Improved quantum algorithm for A-optimal projection
Shi-Jie Pan, Lin-Chun Wan, Hai-Ling Liu +4
Dimensionality reduction (DR) algorithms, which reduce the dimensionality of a given data set while preserving the information of the original data set as well as possible, play an…
Nonlocal sets of orthogonal product states in arbitrary multipartite quantum system
D. H. Jiang, G. B. Xu
Recently, much attention have been paid to the constructions of nonlocal multipartite orthogonal product states. Among the existing results, some are relatively complex in structur…
Practical quantum key distribution with non-phase-randomized coherent states
Li Liu, Yukun Wang, Emilien Lavie +4
Quantum key distribution (QKD) based on coherent states is well known for its implementation simplicity, but it suffers from loss-dependent attacks based on optimal unambiguous sta…
Quantum data compression by principal component analysis
Chao-Hua Yu, Fei Gao, Song Lin +1
Data compression can be achieved by reducing the dimensionality of high-dimensional but approximately low-rank datasets, which may in fact be described by the variation of a much s…
Graph comparison via nonlinear quantum search
M. Chiew, K. de Lacy, C. H. Yu +2
In this paper we present an efficiently scaling quantum algorithm which finds the size of the maximum common edge subgraph for a pair of arbitrary graphs and thus provides a meanin…
The Zero-error Entanglement Cost is Highly Non-Additive
Qiuling Yue, Eric Chitambar
The Schmidt number is an entanglement measure whose logarithm quantifies the zero-error entanglement cost of generating a given quantum state using local operations and classical c…
Self-testing using only marginal information
Xinhui Li, Yu Cai, Yunguang Han +2
The partial states of a multipartite quantum state may carry a lot of information: in some cases, they determine the global state uniquely. This result is known for tomographic inf…
Communicating via ignorance: Increasing communication capacity via superposition of order
K. Goswami, Y. Cao, G. A. Paz-Silva +2
Classically, no information can be transmitted through a depolarising, that is a completely noisy, channel. We show that by combining a depolarising channel with another channel in…
Quantum algorithm for visual tracking
Chao-Hua Yu, Fei Gao, Chenghuan Liu +3
Visual tracking (VT) is the process of locating a moving object of interest in a video. It is a fundamental problem in computer vision, with various applications in human-computer…
Construnctions of LOCC indistinguishable set of generalized Bell states
Jiang-Tao Yuan, Cai-Hong Wang, Ying-Hui Yang +1
In this paper, we mainly consider the local indistinguishability of the set of mutually orthogonal bipartite generalized Bell states (GBSs). We construct small sets of GBSs with ca…
An improved quantum algorithm for ridge regression
Chao-Hua Yu, Fei Gao, Qiao-Yan Wen
Ridge regression (RR) is an important machine learning technique which introduces a regularization hyperparameter to ordinary multiple linear regression for analyzing data suff…
Decomposition of split-step quantum walks for simulating Majorana modes and edge states
Wei-Wei Zhang, Sandeep K. Goyal, Christoph Simon +1
We construct a decomposition procedure for converting split-step quantum walks into ordinary quantum walks with alternating coins, and we show that this decomposition enables a fea…
Hadamard quantum broadcast channels
Qingle Wang, Siddhartha Das, Mark M. Wilde
We consider three different communication tasks for quantum broadcast channels, and we determine the capacity region of a Hadamard broadcast channel for these various tasks. We def…
Asymptotic Quantum Algorithm for the Toeplitz Systems
Lin-Chun Wan, Chao-Hua Yu, Shi-Jie Pan +3
Solving the Toeplitz systems, which is to find the vector such that given an Toeplitz matrix and a vector , has a variety of applications in mat…
Self-tallying Quantum Anonymous Voting
Qingle Wang, Chaohua Yu, Fei Gao +2
Anonymous voting is a voting method of hiding the link between a vote and a voter, the context of which ranges from governmental elections to decision making in small groups like c…
Creating cat states in one-dimensional quantum walks using delocalized initial states
Wei-Wei Zhang, Sandeep K. Goyal, Fei Gao +2
Cat states are coherent quantum superpositions of macroscopically distinct states and are useful for understanding the boundary between the classical and the quantum world. Due to…
