PRL: Photonic simulation of anyonic operators

surajgoel

We’re very excited to share that our recent work was published in Physical Review Letters while also being highlighted on the cover of the journal!

In this collaboration with groups from University of Leeds and Imperial College London, we program high fidelity non-unitary qutrit operators inside a multi-mode fiber, simulating fusion and braiding of non-Abelian D(S3) anyons. For this to work, we combine techniques developed in our previous works such as characterizing multi-mode fibers, designing non-unitary operations, as well as programming optical circuits.

Introducing Xavier Toisoul, our latest addition from Erquy, France, joining BBQ Lab for his internship.

Xavier is a Physics and Chemistry major from École Centrale de Marseille, and he will explore the universe of quantum optics and complex media with us. His interests span Web 3.0, calisthenics, and the intricate world of Forex trading. He enjoys listening to music in his downtime and relishing Breton delights like Kouign-Amann.

Let’s warmly welcome Xavier and make this journey one for the books!

Nature Physics : Qudit Gates in an Optical Fiber

Light traveling through an optical fibre

We’re very excited to share our latest work that was recently published in Nature Physics! Here we program optical circuits in a disordered medium by employing the disorder itself. We use these optical circuits to manipulate, and efficiently measure, high-dimensional entangled qudits.

A complex medium consists of millions of unitary operations within itself. Our method very carefully directs light through any combination of these operations, effectively programming a new arbitrary operation. This allows us to perform any set of quantum gates on high-dimensional states of light, including the ones necessary for entanglement certification and efficient quantum measurement.

This paper is very dense in terms of the variety of techniques involved in the theoretical formulation, experiment, simulations, data analysis, and computation, and most importantly, error analysis. This work was done along our collaborators Armin Tavakoli, Claudio Conti, and Pepijn Pinkse.
