Entanglement classification and \emph{non-k}-separability certification via Greenberger-Horne-Zeilinger-class fidelity
Marcin Płodzień, Jan Chwedeńczuk, Maciej Lewenstein +1
Many-body quantum systems can be characterised using the notions of \emph{k}-separability and entanglement depth. A quantum state is \emph{k}-separable if it can be expressed as a…
Piquasso: A Photonic Quantum Computer Simulation Software Platform
Zoltán Kolarovszki, Tomasz Rybotycki, Péter Rakyta +10
We introduce the Piquasso quantum programming framework, a full-stack open-source software platform for the simulation and programming of photonic quantum computers. Piquasso can b…
Optimal Fermionic Joint Measurements for Estimating Non-Commuting Majorana Observables
Daniel McNulty, Susane Calegari, Michał Oszmaniec
An important class of fermionic observables, relevant in tasks such as fermionic partial tomography and estimating energy levels of chemical Hamiltonians, are the binary measuremen…
A Simple and Efficient Joint Measurement Strategy for Estimating Fermionic Observables and Hamiltonians
Joanna Majsak, Daniel McNulty, Michał Oszmaniec
We propose a simple scheme to estimate fermionic observables and Hamiltonians relevant in quantum chemistry and correlated fermionic systems. Our approach is based on implementing…
Introduction to quantum entanglement in many-body systems
Anubhav Kumar Srivastava, Guillem Müller-Rigat, Maciej Lewenstein +1
The quantum mechanics formalism introduced new revolutionary concepts challenging our everyday perceptions. Arguably, quantum entanglement, which explains correlations that cannot…
Metrological robustness of high photon number optical cat states
Philipp Stammer, Tomás Fernández Martos, Maciej Lewenstein +1
In the domain of quantum metrology, cat states have demonstrated their utility despite their inherent fragility with respect to losses. Here, we introduce noise robust optical cat…
Rényi-Holevo inequality from --Rényi relative entropies
Diego G. Bussandri, Grzegorz Rajchel-Mieldzioć, Pedro W. Lamberti +1
We investigate bounds in the transmission of classical information through quantum systems. Our focus lies in the generalized Holevo theorem, which provides a single-letter Holevo-…
Enhancing quantum state tomography via resource-efficient attention-based neural networks
Adriano Macarone Palmieri, Guillem Müller-Rigat, Anubhav Kumar Srivastava +3
Resource-efficient quantum state tomography is one of the key ingredients of future quantum technologies. In this work, we propose a new tomography protocol combining standard quan…
Improved simulation of quantum circuits dominated by free fermionic operations
Oliver Reardon-Smith, Michał Oszmaniec, Kamil Korzekwa
We present a classical algorithm for simulating universal quantum circuits composed of "free" nearest-neighbour matchgates or equivalently fermionic-linear-optical (FLO) gates, and…
