Sparsification and Dimensionality Reduction of Portfolio Optimization QUBOs with QAOA
Our project began with a simple question: if some covariances between stocks are very small, do we need to keep all of them when optimizing a portfolio? In a quantum circuit, retaining a pairwise interaction can add gates. Removing enough interactions might make the calculation easier, but it could also change which stocks are selected. We want ... read more

Quantum Agents for Diabetic Retinopathy
Diabetic retinopathy develops when diabetes damages blood vessels in the retina, producing lesions that can threaten vision. These changes are unevenly distributed: some retinal regions remain stable while others worsen. Many computational approaches summarize progression through an overall disease grade or risk score. Predicting the locations of f... read more

Optimizing Quantum State Transfer in Sparse Networks
A quantum network can be modeled as a graph, with vertices representing sites that can hold an excitation and edges representing couplings between those sites. An excitation may be spread across several sites in a superposition. As the state evolves, probability amplitudes combine through interference, changing where the excitation is likely to ... read more

A Tense Dinner: Quantizing the Prisoner's Dilemma and its Variants
Game theory is a field of applied mathematics that models interactions between independent agents, called players, in games of strategy. Game theory analyzes each player’s choices and its impact on both the overall game and every other player’s choices [1]. One of the most studied games in game theory is the Prisoner’s Dilemma [1]. In the classi... read more

Uncertainty-Aware Neural Decoding for Surface-Code Quantum Error Correction
1 Introduction:
Quantum computers must detect and correct physical errors without directly measuring the encoded quantum state. Surface codes address this problem by repeatedly measuring local stabilizers on a two-dimensional qubit lattice. Changes in those measurements, called detection events, reveal where an error may have occurred, but th... read more

On the Efficacy of Solving the Poisson Equation through a QPINN
Physics-informed neural networks (PINNs) solve differential equations by training a neural net- work while penalizing violations of the governing equation and boundary conditions in the loss function [1]. Quantum physics-informed neural networks (QPINNs) extend this idea by embedding a parameterized quantum circuit within part of the classical n... read more

QAOA Protein Groups
Protein–protein interaction (PPI) networks represent proteins as nodes and functional associations as edges, and densely connected groups within them, called communities, often correspond to shared biological function. Community detection is commonly posed as modularity maximization, which is NP-hard, so practical analyses rely on heuristics such... read more
