Quantum imaginary time evolution with Zoe Holmes
Manage episode 470018727 series 3377506
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 states
- Comparison of QITE to Variational Quantum Eigensolver (VQE) approaches
- Challenges in variational methods, including barren plateaus and expressivity concerns
- Trade-offs between circuit depth, fidelity, and practical implementation on current hardware
- Potential for scientific value from NISQ-era devices in physics and chemistry applications
- The interplay between classical and quantum methods in advancing our understanding of quantum systems
