Rate-Fidelity Control for Wide-Area Quantum Links
Connor Clayton, Cory Nunn, Quinn Carmack +4
Quantum network links must distribute entanglement at high rates while satisfying application-specified fidelity demands. However, wide-area deployed fiber links suffer from polari…
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…
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…
Differentiable Quantum Computing for Large-scale Linear Control
Connor Clayton, Jiaqi Leng, Gengzhi Yang +3
As industrial models and designs grow increasingly complex, the demand for optimal control of large-scale dynamical systems has significantly increased. However, traditional method…
Efficient Routing on Quantum Networks using Adaptive Clustering
Connor Clayton, Xiaodi Wu, Bobby Bhattacharjee
We introduce QuARC, Quantum Adaptive Routing using Clusters, a novel clustering-based entanglement routing protocol that leverages redundant, multi-path routing through multi-parti…
QHDOPT: A Software for Nonlinear Optimization with Quantum Hamiltonian Descent
Samuel Kushnir, Jiaqi Leng, Yuxiang Peng +2
We develop an open-source, end-to-end software (named QHDOPT), which can solve nonlinear optimization problems using the quantum Hamiltonian descent (QHD) algorithm. QHDOPT offers…
A quantum central path algorithm for linear optimization
Brandon Augustino, Jiaqi Leng, Giacomo Nannicini +2
We propose a novel quantum algorithm for solving linear optimization problems by quantum-mechanical simulation of the central path. While interior point methods follow the central…
A quantum-classical performance separation in nonconvex optimization
Jiaqi Leng, Yufan Zheng, Xiaodi Wu
In this paper, we identify a family of nonconvex continuous optimization instances, each -dimensional instance with local minima, to demonstrate a quantum-classical perfor…
