Quantum state preparation for multivariate functions
Matthias Rosenkranz, Eric Brunner, Gabriel Marin-Sanchez +5 more·May 31, 2024
A fundamental step of any quantum algorithm is the preparation of qubit registers in a suitable initial state. Often qubit registers represent a discretization of continuous variables and the initial state is defined by a multivariate function. We de...
QuanTA: Efficient High-Rank Fine-Tuning of LLMs with Quantum-Informed Tensor Adaptation
Zhuo Chen, Rumen Dangovski, Charlotte Loh +3 more·May 31, 2024
We propose Quantum-informed Tensor Adaptation (QuanTA), a novel, easy-to-implement, fine-tuning method with no inference overhead for large-scale pre-trained language models. By leveraging quantum-inspired methods derived from quantum circuit structu...

Dimitris Alevras, Mihir Metkar, Takahiro Yamamoto +7 more·May 30, 2024
Recent advancements in quantum computing have created new opportunities for tackling long-standing, complex combinatorial optimization problems that are intractable for classical computers. Predicting the secondary structure of mRNA is one such notor...
Efficient sparse state preparation via quantum walks
A. Gonzales, R. Herrman, Colin Campbell +4 more·May 30, 2024
Continuous-time quantum walks (CTQWs) on dynamic graphs, referred to as dynamic CTQWs, are a recently introduced universal model of computation that offers a new paradigm in which to envision quantum algorithms. In this work, we develop an algorithm ...
Hybrid Quantum Algorithm for Simulating Real-Time Thermal Correlation Functions
Elliot C. Eklund, N. Ananth·May 30, 2024
We present a hybrid Path Integral Monte Carlo (hPIMC) algorithm to calculate real-time quantum thermal correlation functions and demonstrate its application to open quantum systems. The hPIMC algorithm leverages the successes of classical PIMC as a c...
Quantum visual feature encoding revisited
Xuan-Bac Nguyen, Hoang-Quan Nguyen, Hugh Churchill +2 more·May 30, 2024
Although quantum machine learning has been introduced for a while, its applications in computer vision are still limited. This paper, therefore, revisits the quantum visual encoding strategies, the initial step in quantum machine learning. Investigat...
On Low-Rank Multiplicity-Free Fusion Categories
Gert Vercleyen·May 30, 2024
This thesis explains the methods and algorithms we used to obtain explicit F symbols, R symbols, and pivotal coefficients of all multiplicity-free pivotal fusion categories up to rank 7. The thesis starts by introducing the concept of a unitary modul...
Quantum Preference Query
Hao Liu, Xiaotian You, Raymond Chi-Wing Wong·May 30, 2024
Given a large dataset of many tuples, it is hard for users to pick out their preferred tuples. Thus, the preference query problem, which is to find the most preferred tuples from a dataset, is widely discussed in the database area. In this problem, a...
Quantum Circuit Tensors and Enumerators With Applications to Quantum Fault Tolerance
Alon Kukliansky, Brad Lackey·May 30, 2024
We extend the recently introduced notion of tensor enumerator to the circuit enumerator. We provide a mathematical framework that offers a novel method for analyzing circuits and error models without resorting to Monte Carlo techniques. We introduce ...
