High-Rate Concatenated Quantum Error-Correcting Codes for Qudits
Researchers have generalized many-hypercube (MHC) codes, a family of high-rate concatenated quantum codes, from qubits to qudits of prime dimension q. They construct level-2 and level-3 MHC codes for these higher-dimensional systems. The work is aimed at efficient fault-tolerant quantum computation using qudits.

Experimental groups could use these explicit prime-dimension qudit MHC constructions to benchmark high-rate error correction on small qudit-capable processors within two years.
Trapped-ion and superconducting platforms already manipulate qudits, and having level-2 and level-3 code parameters lowers the barrier to simulating or measuring small code instances, turning a theoretical overhead advantage into testable hardware targets.
