Measurement-Driven Adaptive Low-Overhead Implementation of Multi-Controlled Toffoli Gates
Abhoy Kole, Till Schnittka, Rolf Drechsler
The Toffoli gate is a fundamental building block for quantum arithmetic and reversible logic, yet its efficient realization remains a major challenge in both near-term and fault-to…
Toward Quantum Utility in Finance: A Robust Data-Driven Algorithm for Asset Clustering
Shivam Sharma, Supreeth Mysore Venkatesh, Pushkin Kachroo
Clustering financial assets based on return correlations is a fundamental task in portfolio optimization and statistical arbitrage. However, classical clustering methods often fall…
Quantum-Assisted Correlation Clustering
Antonio Macaluso, Supreeth Mysore Venkatesh, Diego Arenas +2
This work introduces a hybrid quantum-classical method to correlation clustering, a graph-based unsupervised learning task that seeks to partition the nodes in a graph based on pai…
Multireference error mitigation for quantum computation of chemistry
Hang Zou, Erika Magnusson, Hampus Brunander +2
Quantum error mitigation (QEM) strategies are essential for improving the precision and reliability of quantum chemistry algorithms on noisy intermediate-scale quantum devices. Ref…
i-QLS: Quantum-supported Algorithm for Least Squares Optimization in Non-Linear Regression
Supreeth Mysore Venkatesh, Antonio Macaluso, Diego Arenas +2
We propose an iterative quantum-assisted least squares (i-QLS) optimization method that leverages quantum annealing to overcome the scalability and precision limitations of prior q…
A partition function framework for estimating logical error curves in stabilizer codes
Leon Wichette, Hans Hohenfeld, Elie Mounzer +1
Based on the mapping between stabilizer quantum error correcting codes and disordered statistical mechanics models, we define a ratio of partition functions that measures the succe…
