Algebraic Speedups for Exact Inversion of Hamiltonian Evolutions
Jizhe Lai, Mingrui Jing, Erdong Huang +1
Deterministic exact inversion of an arbitrary -dimensional unitary requires {} coherent forward calls in the worst case. We ask how this cost changes for Hamiltonian evo…
Phase-Stable Hologram Updates for Large-Scale Neutral-Atom Array Reconfiguration
Erdong Huang, Jiayi Huang, Hongshun Yao +2
Assembling large-scale, defect-free Rydberg atom arrays is a key technology for neutral-atom quantum computation. Dynamic holographic optical tweezers enable the assembly and recon…
Quantum Recurrent Embedding Neural Network
Mingrui Jing, Erdong Huang, Xiao Shi +2
Quantum neural networks have emerged as promising quantum machine learning models, leveraging the properties of quantum systems and classical optimization to solve complex problems…
Protocols and Trade-Offs of Quantum State Purification
Hongshun Yao, Yu-Ao Chen, Erdong Huang +3
Quantum state purification is crucial in quantum communication and computation, aiming to recover a purified state from multiple copies of an unknown noisy state. This work introdu…
