Senior AMO Physicist, Quantum Network Demonstrator at Nu Quantum, Cambridge (UK)
Job Description
Nu Quantum is hiring a Senior AMO Physicist to help build its quantum-network demonstrator. You will work where atomic physics, cavity QED and quantum engineering meet, integrating Nu Quantum’s qubit–photon interface and cavity micro-technology with ion-trapping devices and pushing towards state-of-the-art networking rates and fidelities. It is a hands-on, cross-functional role where you shape experimental design and mentor other physicists.
