Content

Topics for Fall 2022

"Quantum sensing and metrology" by Dr. Mayeul Chipaux

Sensing using individual or ensemble of quantum objects: photons, ions or atoms, superconducting devices, point defects in solids...
Sensitivity up to the standard quantum limit: coherence, shot noise, quantum projection noise...
Sensitivity up to the Heisenberg limit: entanglement, Fisher information, squeezing...

Specific examples based on Nitrogen-Vacancy centers in diamond will illustrate the concepts.

"Quantum Information Processing with trapped ions" by Prof. Cornelius Hempel, PSI

Basic concepts of how to use trapped ions for quantum computing
State of the art examples and the road to scale up to fault tolerant machines

"Quantum mechanics of superconducting circuits" by Prof. Vladimir Manucharyan

Circuit quantization and periodic table of superconducting artificial atoms (qubits)
Quantum computing with superconducting qubits
Extreme coupling regimes of QED and many-body simulations.

"Quantum Neural Networks" by Prof. Zoé Holmes

introduction to quantum neural networks (QNNs) and some of their potential uses
What makes a 'good' QNN? Expressibility and the barrier to trainability posed by barren plateaus

Organizers: Ch. Galland & J.-Ph. Brantut
