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…
Low depth amplitude estimation on a trapped ion quantum computer
Tudor Giurgica-Tiron, Sonika Johri, Iordanis Kerenidis +6
Amplitude estimation is a fundamental quantum algorithmic primitive that enables quantum computers to achieve quadratic speedups for a large class of statistical estimation problem…
Generative Quantum Learning of Joint Probability Distribution Functions
Elton Yechao Zhu, Sonika Johri, Dave Bacon +9
Modeling joint probability distributions is an important task in a wide variety of fields. One popular technique for this employs a family of multivariate distributions with unifor…
