Quantum technologies implementation exploiting spins in the solid. – (Charles Babin / LCAR / Seminar). – 26/06/2025, 11H

Séminaire LCAR

Charles Babin, Université Bourgogne Europe

Summary :
« Solid-state color centers are an emerging platform for chip-based quantum technologies, linking atom-like optical transitions to long-lived electron and nuclear spin clusters. There exist a large diversity of point impurities with various properties that are optically addressable, enabling diverse applications, notably for quantum metrology and quantum information processing. For example, multinode entanglement distribution between nitrogen-vacancy (NV) centers in distinct diamonds have been demonstrated. Furthermore, recent research has shown that “immortal solid-state spin qubits” based on Shor’s nine-qubit error correction code are realistically within reach.

In this seminar, I will give an overview of color centers and how to exploit their properties to implement real-world quantum technologies. I will highlight multiple potential quantum architectures capable of quantum information processing. Furthermore, I will discuss the current physical limitations of those systems and how we could circumvent those in the future. »
