3 years ago Thanks for the submission! We hope you have enjoyed participating in QHack :smiley:
We will be assessing the entries and contacting the winners separately. Winners will be publicly announced sometime in the next month.
We will also be freezing the GitHub repo as we sort through the submitted projects, so you will not be able to update this submission.

Project Description:
To enhance the Generative Adversarial Networks (GAN) used in the High Energy Physics (HEP) community for fast event simulation with Quantum Circuit Born Machine (QCBM), a versatile and efficient quantum generative model, to sample the prior (latent space). The quantum enhanced architecture, Quantum Circuit Associative Adversarial Network (QC-AAN), was shown previously to not only have similar performance as DCGAN but also have practical quantum advantages such as greater training stability on MNIST [1]. Instabilities of the training caused by diverging gradient and vanishing gradient are a major practical concern, especially for the HEP community*[2]. So, if a QC-AAN can make the training for GANs more robust, we would expect it to have practical value for the HEP community. We plan to build upon CaloGAN [3], a popular architecture to generate HEP detector responses and use vanilla CaloGAN as a baseline for comparison.
* To overcome the training instability, HEP community often uses Wasserstein GANs. Due to time constraints, we plan to investigate a quantum enhanced Wassertein GANs in the future.
Procedure
[x] Construct QC-AAN with QCBM and CaloGAN
[x] Run experiments on partial ECal Shower dataset [4] and compare QC-ANN against vanilla CaloGAN with the metrics in the next section
[ ] Optimize multi-basis QCBM
[ ] Run experiments on full ECal Shower dataset and compare QC-ANN against vanilla CaloGAN with the metrics in the next section
If time permits, repeat the experiments and compare it against
