Industry-ready spin-photon interfaces for hybrid photonic quantum computing
Hêlio Huet, Hubert Lam, Thibaut Pollet +45
Hybrid photonic quantum computers, combining stationary matter qubits and flying photonic qubits, offer an intrinsically networked and resource-efficient route to large-scale, erro…
Proceedings of the Twentieth International Conference on Quantum Physics and Logic
Shane Mansfield, Benoît Valiron, Vladimir Zamdzhiev
This volume contains the proceedings of the 20th International Conference on Quantum Physics and Logic (QPL 2023). The aim of the QPL conference series is to bring together academi…
Generalised Winograd Schema and its Contextuality
Kin Ian Lo, Mehrnoosh Sadrzadeh, Shane Mansfield
Ambiguities in natural language give rise to probability distributions over interpretations. The distributions are often over multiple ambiguous words at a time; a multiplicity whi…
A general-purpose single-photon-based quantum computing platform
Nicolas Maring, Andreas Fyrillas, Mathias Pont +24
Quantum computing aims at exploiting quantum phenomena to efficiently perform computations that are unfeasible even for the most powerful classical supercomputers. Among the promis…
Solving graph problems with single-photons and linear optics
Rawad Mezher, Ana Filipa Carvalho, Shane Mansfield
An important challenge for current and near-term quantum devices is finding useful tasks that can be preformed on them. We first show how to efficiently encode a bounded $n \times…
Certified randomness in tight space
Andreas Fyrillas, Boris Bourdoncle, Alexandre Maïnos +13
Reliable randomness is a core ingredient in algorithms and applications ranging from numerical simulations to statistical sampling and cryptography. The outcomes of measurements on…
Connecting XOR and XOR* games
Lorenzo Catani, Ricardo Faleiro, Pierre-Emmanuel Emeriau +2
In this work we focus on two classes of games: XOR nonlocal games and XOR* sequential games with monopartite resources. XOR games have been widely studied in the literature of nonl…
A Model of Anaphoric Ambiguities using Sheaf Theoretic Quantum-like Contextuality and BERT
Kin Ian Lo, Mehrnoosh Sadrzadeh, Shane Mansfield
Ambiguities of natural language do not preclude us from using it and context helps in getting ideas across. They, nonetheless, pose a key challenge to the development of competent…
A Complete Equational Theory for Quantum Circuits
Alexandre Clément, Nicolas Heurtel, Shane Mansfield +2
We introduce the first complete equational theory for quantum circuits. More precisely, we introduce a set of circuit equations that we prove to be sound and complete: two circuits…
Strong Simulation of Linear Optical Processes
Nicolas Heurtel, Shane Mansfield, Jean Senellart +1
In this paper, we provide an algorithm and general framework for the simulation of photons passing through linear optical interferometers. Given photons at the input of an -…
LOv-Calculus: A Graphical Language for Linear Optical Quantum Circuits
Alexandre Clément, Nicolas Heurtel, Shane Mansfield +2
We introduce the LOv-calculus, a graphical language for reasoning about linear optical quantum circuits with so-called vacuum state auxiliary inputs. We present the axiomatics of t…
Perceval: A Software Platform for Discrete Variable Photonic Quantum Computing
Nicolas Heurtel, Andreas Fyrillas, Grégoire de Gliniasty +13
We introduce Perceval, an open-source software platform for simulating and interfacing with discrete-variable photonic quantum computers, and describe its main features and compone…
Assessing the quality of near-term photonic quantum devices
Rawad Mezher, Shane Mansfield
For near-term quantum devices, an important challenge is to develop efficient methods to certify that noise levels are low enough to allow potentially useful applications to be car…
Proceedings 17th International Conference on Quantum Physics and Logic
Benoît Valiron, Shane Mansfield, Pablo Arrighi +1
This volume contains the proceedings of the 17th International Conference on Quantum Physics and Logic (QPL 2020), which was held June 2-6, 2020. Quantum Physics and Logic is an an…
Closing Bell: Boxing black box simulations in the resource theory of contextuality
Rui Soares Barbosa, Martti Karvonen, Shane Mansfield
This chapter contains an exposition of the sheaf-theoretic framework for contextuality emphasising resource-theoretic aspects, as well as some original results on this topic. In pa…
Quantum Advantage in Information Retrieval
Pierre-Emmanuel Emeriau, Mark Howard, Shane Mansfield
Random access codes have provided many examples of quantum advantage in communication, but concern only one kind of information retrieval task. We introduce a related task - the To…
A comonadic view of simulation and quantum resources
Samson Abramsky, Rui Soares Barbosa, Martti Karvonen +1
We study simulation and quantum resources in the setting of the sheaf-theoretic approach to contextuality and non-locality. Resources are viewed behaviourally, as empirical models.…
Tsirelson's bound and Landauer's principle in a single-system game
Luciana Henaut, Lorenzo Catani, Dan E. Browne +2
We introduce a simple single-system game inspired by the Clauser-Horne-Shimony-Holt (CHSH) game. For qubit systems subjected to unitary gates and projective measurements, we prove…
Quantum Advantage from Sequential-Transformation Contextuality
Shane Mansfield, Elham Kashefi
We introduce a notion of contextuality for transformations in sequential contexts, distinct from the Bell-Kochen-Specker and Spekkens notions of contextuality. Within a transformat…
Minimum quantum resources for strong non-locality
Samson Abramsky, Rui Soares Barbosa, Giovanni Carù +3
We analyse the minimum quantum resources needed to realise strong non-locality, as exemplified e.g. by the classical GHZ construction. It was already known that no two-qubit system…
The contextual fraction as a measure of contextuality
Samson Abramsky, Rui Soares Barbosa, Shane Mansfield
We consider the contextual fraction as a quantitative measure of contextuality of empirical models, i.e. tables of probabilities of measurement outcomes in an experimental scenario…
Consequences and applications of the completeness of Hardy's nonlocality
Shane Mansfield
Logical nonlocality is completely characterized by Hardy's "paradox" in (2,2,l) and (2,k,2) scenarios. We consider a variety of consequences and applications of this fact. (i) Poly…
Possibilities Determine the Combinatorial Structure of Probability Polytopes
Samson Abramsky, Rui Soares Barbosa, Kohei Kishida +2
We study the set of no-signalling empirical models on a measurement scenario, and show that the combinatorial structure of the no-signalling polytope is completely determined by th…
Contextuality, Cohomology and Paradox
Samson Abramsky, Rui Soares Barbosa, Kohei Kishida +2
Contextuality is a key feature of quantum mechanics that provides an important non-classical resource for quantum information and computation. Abramsky and Brandenburger used sheaf…
