Time-optimal multi-qubit gates: Complexity, efficient heuristic and gate-time bounds [PDF]
Quantum 8, 1279 (2024), 2023 Multi-qubit entangling interactions arise naturally in several quantum computing platforms and promise advantages over traditional two-qubit gates. In particular, a fixed multi-qubit Ising-type interaction together with single-qubit X-gates can be used to synthesize global ZZ-gates (GZZ gates).

Gate-free state preparation for fast variational quantum eigensolver simulations
npj Quantum Information, 2021 The variational quantum eigensolver is currently the flagship algorithm for solving electronic structure problems on near-term quantum computers. The algorithm involves implementing a sequence of parameterized gates on quantum hardware to generate a ...

Pauli Error Propagation-Based Gate Rescheduling for Quantum Circuit Error Mitigation
IEEE Transactions on Quantum Engineering, 2022 Noisy intermediate-scale quantum algorithms, which run on noisy quantum computers, should be carefully designed to boost the output state fidelity. While several compilation approaches have been proposed to minimize circuit errors, they often omit the ...

Fast three-qubit Toffoli quantum gate based on three-body Förster resonances in Rydberg atoms [PDF]
Physical Review A, 2018 We propose a scheme of fast three-qubit Toffoli quantum gate for ultracold neutral-atom qubits. The scheme is based on the Stark-tuned three-body F\"{o}rster resonances, which we have observed in our recent experiment [D.B.Tretyakov et al., Phys.Rev.Lett.

Optimal Multi-Bit Toffoli Gate Synthesis
IEEE Access, 2023 Multi-bit Toffoli gates form an essential quantum gate class for quantum algorithms. They should be efficiently decomposed into elementary single- or multi-qubit quantum gates, such as CNOT, T, and Hadarmard, for a scalable implementation of a quantum ...
