Adaptive Online Learning of Quantum States
Xinyi Chen, Elad Hazan, Tongyang Li +3
The problem of efficient quantum state learning, also called shadow tomography, aims to comprehend an unknown -dimensional quantum state through POVMs. Yet, these states are rar…
Quantum simulation of real-space dynamics
Andrew M. Childs, Jiaqi Leng, Tongyang Li +2
Quantum simulation is a prominent application of quantum computers. While there is extensive previous work on simulating finite-dimensional systems, less is known about quantum alg…
Quantum autoencoders for communication-efficient quantum cloud computing
Yan Zhu, Ge Bai, Yuexuan Wang +2
In the model of quantum cloud computing, the server executes a computation on the quantum data provided by the client. In this scenario, it is important to reduce the amount of qua…
Escape saddle points by a simple gradient-descent based algorithm
Chenyi Zhang, Tongyang Li
Escaping saddle points is a central research topic in nonconvex optimization. In this paper, we propose a simple gradient-based algorithm such that for a smooth function $f\colon\m…
Hamiltonian simulation with random inputs
Qi Zhao, You Zhou, Alexander F. Shaw +2
The algorithmic error of digital quantum simulations is usually explored in terms of the spectral norm distance between the actual and ideal evolution operators. In practice, this…
