Let the Quantum Creep In: Designing Quantum Neural Network Models by Gradually Swapping Out Classical Components

1 code implementation26 Sep 2024 Peiyong Wang, Casey. R. Myers, Lloyd C. L. Hollenberg, Udaya Parampalli

To provide a more fine-grained characterisation of the impact of quantum components on the performance of neural networks, we propose a framework where classical neural network layers are gradually replaced by quantum layers that have the same type of input and output while keeping the flow of information between layers unchanged, different from most current research in quantum neural network, which favours an end-to-end quantum model.

Quantum Hamiltonian Embedding of Images for Data Reuploading Classifiers

1 code implementation19 Jul 2024 Peiyong Wang, Casey R. Myers, Lloyd C. L. Hollenberg, Udaya Parampalli

Conventionally, the design of quantum machine learning algorithms relies on the ``quantisation" of classical learning algorithms, such as using quantum linear algebra to implement important subroutines of classical algorithms, if not the entire algorithm, seeking to achieve quantum advantage through possible run-time accelerations brought by quantum computing.

Towards quantum enhanced adversarial robustness in machine learning

no code implementations22 Jun 2023 Maxwell T. West, Shu-Lok Tsang, Jia S. Low, Charles D. Hill, Christopher Leckie, Lloyd C. L. Hollenberg, Sarah M. Erfani, Muhammad Usman

Machine learning algorithms are powerful tools for data driven tasks such as image classification and feature detection, however their vulnerability to adversarial examples - input samples manipulated to fool the algorithm - remains a serious challenge.

GASP -- A Genetic Algorithm for State Preparation

no code implementations22 Feb 2023 Floyd M. Creevey, Charles D. Hill, Lloyd C. L. Hollenberg

Results achieved by GASP outperform Qiskit's exact general circuit synthesis method on a variety of states such as Gaussian states and W-states, and consistently show the method reduces the number of gates required for the quantum circuits to generate these quantum states to the required accuracy.

Architectural design for a topological cluster state quantum computer

1 code implementation13 Aug 2008 Simon J. Devitt, Austin G. Fowler, Ashley M. Stephens, Andrew D. Greentree, Lloyd C. L. Hollenberg, William J. Munro, Kae Nemoto

The development of a large scale quantum computer is a highly sought after goal of fundamental research and consequently a highly non-trivial problem.
