Recovery Algorithm for Correlated Errors in Permutation-Invariant Quantum Codes
Omprakash Chandra, Yingkai Ouyang, Gopikrishnan Muraleedharan +1
Quantum Error Recovery (QER) uses knowledge of the error channel acting on a quantum system to find optimal recovery maps. The scheme restores the uncorrupted state with a fidelity…

The Pinnacle Architecture: Reducing the cost of breaking RSA-2048 to 100 000 physical qubits using quantum LDPC codes
Paul Webster, Lucas Berent, Omprakash Chandra +5
The realisation of utility-scale quantum computing inextricably depends on the design of practical, low-overhead fault-tolerant architectures. We introduce the Pinnacle Architectur…

Non-local resources for error correction in quantum LDPC codes
Omprakash Chandra, Gopikrishnan Muraleedharan, Gavin K. Brennen
Quantum low density parity check (qLDPC) codes are an attractive alternative to the surface code due to their relatively high code rate and distance. However, unlike the surface co…
