Abstract

Photons are essential for securely transmitting information over long distances and realizing quantum entanglement on a global scale. Recent advances in photonic quantum technologies provide the fundamental tools for generating and manipulating photons within a chip. Yet, performing large-scale experiments, involving many quantum bits (or qubits), remains a major challenge.

In this talk, I will introduce the field of integrated quantum photonics and present the current advances in building a new class of integrated devices based on mechanical motion at the nanoscale, known as nano-opto-electromechanical systems (NOEMS). Unparalleled by other methods, NOEMS enable full control over light propagation in optical circuits with low loss, which makes them fully compatible with single-photon emitters. With such an efficient strategy to control light, a fully integrated platform for quantum information processing with several qubits and logical gates, can be built.
