way to do layered decoding that sui…
Fault-Tolerant Preparation of Quantum Polar Codes Encoding One Logical Qubit
Ashutosh Goswami, Mehdi Mhalla, Valentin Savin
This paper explores a new approach to fault-tolerant quantum computing (FTQC), relying on quantum polar codes. We consider quantum polar codes of Calderbank-Shor-Steane type, encod…
Decoding Short LDPC Codes via BP-RNN Diversity and Reliability-Based Post-Processing
Joachim Rosseel, Valérian Mannoni, Inbar Fijalkow +1
This paper investigates decoder diversity architectures for short low-density parity-check (LDPC) codes, based on recurrent neural network (RNN) models of the belief-propagation (B…
Gradient Descent Bit-Flipping Decoding with Momentum
Valentin Savin
In this paper, we propose a Gradient Descent Bit-Flipping (GDBF) decoding with momentum, which considers past updates to provide inertia to the decoding process. We show that GDBF…
Stabilizer Inactivation for Message-Passing Decoding of Quantum LDPC Codes
Julien du Crest, Mehdi Mhalla, Valentin Savin
We propose a post-processing method for message-passing (MP) decoding of CSS quantum LDPC codes, called stabilizer-inactivation (SI). It relies on inactivating a set of qubits, sup…
Non-Binary Polar Codes for Spread-Spectrum Modulations
Valentin Savin
This paper proposes a new coded modulation scheme for reliable transmission of short data packets at very low signal-to-noise ratio, combining cyclic code shift keying modulation a…
