Randomized Subsystem Descent for Fermion-to-Qubit Mapping
Gengzhi Yang, Di Wu, Haizhao Yang +2
We propose a versatile and efficient algorithmic framework for optimizing fermion-to-qubit mappings by generalizing the idea of randomized block coordinate descent. Our greedy appr…
Towards End-to-End Quantum Estimation of Non-Hermitian Pseudospectra
Gengzhi Yang, Jiaqi Leng, Xiaodi Wu +1
Non-Hermitian many-body systems can be spectrally unstable, so small perturbations may induce large eigenvalue shifts. The pseudospectrum quantifies this instability and provides a…
A Scalable Open-Source QEC System with Sub-Microsecond Decoding-Feedback Latency
Junyi Liu, Yi Lee, Yilun Xu +2
Quantum error correction (QEC) is essential for realizing large-scale, fault-tolerant quantum computation, yet its practical implementation remains a major engineering challenge. I…
Resource-efficient quantum simulation of transport phenomena via Hamiltonian embedding
Joseph Li, Gengzhi Yang, Jiaqi Leng +1
Transport phenomena play a key role in a variety of application domains, and efficient simulation of these dynamics remains an outstanding challenge. While quantum computers offer…
(Sub)Exponential Quantum Speedup for Optimization
Jiaqi Leng, Kewen Wu, Xiaodi Wu +1
We demonstrate provable (sub)exponential quantum speedups in both discrete and continuous optimization, achieved through simple and natural quantum optimization algorithms, namely…
On the Computational Complexity of Schrödinger Operators
Yufan Zheng, Jiaqi Leng, Yizhou Liu +1
We study computational problems related to the Schrödinger operator in the real space under the condition that (i) the potential function is smooth and has its valu…
