Quantum machine learning geospatial time-series by seasonal encoding
Devjyoti Tripathy, Reece Robertson, Josey Stevens +2
Quantum data reuploading models can increase the expressive capacity of variational quantum models, but do not necessarily improve predictive performance. In the present work, we i…
Procrustes Tomography -- reconstructing noisy quantum channels made easy
Josey Stevens, Reece Robertson, Sebastian Deffner
What is the most expensive part of quantum device characterization? Clearly, the answer is quantum process tomography. However, especially for noisy intermediate-scale quantum (NIS…
Variational Gibbs State Preparation on Trapped-Ion Devices
Reece Robertson, Mirko Consiglio, Josey Stevens +3
We implement a variational quantum algorithm for Gibbs state preparation of a transverse-field Ising model on IonQ's quantum computers. To this end, we train the variational parame…
Thermodynamic significance of QUBO encoding on quantum annealers
Emery Doucet, Zakaria Mzaouali, Reece Robertson +3
Quadratic unconstrained binary optimization (QUBO) is the standard interface to quantum annealers, yet a single constrained task admits many QUBO encodings whose penalty choices re…
