Open Postdoc Positions in QI Team in LIP6

Juin 5, 2024

The Quantum Information (QI) team in LIP6, Sorbonne Université, is looking for several post doc positions of various lengths on different topics:

  • Quantum Network Protocols
  • Connecting Quantum Processors / Parallel Quantum Computing
  • Networks of Quantum Sensors
  • Continuous Variable Quantum Information
  • Experimental Optical Quantum Information
  • Quantum Complexity Theory
  • Quantum Hardware Security  
  • Quantum Machine Learning 

The QI team is an interdisciplinary research group covering computer science, theoretical physics and experimental quantum optics. We are based in LIP6, Sorbonne Université, in central Paris, and are founding members of interdisciplinary centres the Quantum Information Centre Sorbonne and the Paris Centre for Quantum Technologies. We are involved in many regional, national and international initiatives in quantum information, including several EU flagship projects. We strive to promote equality, diversity, inclusion and tolerance.

More information on the posts and on the QI team, and the work we do can be found here.

Informal enquiries can be sent to the contacts for each post below.

Applicants should send their CV, a cover letter and arrange for at least two references to be sent to qi@lip6.fr

All successful candidates will be expected to manage their own research, contribute to the working life of the team, and they will also have the opportunity to help supervise students and teach.

The positions are initially for 12 months, renewable for up to 24 months, with a flexible start date.

The deadline for the first round of applications is 30/06/2024, and the second round of application is 31/08/2024. 

 

Quantum protocols

(Contacts: Damian Markham, Eleni Diamanti, Elham Kashefi)

One theoretical post-doc in quantum information networks, in the context of the European Flagship project Quantum Internet Alliance (QIA). The QIA is a large international consortium of over 45 partners across Europe from academia and industry with the focused mission of developing the future quantum internet. This position concerns the development of protocols for applications for quantum networks, such as networks of sensors, distributed and delegated quantum computation, anonymous communication e.t.c. working with collaborators across the spectrum from those building the devices themselves, to developing the software stack, to working with industry on real world use cases. 

Connecting quantum processors

(Contacts: Damian Markham, Eleni Diamanti, Elham Kashefi)

One theoretical post-doc in quantum information networks, in the context of a national collaborative project developing quantum computation infrastructure HQI. The goal is to work closely with collaborators to explore connecting quantum processors, from two different perspectives

  • Multi-quantum processor quantum computing (compiling, resources e.t.c.)
  • Networking classical and quantum processors and their cryptographic applications. 

 

Networks of quantum sensors

(Contacts: Damian Markham, Frederic Grosshans)

One theoretical post-doc to work on developing networks of quantum sensors, in the context of a collaborative research project EQUINE, in collaborators with experimentalists in LIP6, and in Nice. Networking quantum sensors allows for new sensing capacities, as well as security not possible with individual sensors. We will explore their use, and implement proof of principle demonstrations of network advantage with experimental partners.

 

Continuous Variable Quantum Information

(Contacts: Damian Markham, Frederic Grosshans)

One theoretical post-doc to work on continuous variable quantum information. The relevant perspectives includes:

  • Characterization, certification and/or verification of continuous variable resource state and operations (Cluster states, Squeezing cost, Stellar rank, Wigner negativity, etc.)
  • Quantum computing architectures with continuous variable systems
  • Quantum error-correction with continuous variable systems
  • Quantum communication protocols with continuous variable

 

Experimental optical quantum communication and cryptography

(Contact: Eleni Diamanti)

We are opening an experimental post-doc position in the context of national and European collaborative projects. The guiding line of the experiments in our quantum photonics laboratory is the demonstration of a practical quantum advantage in terms of security and efficiency for advanced communication, cryptographic and computing tasks, in the context of realistic quantum networks. We are also interested in developing and implementing robust certification and verification methods for quantum devices and systems.

 

Quantum complexity theory

(Contacts: Alex B. Grilo)

One theoretical post-doc in quantum complexity theory. We look for candidates with experience in the field, or in adjacent areas such as quantum cryptography or classical complexity theory. 
The project perspectives include (but are not limited to):

– Hamiltonian complexity
– Quantum interactive proofs
– Interplay between complexity theory and cryptography
– Interplay between complexity theory and learning theory

 

Quantum Hardware Security 

(Contacts: Elham Kashefi)

One theoretical post-doc to work within the recently awarded Quantera at QI team on « Hardware Security Module for secure delegated Quantum Cloud Computing » joint with University of Twente, University of Edinburgh, VeriQloud, Thales Group, HU Eötvös Loránd University and  QuiX. The objective of this project is to develop a standalone trusted execution module that enables secure cloud quantum computing. This module will undergo validation within the project by demonstrating a full stack software-hardware integration of the world’s first secure optical access to a photonic quantum computing implementation for multi-user quantum cloud applications. We look for candidates with expertise in quantum cryptography to lead development of new quantum primitives that are provably secure and efficiently implementable on small and medium-scale quantum devices.

 

Quantum Machine Learning 

(Contacts: Elham Kashefi)

One theoretical post-doc in quantum machine learning, with probable experience in the field, or in adjacent areas such as quantum algorithms or classical machine learning. Our group focuses on theoretical aspects of QML: from measures of expressibility, barren plateaus and other concentration, definition of quantum advantage through classical approximability, and trade-off between these phenomena. Our goal is to find the list of conditions under which a quantum advantage in QML is still plausible. We are also interested in mitigating known caveats, through Subspace preserving QML. More generally, we are interested in anything QML, without limits, including implementation with photonic quantum computers, and more applied work.
