An efficient quantum state verification framework and its application to bosonic systems
Varun Upreti, Ulysse Chabaud
Modern quantum devices are highly susceptible to errors, making the verification of their correct operation a critical problem. Usual tomographic methods rapidly become intractable…
Complexity of quantum tomography from genuine non-Gaussian entanglement
Xiaobin Zhao, Pengcheng Liao, Francesco Anna Mele +2
Quantum state tomography, a fundamental tool for quantum physics, usually requires a number of state copies that scale exponentially with the system size, owing to the intricate qu…
Towards quantum advantage with photonic state injection
Léo Monbroussou, Eliott Z. Mamon, Hugo Thomas +3
We propose a new scheme for near-term photonic quantum device that allows to increase the expressive power of the quantum models beyond what linear optics can do. This scheme relie…
Assessing non-Gaussian quantum state conversion with the stellar rank
Oliver Hahn, Maxime Garnier, Giulia Ferrini +2
State conversion is a fundamental task in quantum information processing. Quantum resource theories allow for analyzing and bounding conversions that use restricted sets of operati…
On the role of coherence for quantum computational advantage
Hugo Thomas, Pierre-Emmanuel Emeriau, Rawad Mezher +3
Quantifying the resources available to a quantum computer appears to be necessary to separate quantum from classical computation. Among them, entanglement, nonstabilizerness and co…
Bosonic Quantum Computational Complexity
Ulysse Chabaud, Michael Joseph, Saeed Mehraban +1
Quantum computing involving physical systems with continuous degrees of freedom, such as the quantum states of light, has recently attracted significant interest. However, a well-d…
