Error Suppression in Distributed Quantum Computing with Heterogeneous-Distance Lattice Surgery
Daniel Dilley, Anastashia Jebraeilli, Rayat Roy +3
Distributed quantum computing requires fault-tolerant operations across inter-QPU links that can be substantially noisier than local gates. Uniformly increasing code distance provi…
A Syndrome-Extraction Framework for Distributed Lattice Surgery on Arbitrary Rotated Surface-Code Layouts
Pritesh Thakur, Daniel Dilley, Zain Saleem
Modular quantum computing is a leading candidate for scalable fault tolerant quantum computation. Performing lattice surgery using surface code patches in different modules require…
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…

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,…
Gate Teleportation vs Circuit Cutting in Distributed Quantum Computing
Shobhit Gupta, Nikolay Sheshko, Daniel J. Dilley +3
Distributing circuits across quantum processor modules will enable the execution of circuits larger than the qubit count limitations of monolithic processors. While distributed qua…
QuantEM: The quantum error management compiler
Ji Liu, Quinn Langfitt, Mingyoung Jessica Jeng +7
As quantum computing advances toward fault-tolerant architectures, quantum error detection (QED) has emerged as a practical and scalable intermediate strategy in the transition fro…
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…
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…
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.…
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…
Exploring Non-Multiplicativity in the Geometric Measure of Entanglement
Daniel Dilley, Jerry Chang, Jeffrey Larson +1
The geometric measure of entanglement (GME) quantifies how close a multi-partite quantum state is to the set of separable states under the Hilbert-Schmidt inner product. The GME ca…
Detecting Errors in a Quantum Network with Pauli Checks
Alvin Gonzales, Daniel Dilley, Bikun Li +2
We apply the quantum error detection scheme Pauli check sandwiching (PCS) to quantum networks by turning it into a distributed multiparty protocol. PCS provides protection on the t…
Some Entanglement Survives Most Measurements
Alvin Gonzales, Daniel Dilley, Mark Byrd
To prepare quantum states and extract information, it is often assumed that one can perform a perfectly projective measurement. Such measurements can achieve an uncorrelated system…
Identifying Quantum Correlations Using Explicit SO(3) to SU(2) Maps
Daniel Dilley, Alvin Gonzales, Mark Byrd
Quantum state manipulation of two-qubits on the local systems by special unitaries induces special orthogonal rotations on the Bloch spheres. An exact formula is given for determin…
