Quantum imaginary time evolution with Zoe Holmes

Professor Zoe Holmes from EPFL in Lausanne, Switzerland, discusses her work on quantum imaginary time evolution and variational techniques for near-term quantum computers. With a background from Imperial College London and Oxford, Holmes explores the limits of what can be achieved with NISQ (Noisy Intermediate-Scale Quantum) devices.Key topics covered:Quantum Imaginary Time Evolution (QITE) as a cooling-inspired algorithm for finding ground statesComparison of QITE to Variational Quantum Eigensolver (VQE) approachesChallenges in variational methods, including barren plateaus and expressivity concernsTrade-offs between circuit depth, fidelity, and practical implementation on current hardwarePotential for scientific value from NISQ-era devices in physics and chemistry applicationsThe interplay between classical and quantum methods in advancing our understanding of quantum systems

Om Podcasten

Your hosts, Sebastian Hassinger and Kevin Rowney, interview brilliant research scientists, software developers, engineers and others actively exploring the possibilities of our new quantum era. We will cover topics in quantum computing, networking and sensing, focusing on hardware, algorithms and general theory. The show aims for accessibility - neither of us are physicists! - and we'll try to provide context for the terminology and glimpses at the fascinating history of this new field as it evolves in real time.
