AI-Enabled Rapid Assembly of Thousands of Defect-Free Neutral Atom Arrays with Constant-time-overhead
Rui Lin, Han-Sen Zhong, You Li +15
Assembling increasingly larger-scale defect-free optical tweezer-trapped atom arrays is essential for quantum computation and quantum simulations based on atoms. Here, we propose a…
Efficient explicit circuit for quantum state preparation of piecewise continuous functions
Nikita Guseynov, Nana Liu
Efficiently uploading data into quantum states is essential for many quantum algorithms to achieve advantage across various applications. In this paper, we address this challenge b…
Atom Cavity Encoding for NP-Complete Problems
Meng Ye, Xiaopeng Li
We consider an atom-cavity system having long-range atomic interactions mediated by cavity modes. It has been shown that quantum simulations of spin models with this system can nat…
Efficient explicit gate construction of block-encoding for Hamiltonians needed for simulating partial differential equations
Nikita Guseynov, Xiajie Huang, Nana Liu
One of the most promising applications of quantum computers is solving partial differential equations (PDEs). By using the Schrodingerisation technique - which converts non-conserv…
Quantum algorithms for matrix geometric means
Nana Liu, Qisheng Wang, Mark M. Wilde +1
Matrix geometric means between two positive definite matrices can be defined from distinct perspectives - as solutions to certain nonlinear systems of equations, as points along ge…
Boson sampling enhanced quantum chemistry
Zhong-Xia Shang, Han-Sen Zhong, Yu-Kun Zhang +5
In this work, we give a hybrid quantum-classical algorithm for solving electronic structure problems of molecules using only linear quantum optical systems. The variational ansatz…
