Asymptotically Optimal Depth Fermionic Permutation on 2D Grid Quantum Architecture without Ancillas
Dantong Li, Shifan Xu, Yongshan Ding
Simulating fermionic systems on qubit hardware involves many nonlocal interactions, and efficient routing of these interactions is critical to the overall cost of fermionic simulat…
Co-Designing Error Mitigation and Error Detection for Logical Qubits
Rohan S. Kumar, Takahiro Tsunoda, Sophia H. Xue +3
Near-term quantum workloads demand error management, yet the two lightest-weight techniques, Quantum Error Detection (QED) and Probabilistic Error Cancellation (PEC), have compleme…
Local Optimization of Quantum Circuits (Extended Version)
Jatin Arora, Mingkuan Xu, Sam Westrick +4
Recent advances in quantum architectures and computing have motivated the development of new optimizing compilers for quantum programs or circuits. Even though steady progress has…
Quantum-Inspired Fidelity-based Divergence
Yifeng Peng, Dantong Li, Xinyi Li +3
Kullback--Leibler (KL) divergence is a fundamental measure of the dissimilarity between two probability distributions, but it can become unstable in high-dimensional settings due t…
