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…
Efficient Quantum Gradient and Higher-order Derivative Estimation via Generalized Hadamard Test
Dantong Li, Dikshant Dulal, Mykhailo Ohorodnikov +2
In the context of Noisy Intermediate-Scale Quantum (NISQ) computing, parameterized quantum circuits (PQCs) represent a promising paradigm for tackling challenges in quantum sensing…
Transformer-QEC: Quantum Error Correction Code Decoding with Transferable Transformers
Hanrui Wang, Pengyu Liu, Kevin Shao +5
Quantum computing has the potential to solve problems that are intractable for classical systems, yet the high error rates in contemporary quantum devices often exceed tolerable li…
Measuring incompatibility and clustering quantum observables with a quantum switch
Ning Gao, Dantong Li, Anchit Mishra +3
The existence of incompatible observables is a cornerstone of quantum mechanics and a valuable resource in quantum technologies. Here we introduce a measure of incompatibility, cal…
