Belief propagation as a partial decoder
Laura Caune, Brendan Reid, Joan Camps +1
One of the fundamental challenges in enabling fault-tolerant quantum computation is realising fast enough quantum decoders. We present a new two-stage decoder that accelerates the…
Tangling schedules eases hardware connectivity requirements for quantum error correction
Gyorgy P. Geher, Ophelia Crawford, Earl T. Campbell
Quantum computers have the potential to change the way we solve computational problems. Due to the noisy nature of qubits, the need arises to correct physical errors occurring duri…
Statistical phase estimation and error mitigation on a superconducting quantum processor
Nick S. Blunt, Laura Caune, Róbert Izsák +2
Quantum phase estimation (QPE) is a key quantum algorithm, which has been widely studied as a method to perform chemistry and solid-state calculations on future fault-tolerant quan…
Block-encoding structured matrices for data input in quantum computing
Christoph Sünderhauf, Earl Campbell, Joan Camps
The cost of data input can dominate the run-time of quantum algorithms. Here, we consider data input of arithmetically structured matrices via block encoding circuits, the input mo…
Mind the gap: Achieving a super-Grover quantum speedup by jumping to the end
Alexander M. Dalzell, Nicola Pancotti, Earl T. Campbell +1
We present a quantum algorithm that has rigorous runtime guarantees for several families of binary optimization problems, including Quadratic Unconstrained Binary Optimization (QUB…
Parallel window decoding enables scalable fault tolerant quantum computation
Luka Skoric, Dan E. Browne, Kenton M. Barnes +2
Large-scale quantum computers have the potential to hold computational capabilities beyond conventional computers for certain problems. However, the physical qubits within a quantu…
