PhD opportunity : Highly Entangled Dicke States with Diamond Spin Qubits in Cavities

At the cutting edge of the Second Quantum Revolution, the scaling of entanglement schemes has become a central challenge in Quantum Sciences and Technologies (QSTs) in general and in quantum information processing and quantum metrology in particular.

The goals of this PhD project are to prepare and stabilize highly entangled Dicke states in a large ensembles of NV centers placed in microwave cavities and to explore their utilization as an entanglement source for quantum information processing tasks or for quantum metrology. This involves triggering and controlling superradiance (SR) in the microwave domain (~3 GHz) and quantifying the collective quantum properties using dispersive measurements.

The outcomes will advance our understanding of quantum coherence in solid-state systems, contribute to the development of scalable quantum technologies and provide innovative tools for exploring collective effect in Cavity QED.

Responsibilities

• Design and optimize a microwave resonator able to trigger the superradiance of NV centers.
• Develop the experimental setup and protocols to trigger and stabilize the collective superradiance in NV centers placed in microwave cavities.
• Quantify the Dicke states properties by means of both local measurements and advanced dispersive measurement techniques.
• Collaborate with theorists to model the dynamics of superradiance.
• Work with the rest of the team to investigate applications in quantum metrology and quantum information processing.
• Publish findings in high-impact journals and present work at international conferences.

Qualifications

• Educational background: A Master’s degree or engineering degree in physics is required, with some of the following specialties: Cavity quantum electrodynamics in cavity (cavity metrology).
• Technical expertise: Experience with laboratory experiment interfacing (Labview, Matlab, or Python), and with numerical simulation (Comsol or Ansys HFSS) is required.
• Soft skills: Teamwork and communication skills (oral or written) are expected.
• Motivation: A passion for quantum research and an eagerness to solve complex scientific problems in a fast-paced, collaborative environment.
