This paper proposes a machine learning method to characterize photonic states via a simple optical circuit and data processing of photon number distributions, such as photonic patterns. The input states consist of two coherent states used as references and a two-mode unknown state to be studied. We successfully trained supervised learning algorithms that can predict the degree of entanglement in the two-mode state as well as perform the full tomography of one photonic mode, obtaining… Expand

Experimental quantum homodyne tomography via machine learning
TLDR
This work realizes and experimentally demonstrate a method for complete characterization of a quantum harmonic oscillator based on an artificial neural network known as the restricted Boltzmann machine and applies it to optical homodyne tomography to allow full estimation of quantum states based on a smaller amount of experimental data compared to state-of-the-art methods.

Reconstruction of a Photonic Qubit State with Reinforcement Learning
TLDR
This protocol offers a tool for reconstructing an unknown quantum state when only limited copies are provided, and can also be extended to higher dimensions, multipartite, and mixed quantum state scenarios. Expand
Supervised Quantum Learning without Measurements
TLDR
A quantum machine learning algorithm for efficiently solving a class of problems encoded in quantum controlled unitary operations that introduces feedback in the dynamics and eliminates the necessity of intermediate measurements using a quantum time-delayed equation. Expand
Photonic quantum information processing: a review.
TLDR
The goal of this manuscript is to provide the reader with a comprehensive review of the state of the art in this active field with a due balance between theoretical, experimental and technological results. Expand
Neural-network quantum state tomography
TLDR
It is demonstrated that machine learning allows one to reconstruct traditionally challenging many-body quantities—such as the entanglement entropy—from simple, experimentally accessible measurements, and can benefit existing and future generations of devices. Expand
Photonic Boson Sampling in a Tunable Circuit
TLDR
The central premise of boson sampling was tested, experimentally verifying that three-photon scattering amplitudes are given by the permanents of submatrices generated from a unitary describing a six-mode integrated optical circuit. Expand
Experimental scattershot boson sampling
TLDR
The first scattershot boson sampling experiments are reported, where six different photon-pair sources are coupled to integrated photonic circuits, providing strong evidence that the photonic quantum simulator works as expected. Expand
Quantum tomography for measuring experimentally the matrix elements of an arbitrary quantum operation.
TLDR
A general method based on quantum tomography for measuring experimentally the matrix elements of an arbitrary quantum operation, which needs only a single entangled state as input. Expand
Permanents in linear optical networks
We develop an abstract look at linear optical networks from the viewpoint of combinatorics and permanents. In particular we show that calculation of matrix elements of unitarily transformed photonicExpand
Quantum Advantage with Timestamp Membosonsampling
TLDR
This work exhibits an integrated and cost-efficient shortcut stepping into the "quantum advantage" regime in a photonic system far beyond previous scenarios, and provide a scalable and controllable platform for quantum information processing. Expand
