Shane Mansfield
I am interested in the application of structural and logical methods from mathematics and theoretical computer science to physics. Much of my work focusses on behaviours which are available to quantum systems but provably unachievable with classical systems such as nonlocality, contextuality and ψ-ontology. I am particularly concerned with developing general approaches to treating these phenomena and understanding how to systematically exploit them to obtain advantages over classical systems in information theoretic tasks, computational power, security or otherwise.

My work has mostly been devoted to quantum information processing with systems described by infinite-dimensional Hilbert spaces, also known as continuous-variable systems. In particular, I am interested in the realisation of quantum computation and communication protocols with existing technology, especially in the quantum optics setting.

I am interested in the effects of atmospheric turbulence on quantum communication. My work is focused on the evaluation of its impact on continuous-variable quantum-key-distribution (CV-QKD), studying in particular the satellite-to-ground channel. The goal of the project is to understand if this technology is well suited for space applications, which represent a fundamental step towards the extension of quantum communication to a global level.

I am focused on the experimental implementation of continuous-variable quantum key distribution and in particular its adaptation to the continuous-wave methods of classical telecom systems in order to reach higher transmission rates. I also work on the establishement of the Ile-de-France testbed for quantum secure communications which aims to link universities with a focus on interoperability of systems. Currently at its early stages, this testbed will be used to test different QKD systems, both commercial and lab-specific in CV and DV as well as multiplexing with classical signals.

I have been working on the entanglement of spatial modes of light, with a particular focus on orbital-angular-momentum carrying modes, and their stability under deterministic as well as random perturbations, such as atmospheric turbulence. I am now part of a multidisciplinary team bringing together people from LKB, LIP6 and Onera to understand the role of entanglement in remote sensing applications both in the optical (LIDAR) and the microwave (RADAR) regimes. |

I am currently looking into improving quantum money protocols' practicality and providing the first experimental demonstration of an "on-the-fly" quantum credit card. The implementation and security proof takes into account the characteristics of quantum memories, and the next step is to investigate how this setup can be coupled to a state-of-the art quantum memory.

I am interested in the experimental realization of Quantum Communications in space. In particular, I work with Continuous Variables Quantum Key Distribution (CVQKD) and my PhD is also funded by Thales Alenia Space for the use of the cryptographic protocols using satellites. In parallel, I am also investigating the creation of novel quantum states of light with properties that can be potentially applied in a broader area of quantum information protocols as well as in quantum computing.

I am broadly interested in identifying and understanding quantum advantages over classical computation - specifically related to contextuality - arising in quantum systems. More precisely, my work focuses on a new version of contextuality introduced by Shane Mansfield which provides new frameworks for witnessing quantum advantages.

My project focuses mostly on experimental photonic implementation of Quantum Cryptography and Communication protocols. These protocols are based on single or entangled photons, such as Authenticated Quantum Teleportation, Anonymous Transmission or Weak Coin Flipping. I am also interested in related topics, such as Self-Testing of Entangled States and Measurements, Quantum State Tomography, or second order Nonlinear Optics.

I am interested in mathematical frameworks for quantum computation in atypical Hilbert spaces such as those which arise as spaces of functions over groups. I study gate models as well as MBQC protocols for (some of) these spaces and the algebraic problems that arise therein. I also have a soft spot for categorical methods in quantum mechanics and would like to see if graphical languages similar to the ZX-calculus can be defined in some of these spaces. My current work focuses on continuous variables quantum computation as a base case for these kinds of constructions.

My research interests are mostly concerned in applications of quantum mechanics from a theoretical and computational point of view, although I wish to be involved in their physical and experimental realizations.. Nonetheless, I am also interested in the foundations of the theory, the emergence of classicality and complexity from elementary quantum systems.

My research aims to address the question: 'How can one distribute quantum resources over quantum
networks?’. This topic led me to work on different domains such as the routing of classical and quantum information, state conversion protocol under LOCC (Local Operation and Classical Communication) and graph theory.
Currently, I research actively the use of quantum networks to share multipartite resources such as multipartite entangled states or multiple bipartite entangled states on different kind of networks.

I am working on various aspects concerning quantum metrology and quantum sensing. Currently, I am exploring two different areas. The first is applications of quantum sensing such as synchronized atomic clocks and gravimeters. The latter is building a bridge between quantum metrology and other (relevant) areas of quantum information.

A central application in this field is quantum key distribution (QKD), which allows two parties to share a secret key that can be subsequently used for message exchange, even in the presence of eavesdroppers with unlimited power. This is impossible by classical means. Continuous-variable (CV) QKD, where the key information is encoded on the quadratures of the electromagnetic field, is particularly appealing from a practical point of view in that it only requires off-the-shelf telecom components for their implementation as the PhD thesis supervisors have shown in fibre-optic long-distance experiments [Nature Photon. 7, 378 (2013)]. Since these results, the work on CV-QKD in our group has focused on the photonic and network integration of such systems.
In this doctoral project, we propose to address the many challenges that are found on the way to the development of advanced cost-effective telecom network integrated CV-QKD systems that are ready to operate in a deployed optical fibre environment. These include the conception and implementation of solutions for a system operation in the so-called local Local Oscillator configuration, with suitable modulation schemes (and associated security proofs), as well as with adapted high-speed electronics. The thesis work will also include the characterization of photonic integrated CV-QKD transmitter and receiver chips on both the silicon and indium phosphide platforms, and their use for secret key generation. This will be crucial for future scalable solutions for QKD systems.

My thesis is about the hardware secure enclave for quantum cryptography. The work could be devided into 3 steps generally. Firstly is to understand the possibility to remotely and securely control the various operations of a quantum communication protocol using classical hardware enclave, where these controls are with the analog and digital interfaces. Secondly is to define a Q enclave, which could execute the quantum operation based on the superposition inputs. Finally I will try to use secure hardware enclaves to improve the security or efficiency of quantum communication protocols.

I am working on developing sources for pseudorandom unitaries which provably mimic genuinely (Haar) random unitaries up to a certain precision. My goal is to generate there pseudorandom unitaries in the framework of MBQC in the simplest way possible. I also aim at studying applications of these unitaries to various fields such as cryptography, thermodynamics and black hole physics.
