A Linear Algebraic Framework for Dynamic Scheduling Over Memory-Equipped Quantum Networks
Paolo Fittipaldi, Anastasios Giovanidis, Frédéric Grosshans
Quantum Internetworking is a recent field that promises numerous interesting applications, many of which require the distribution of entanglement between arbitrary pairs of users.…
Linear optical logical Bell state measurements with optimal loss-tolerance threshold
Paul Hilaire, Yaron Castor, Edwin Barnes +2
Quantum threshold theorems impose hard limits on the hardware capabilities to process quantum information. We derive tight and fundamental upper bounds to loss-tolerance thresholds…
Inflated Graph States Refuting Communication-Assisted LHV Models
Uta Isabella Meyer, Frédéric Grosshans, Damian Markham
Standard Bell inequalities hold when distant parties are not allowed to communicate. Barrett et al. found correlations from Pauli measurements on certain network graphs refute a lo…
Cost and Routing of Continuous Variable Quantum Networks
Federico Centrone, Frederic Grosshans, Valentina Parigi
We study continuous-variable graph states with regular and complex network shapes and we report for their cost as a global measure of squeezing and number of squeezed modes that ar…
Classical-quantum network coding: a story about tensor
Clément Meignant, Frédéric Grosshans, Damian Markham
We study here the conditions to perform the distribution of a pure state on a quantum network using quantum operations which can succeed with a non-zero probability, the Stochastic…
Non-Destructive Zero-Knowledge Proofs on Quantum States, and Multi-Party Generation of Authorized Hidden GHZ States
Léo Colisson, Frédéric Grosshans, Elham Kashefi
We propose the first generalization of the famous Non-Interactive Zero-Knowledge (NIZK) proofs to quantum languages (NIZKoQS) and we provide a protocol to prove advanced properties…
Witnessing Wigner Negativity
Ulysse Chabaud, Pierre-Emmanuel Emeriau, Frédéric Grosshans
Negativity of the Wigner function is arguably one of the most striking non-classical features of quantum states. Beyond its fundamental relevance, it is also a necessary resource f…
Error-correcting entanglement swapping using a practical logical photon encoding
Paul Hilaire, Edwin Barnes, Sophia E. Economou +1
Several emerging quantum technologies, including quantum networks, modular and fusion-based quantum computing, rely crucially on the ability to perform photonic Bell state measurem…
Certification of non-Gaussian states with operational measurements
Ulysse Chabaud, Ganaël Roeland, Mattia Walschaers +4
We derive a theoretical framework for the experimental certification of non-Gaussian features of quantum states using double homodyne detection. We rank experimental non-Gaussian s…
Classical simulation of Gaussian quantum circuits with non-Gaussian input states
Ulysse Chabaud, Giulia Ferrini, Frédéric Grosshans +1
We consider Gaussian quantum circuits supplemented with non-Gaussian input states and derive sufficient conditions for efficient classical strong simulation of these circuits. In p…
Breaking simple quantum position verification protocols with little entanglement
Andrea Olivo, Ulysse Chabaud, André Chailloux +1
Instantaneous nonlocal quantum computation (INQC) evades apparent quantum and relativistic constraints and allows to attack generic quantum position verification (QPV) protocols (a…
Efficient verification of Boson Sampling
Ulysse Chabaud, Frédéric Grosshans, Elham Kashefi +1
The demonstration of quantum speedup, also known as quantum computational supremacy, that is the ability of quantum computers to outperform dramatically their classical counterpart…
Detecting a target with quantum entanglement
Giacomo Sorelli, Nicolas Treps, Frederic Grosshans +1
In the last decade a lot of research activity focused on the use of quantum entanglement as a resource for remote target detection, i.e. on the design of a quantum radar. The liter…
Stellar representation of non-Gaussian quantum states
Ulysse Chabaud, Damian Markham, Frédéric Grosshans
The so-called stellar formalism allows to represent the non-Gaussian properties of single-mode quantum states by the distribution of the zeros of their Husimi Q-function in phase-s…
Building trust for continuous variable quantum states
Ulysse Chabaud, Tom Douce, Frédéric Grosshans +2
In this work we develop new methods for the characterisation of continuous variable quantum states using heterodyne measurement in both the trusted and untrusted settings. First, b…
Semi-device-independent quantum money with coherent states
Mathieu Bozzio, Eleni Diamanti, Frédéric Grosshans
The no-cloning property of quantum mechanics allows unforgeability of quantum banknotes and credit cards. Quantum credit card protocols involve a bank, a client and a payment termi…
Distributing Graph States Over Arbitrary Quantum Networks
Clément Meignant, Damian Markham, Frédéric Grosshans
Multipartite entangled states are great resources for quantum networks. In this work we study the distribution, or routing, of entangled states over fixed, but arbitrary, physical…
Random coding for sharing bosonic quantum secrets
Francesco Arzani, Giulia Ferrini, Frédéric Grosshans +1
We consider a protocol for sharing quantum states using continuous variable systems. Specifically we introduce an encoding procedure where bosonic modes in arbitrary secret states…
Investigating the optimality of ancilla-assisted linear optical Bell measurements
Andrea Olivo, Frédéric Grosshans
In the last decade Grice and Ewert and van Loock found linear optical networks achieving near-unit efficiency unambiguous Bell state discrimination, when fed with increasingly comp…
Thermalization in a 1D Rydberg gas: validity of the microcanonical ensemble hypothesis
Ruben Y. Cohen, Etienne Brion, Frédéric Grosshans
We question the microcanonical hypothesis, often made to account for the thermalization of complex closed quantum systems, on the specific example of a chain of two-level atoms opt…
Factoring Safe Semiprimes with a Single Quantum Query
Frédéric Grosshans, Thomas Lawson, François Morain +1
Shor's factoring algorithm (SFA), by its ability to efficiently factor large numbers, has the potential to undermine contemporary encryption. At its heart is a process called order…
A Tight Lower Bound for the BB84-states Quantum-Position-Verification Protocol
