Postdoctoral Position in Experimental Quantum Photonics and Quantum Information at Laboratoire Kastler Brossel, Paris

Applications are invited for a postdoctoral position in experimental quantum optics and quantum information at Laboratoire Kastler Brossel (LKB), in Paris (France), in the research group led by Prof. Julien Laurat . LKB is jointly run by Sorbonne Université, Ecole Normale Supérieure, Collège de France and CNRS.

The proposed research is included in the starting European Quantera project “ShoQC: Short range optical quantum connections” . The challenge is to develop optical quantum connections versatile enough to connect different physical quantum platforms and faithfully carry a broad range of quantum states including discrete and continuous-variable Gaussian or non-Gaussian states (for a summary of the project The successful applicant will play a key role in this cutting-edge and stimulating European consortium coordinated by P. van Loock.

The research at LKB will take place in the “Hybrid Photonics Lab” that aims at integrating continuous- and discrete-variable tools and concepts in optical hybrid realizations. These protocols can overcome some limitations of the approaches taken individually or provide novel capabilities. For instance, the team generated for the first time a so-called hybrid entanglement of light between particle-like and wave-like qubits to bridge the two approaches. The team has been exploring the uniqueness and benefits of such entanglement and harnessing this novel photonic resource. Recently, the remote state preparation of arbitrary cat qubits, the demonstration of EPR steering, or the realization of a hybrid swapping protocol towards heterogenous networks and analog-to-digital converters for quantum information have been obtained. The team also investigates various fundamental approaches to protect and manipulate quantum superpositions in phase space, including slowing down decoherence with squeezed Schrödinger cats. These experiments are based on multiple squeezing sources, quantum state engineering, superconducting single-photon detectors and homodyne detections.

Eligibility and conditions: Candidates must hold an internationally recognized PhD.-equivalent degree in a field related to experimental quantum physics. The dynamic and highly-motivated candidate should have a track record of experimental research in either quantum optics and quantum information. The position is open as soon as possible.

Application procedure: Inquiries and applications should be sent by email to Julien Laurat ( Applications should include a detailed CV, a brief statement of research interests and two names of potential referees. The call will remain open until the suitable candidate is identified.
