The Pinnacle Architecture with fixed connectivity of degree eight
Paul Webster, Tom Peham, Lawrence Z. Cohen
We show how the Pinnacle architecture can be adapted to be compatible with superconducting qubits, where the connectivity between qubits must be fixed at fabrication. Specifically,…
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…
Explicit construction of low-overhead gadgets for gates on quantum LDPC codes
Paul Webster, Samuel C. Smith, Lawrence Z. Cohen
Quantum low-density parity check (QLDPC) codes can significantly reduce the overhead of quantum computing, provided the methods for performing logical operations do not require sub…
