WHY INCLUDED

Killoran builds software connecting quantum computation with modern programming, coauthoring PennyLane’s differentiable framework and Strawberry Fields’ tools for designing and simulating photonic quantum circuits.

PennyLane / XanaduarXivarXiv / Quantum

Killoran’s work makes quantum ideas accessible through executable software. Strawberry Fields provides a programming and simulation environment for continuous-variable photonic circuits, while PennyLane connects parameterized quantum circuits with automatic differentiation and classical optimization. Both are collaborative projects documented in their research papers. His current PennyLane profile identifies a focus on software for fault-tolerant computing at Xanadu. The combination of algorithms, interfaces and open tools gives researchers a practical route from a mathematical circuit to an experiment.

Work, in context
  1. 2018

    Differentiable quantum programming with PennyLane

    Killoran coauthored PennyLane, a software framework that combines quantum-circuit gradients with classical automatic differentiation. Its architecture connects quantum simulators and hardware through plugins and supports optimization of hybrid quantum-classical computations.

    Coauthor of the PennyLane framework paper; the software is a collaborative project.

    Programming photonic circuits with Strawberry Fields

    As first author, Killoran introduced Strawberry Fields with a team at Xanadu. The open-source framework combines a quantum programming language, simulators and compilation tools for continuous-variable photonic circuits. The journal paper appeared in 2019.

    First author of the Strawberry Fields paper; platform development is attributed to the Xanadu team.
