Driven Boson Sampling

2017 · Physical Review Letters

Sampling the distribution of bosons that have undergone a random unitary evolution is strongly believed to be a computationally hard problem. Key to outperforming classical simulations of this task is to increase both the number …

Local Versus Global Two-Photon Interference in Quantum Networks

2020 · Physical Review Letters

We devise an approach to characterizing the intricate interplay between classical and quantum interference of two-photon states in a network, which comprises multiple time-bin modes. By controlling the phases of delocalized single photons, we manipulate …

Robustness of chaotic behavior in iterated quantum protocols

2023 · arXiv (Cornell University)

One of the simplest possible quantum circuits, consisting of a CNOT gate, a Hadamard gate and a measurement on one of the outputs is known to lead to chaotic dynamics when applied iteratively on an …

Boson sampling from non-Gaussian states

2024 · Physical Review A

Boson sampling has emerged as an important tool to demonstrate the difference between quantum and classical computers and has attracted the interest of experimentalists and theoreticians. In this work we study boson sampling from general, …
