Quantum computation mediated by ancillary qudits and spin coherent states

2015 · Physical Review A

Models of universal quantum computation in which the required interactions between register (computational) qubits are mediated by some ancillary system are highly relevant to experimental realizations of a quantum computer. We introduce such a universal …

Establishing trust in quantum computations

2022 · arXiv (Cornell University)

Quantum computing hardware has grown sufficiently complex that it often can no longer be simulated by classical computers, but its computational power remains limited by errors. These errors corrupt the results of quantum algorithms, and …

Learning a Quantum Computer's Capability

2024 · IEEE Transactions on Quantum Engineering

Accurately predicting a quantum computer's capability—which circuits it can run and how well it can run them—is a foundational goal of quantum characterization and benchmarking. As modern quantum computers become increasingly hard to simulate, we …
