A matching decomposition algorithm for simulating quantum walk Hamiltonians
Mostafa Atallah, Alvin Gonzales, Daniel Dilley +3
In this work, we present a new algorithm for generating quantum circuits that efficiently implement continuous time quantum walks on arbitrary simple sparse graphs. The algorithm,…
An Interacting System and Environment with Prior Correlations Plus Local Operations Can Mimic Uncorrelated Evolution
Daniel Dilley, Alvin Gonzales, Jeffrey Larson +1
Initial system-environment correlations can induce reduced dynamics that depart from the standard completely positive (CP) description. We study when such dynamics can be reproduce…
Closed form logical error rate approximations for surface codes
Shaked Regev, Daniel Dilley, James Nutaro +2
We propose a novel method to calculate logical error rates in surface codes, assuming independent and identically distributed physical errors. These results fit well known scaling…
InterQnet: A Heterogeneous Full-Stack Approach to Co-designing Scalable Quantum Networks
Joaquin Chung, Daniel Dilley, Ely Eastman +21
Quantum communications have progressed significantly, moving from a theoretical concept to small-scale experiments to recent metropolitan-scale demonstrations. As the technology ma…
Quantum Resource Correction
Mark Byrd, Daniel Dilley, Alvin Gonzales +3
Resource theories play a crucial role in characterizing states and properties essential for quantum information processing. A significant challenge is protecting resources from err…
Efficient Entanglement Purification Circuit Design for Dual-Species Atom Arrays
Bikun Li, Daniel Dilley, Alvin Gonzales +6
Entanglement purification protocols (EPPs) are essential for generating high-fidelity entangled states in noisy quantum systems, enabling robust quantum networking and computation.…
