LAMP-SEMINAR

Quantum technologies are rapidly transitioning from conceptual frameworks to deployable platforms capable of advancing computation, communication, sensing, and simulation. Solid state spin defects, particularly the nitrogen vacancy (NV) center in diamond, offer a uniquely versatile architecture for this transition, combining long coherence times, optical addressability, and compatibility with chip scale integration.

In this talk, I will outline a coherent research program aimed at developing emergent quantum technologies using NV centers and related solid state defects across room temperature and cryogenic regimes. This includes nanoscale thermal and magnetic sensing, multi spin quantum registers for quantum information processing, and pathways toward spin–photon interfaces and scalable quantum networks.

To motivate and contextualize this program, I will first discuss my earlier experimental work in spin dynamics and quantum thermodynamics using large scale liquid and solid-state NMR spin registers. These systems enabled controlled studies of heat flow, quantum correlations as thermodynamic resources, fluctuation relations, thermodynamic uncertainty relations, and the emergence of time crystalline behaviour in driven many body systems. The techniques developed there, precise coherent control, noise resilient protocols, and the use of correlated quantum states to probe nonequilibrium dynamics, directly inform the challenges and opportunities in solid state quantum platforms.

Bringing these threads together, I will present a roadmap for harnessing NV centers and some other emerging defects in diamond and 2D materials for quantum information processing, quantum simulations, and nanoscale sensing. The talk will highlight how concepts from NMR, quantum thermodynamics and many body physics naturally integrate with the engineering of next generation solid state quantum devices, enabling a unified approach to both fundamental studies and scalable quantum technologies
