Differentially private quantum sensor networks
Daniel J. Spencer, Kaiyan Shi, Emil T. Khabiboulline +2
Quantum sensing is a promising technology capable of demonstrating clear advantage over comparable classical techniques for precise measurement. One application of quantum sensing…
An efficient Pauli decomposition algorithm for structured matrices
Daniel J. Spencer, Kishor Bharti, Alexey V. Gorshkov
Decomposing classical matrices into linear combinations of Pauli strings is a major bottleneck for end-to-end implementations of near-term quantum algorithms. In this work, we cons…
Quantum error correction and fault tolerance: A comprehensive tutorial
Daniel J. Spencer, Shubham P. Jain, Andrew Tanggara +4
Noise is one of the central obstacles to building useful quantum computers, and quantum error correction (QEC) provides the framework for protecting quantum information against it.…
Qudit low-density parity-check codes
Daniel J. Spencer, Andrew Tanggara, Tobias Haug +2
Qudits offer significant advantages over qubit-based architectures, including more efficient gate compilation, reduced resource requirements, improved error-correction primitives,…
