Title: Chemical Approaches for Quantum Information Science

Abstract: The unique combination of atomic-scale tunability, reproducibility, and chemical specificity make paramagnetic molecules a paradigm-shifting category of materials. This capability has the potential to be transformative for developing a bespoke quantum ecosystem, as, for example, the requirements for a node within a quantum communications network are distinct and potentially orthogonal to those for a quantum sensor. Our team imbued molecular qubits with the same read-out approach as defect-based systems. To achieve this, we envisioned an inverse design problem whereby we mimicked the electronic structure with an orthogonal physical structure. Using transition metal chemistry, we designed the ground state, excited states and dynamics based on straightforward ligand field analysis. By coupling optical read-out with spatial precision, we seamlessly integrated a new class of materials with existing read-out technology. Translating this discovery towards application requires a second set of proof-of-concept demonstrations to improve coherence time and correlate structure with properties.

You will need to bring your cell phone, so you can sign in.  For Zoom, please submit a chat saying hello with your first and last name, so you can receive lunch.  Lunch will be served after the seminar only to the individuals that have attended.

At 4pm, there will be a tea in ATL 2117 for our speaker and students - this is a chance for students to ask questions directly to our speaker. Refreshments will be served.
