Quantum algorithms with local particle number conservation: noise effects and error correction
Michael Streif, Martin Leib, Filip Wudarski +2
Quantum circuits with local particle number conservation (LPNC) restrict the quantum computation to a subspace of the Hilbert space of the qubit register. In a noiseless or fault-t…
Character randomized benchmarking for non-multiplicity-free groups with applications to subspace, leakage, and matchgate randomized benchmarking
Jahan Claes, Eleanor Rieffel, Zhihui Wang
Randomized benchmarking (RB) is a powerful method for determining the error rate of experimental quantum gates. Traditional RB, however, is restricted to gatesets, such as the Clif…
Ferromagnetically shifting the power of pausing
Zoe Gonzalez Izquierdo, Shon Grabbe, Stuart Hadfield +3
We study the interplay between quantum annealing parameters in embedded problems, providing both deeper insights into the physics of these devices and pragmatic recommendations to…
High-Dimensional Similarity Search with Quantum-Assisted Variational Autoencoder
Nicholas Gao, Max Wilson, Thomas Vandal +3
Recent progress in quantum algorithms and hardware indicates the potential importance of quantum computing in the near future. However, finding suitable application areas remains a…
Augmented fidelities for single qubit gates
Filip Wudarski, Jeffrey Marshall, Andre Petukhov +1
An average gate fidelity is a standard performance metric to quantify deviation between an ideal unitary gate transformation and its realistic experimental implementation. The aver…
Planning for Compilation of a Quantum Algorithm for Graph Coloring
Minh Do, Zhihui Wang, Bryan O'Gorman +3
The problem of compiling general quantum algorithms for implementation on near-term quantum processors has been introduced to the AI community. Previous work demonstrated that temp…
