Breakeven demonstration of quantum low-density parity-check codes
Edwin Tham, Michael L. Goldman, Shantanu Debnath +8
High-rate quantum low-density parity-check (qLDPC) codes are a leading candidate for fault-tolerant quantum computing. They feature higher encoding rates than planar alternatives s…

Extremum seeking control of quantum gates
Erfan Abbasgholinejad, Haoqin Deng, John Gamble +4
To be useful for quantum computation, gate operations must be maintained at high fidelities over long periods of time. In addition to decoherence, slow drifts in control hardware l…
