Tutorial QT04—Fundamentals of Molecular Quantum Systems

Instructor: Arzhang Ardavan, University of Oxford

The central objective for the tutorial will be to introduce graduate students and researchers from a chemistry or materials science background to some of the physics they will encounter in the symposium “Molecular Quantum Systems.”

This will include an accessible introduction to the kind of quantum spin structures encountered in molecular systems and how it is envisaged that these structures might be useful in quantum devices or technologies. There will be a reasonably detailed pedagogical description of one of the essential experimental toolkits in the field: electron spin resonance.

Equipped with these underpinnings, the tutorial will elucidate the fundamental physical ideas underlying the 11 topics below. It will seek to motivate each topic in an intuitive and qualitative way, with the aim of contextualizing the more detailed and specific presentations that attendees will encounter in the main symposium.

Topics:

• New molecular quantum bits with improved coherence times
• Few-qubit molecular quantum systems: design, synthesis, characterization, quantum gate operations
• Molecular qubit arrays, local addressing
• Investigation of decoherence mechanisms, decoherence-free subspaces
• Optimal control of molecular quantum bits
• Optically addressable molecular quantum bits
• Electrical addressing of molecular quantum bits
• Strong coupling phenomena with molecular quantum bits
• Molecular quantum bit devices
• Quantum sensing, simulation and computing with molecular quantum bits
• Color centers as atomic defects in diamond and related materials
