Practicality of training a quantum-classical machine in the NISQ era
T. Dutta, Alex Jin, Clarence Liu Huihong +2 more·Jan 22, 2024
Advancements in classical computing have significantly enhanced machine learning applications, yet inherent limitations persist in terms of energy, resource and speed. Quantum machine learning algorithms offer a promising avenue to overcome these lim...
Universal scaling hypothesis of quantum spatial search in complex networks
Reiko Sato, T. Nikuni, Kayoko Nohara +2 more·Jan 22, 2024
Since quantum spatial searches on networks have a strong network dependence, the question arises whether the universal perspective exists in this quantum algorithm for various networks. Here, we propose a universal scaling hypothesis of the quantum s...
Evaluation of QCNN-LSTM for Disability Forecasting in Multiple Sclerosis Using Sequential Multisequence MRI
John D. Mayfield, I. E. Naqa·Jan 22, 2024
Introduction Quantum Convolutional Neural Network (QCNN)-Long Short-Term Memory (LSTM) models were studied to provide sequential relationships for each timepoint in MRIs of patients with Multiple Sclerosis (MS). In this pilot study, we compared three...
Quantum Architecture Search with Unsupervised Representation Learning
Yize Sun, Zixin Wu, Volker Tresp +1 more·Jan 21, 2024
Unsupervised representation learning presents new opportunities for advancing Quantum Architecture Search (QAS) on Noisy Intermediate-Scale Quantum (NISQ) devices. QAS is designed to optimize quantum circuits for Variational Quantum Algorithms (VQAs)...
Elliptic curves in continuous-variable quantum systems
Maxwell Aifer, E. Sheldon·Jan 21, 2024
Elliptic curves are planar curves which can be used to define an abelian group. The efficient computation of discrete logarithms over this group is a longstanding problem relevant to cryptography. It may be possible to efficiently compute these logar...
Counter-factual carving exponentially improves entangled-state fidelity
Joshua Ramette, Josiah Sinclair, Vladan Vuleti'c·Jan 21, 2024
We propose a new method,"counter-factual"carving, that uses the"no-jump"evolution of a probe to generate entangled many-body states of high fidelity. The probe is coupled to a target ensemble of qubits and engineered to exponentially decay at a rate ...
Majorana modes and their Floquet engineering in a trapped-ion system
Ming-Jian Gao, Yu-Peng Ma, Jun-Hong An·Jan 21, 2024
Obeying non-Abelian statistics, Majorana fermions holds a promise to implement fault-tolerant quantum computing. It was found that Majorana fermions can be simulated by the zero-energy excitation in a nanowire with strong spin-orbit coupling interact...
A comprehensive review of quantum machine learning: from NISQ to fault tolerance
Yunfei Wang, Junyu Liu·Jan 21, 2024
Quantum machine learning, which involves running machine learning algorithms on quantum devices, has garnered significant attention in both academic and business circles. In this paper, we offer a comprehensive and unbiased review of the various conc...
Quantum Inspired Chaotic Salp Swarm Optimization for Dynamic Optimization
Sanjai Pathak, Ashish Mani, Mayank Sharma +1 more·Jan 21, 2024
Many real-world problems are dynamic optimization problems that are unknown beforehand. In practice, unpredictable events such as the arrival of new jobs, due date changes, and reservation cancellations, changes in parameters or constraints make the ...
VQC-based reinforcement learning with data re-uploading: performance and trainability
Rodrigo Coelho, A. Sequeira, Luís Paulo Santos·Jan 21, 2024
Reinforcement learning (RL) consists of designing agents that make intelligent decisions without human supervision. When used alongside function approximators such as Neural Networks (NNs), RL is capable of solving extremely complex problems. Deep Q-...
Inner structure of the many-body localization transition and the fulfillment of the Harris criterion
Jie Chen, Chun Chen, Xiaoqun Wang·Jan 20, 2024
We treat the disordered Heisenberg model in 1D as the standard model of many-body localization (MBL). Two new and independent order parameters stemming solely from the half-chain von Neumann entanglement entropy $S_{\textrm{vN}}$ are introduced to pr...
Exponentially slow thermalization and the robustness of Hilbert space fragmentation
Yiqiu Han, Xiao Chen, Ethan Lake·Jan 20, 2024
The phenomenon of Hilbert space fragmentation, whereby dynamical constraints fragment Hilbert space into many disconnected sectors, provides a simple mechanism by which thermalization can be arrested. However, little is known about how thermalization...
Adaptive Quantum Optimized Centroid Initialization
Nicholas R. Allgood, Ajinkya Borle, Charles K. Nicholas·Jan 20, 2024
Prototype-based clustering algorithms such as k-means are sensitive to the selection of initial cluster centroids, with poor initialization leading to slower convergence and suboptimal solutions trapped in local minima. We present Adaptive Quantum Op...
A multiple-circuit approach to quantum resource reduction with application to the quantum lattice Boltzmann method
Melody Lee, Zhixin Song, Sriharsha Kocherla +3 more·Jan 20, 2024
This work proposes a multi-circuit quantum lattice Boltzmann method (QLBM) algorithm that leverages parallel quantum computing to reduce quantum resource requirements. Computational fluid dynamics (CFD) simulations often entail a large computational ...
