Gate-based quantum simulation of Gaussian bosonic circuits on exponentially many modes
Alice Barthe, M. Cerezo, Andrew T. Sornborger +2
We introduce a framework for simulating, on an -qubit quantum computer, the action of a Gaussian Bosonic (GB) circuit on a state over modes. Specifically, we encode th…
Architectures and random properties of symplectic quantum circuits
Diego García-Martín, Paolo Braccia, M. Cerezo
Parametrized and random unitary (or orthogonal) -qubit circuits play a central role in quantum information. As such, one could naturally assume that circuits implementing symple…
Towards large-scale quantum optimization solvers with few qubits
Marco Sciorilli, Lucas Borges, Taylor L. Patti +4
We introduce a variational quantum solver for combinatorial optimizations over binary variables using only qubits, with tunable . The number of parame…
Does provable absence of barren plateaus imply classical simulability?
M. Cerezo, Martin Larocca, Diego García-Martín +9
A large amount of effort has recently been put into understanding the barren plateau phenomenon. In this perspective article, we face the increasingly loud elephant in the room and…
Showcasing a Barren Plateau Theory Beyond the Dynamical Lie Algebra
N. L. Diaz, Diego García-Martín, Sujay Kazi +2
Barren plateaus have emerged as a pivotal challenge for variational quantum computing. Our understanding of this phenomenon underwent a transformative shift with the recent introdu…
Quantum neural networks form Gaussian processes
Diego García-Martín, Martin Larocca, M. Cerezo
It is well known that artificial neural networks initialized from independent and identically distributed priors converge to Gaussian processes in the limit of a large number of ne…
Effects of noise on the overparametrization of quantum neural networks
Diego García-Martín, Martin Larocca, M. Cerezo
Overparametrization is one of the most surprising and notorious phenomena in machine learning. Recently, there have been several efforts to study if, and how, Quantum Neural Networ…
Quantum Singular Value Decomposer
Carlos Bravo-Prieto, Diego García-Martín, José I. Latorre
We present a variational quantum circuit that produces the Singular Value Decomposition of a bipartite pure state. The proposed circuit, that we name Quantum Singular Value Decompo…
