Triangle Quantum Computing Seminar Series

Join Today’s Duke, NC State and UNC collaborative Triangle Quantum Computing Seminar 

Talk Title:  Variational Quantum Boltzmann Machines

Speaker: Christa Zoufal, IBM – Zurich

Hosted by:  IBM Quantum Hub at NC State

Abstract:  This work presents a novel realization approach to Quantum Boltzmann Machines (QBMs). The preparation of the required Gibbs states, as well as the evaluation of the loss function’s analytic gradient is based on Variational Quantum Imaginary Time Evolution, a technique that is typically used for ground state computation. In contrast to existing methods, this implementation facilitates near-term compatible QBM training with gradients of the actual loss function for arbitrary parameterized Hamiltonians which do not necessarily have to be fully-visible but may also include hidden units. The variational Gibbs state approximation is demonstrated with numerical simulations and experiments run on real quantum hardware provided by IBM Quantum. Furthermore, we illustrate the application of this variational QBM approach to generative and discriminative learning tasks using numerical simulation.

This is a Hybrid Event with NC State.
