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…
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…
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…
Fault Tolerant Quantum Error Mitigation
Alvin Gonzales, Anjala M Babu, Ji Liu +2
Typically, fault-tolerant operations and code concatenation are reserved for quantum error correction due to their resource overhead. Here, we show that fault tolerant operations h…
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…
Classical simulators as quantum error mitigators via circuit cutting
Ji Liu, Alvin Gonzales, Zain H. Saleem +1
We introduce a circuit cutting-based error mitigation framework, simulated quantum error mitigation (SQEM), in which an auxiliary error-mitigation subcircuit is simulated classical…
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…
Quantum Error Mitigation by Pauli Check Sandwiching
Alvin Gonzales, Ruslan Shaydulin, Zain Saleem +1
We describe and analyze an error mitigation technique that uses multiple pairs of parity checks to detect the presence of errors. Each pair of checks uses one ancilla qubit to dete…
Guaranteeing Completely Positive Quantum Evolution
Daniel Dilley, Alvin Gonzales, Mark Byrd
In open quantum systems, it is known that if the system and environment are in a product state, the evolution of the system is given by a linear completely positive (CP) Hermitian…
Sufficient Conditions and Constraints for Reversing General Quantum Errors
Alvin Gonzales, Daniel Dilley, Mark S. Byrd
Reversing the effects of a quantum evolution, for example as is done in error correction, is an important task for controlling quantum systems in order to produce reliable quantum…
Bounds on Instantaneous Nonlocal Quantum Computation
Alvin Gonzales, Eric Chitambar
Instantaneous nonlocal quantum computation refers to a process in which spacelike separated parties simulate a nonlocal quantum operation on their joint systems through the consump…
