Currently building interesting things, stay tuned!
 
 
 
 
 
PhD Student
CERFACS
November 2019 – October 2022 Toulouse

PhD performed in tri-partite collaboration between CERFACS, LIRMM and Total.

Research focused on quantum algorithms and their potential applications to any field of scientific computing. Particular emphasis made on PDE and linear algebra.

 
 
 
 
 
Summer PhD intern
Los Alamos National Laboratory
June 2021 – September 2021 New-Mexico (teleworking from Toulouse, France)

Highly selective program (summer school) of 10 weeks. Conducted a research project under the supervision of Carleton Coffrin, Marc Vuffray, Andrey Lokhov, Jon Nelson and Lukasz Cincio.

The school is organised by Patrick Coles, Lukasz Cincio, Yigist Subasi, Daniel O’Malley and Jamie Lattimore.

 
 
 
 
 
Research engineer
CERFACS
October 2018 – September 2019 Toulouse

Research focused on Hamiltonian simulation.

  • Implementation of a Hamiltonian simulation procedure using product formulas.
  • Implementation of a quantum wave equation solver.
 
 
 
 
 
Intern
CERFACS
February 2018 – July 2018 Toulouse

Performed a state of the art of the existing algorithms in quantum computing.

The goal of this internship was to start looking into quantum computing to figure out if this field might be interesting for CERFACS. Particular emphasis on CFD problems and more generally on PDEs.

PDEs: I am variational, leave my ansätz alone!
Variational algorithms use parameterized circuits to encode the potential solutions. This brings a whole new world of issues on the table.

PDEs: All I want for Christmas is... my result!
Most of the quantum PDE solvers encode the solution in the quantum state amplitudes. This encoding poses a serious limitation on what data can be retrieved from the quantum computer.

PDEs: theses (time) bounds are made for solvin'
For time-dependent PDEs, another boundary condition has to be provided: the initial condition. This leads to another data input problem, that might be hard to solve.

PDEs: theses (physical) bounds are made for solvin'
The domain of definition of a PDE has bounds. A value need to be attached to each point on the boundary. This can only be done via data encoding, which might be problematic for a quantum computer.

PDEs: what a nice hypercube you have here!
Partial Differential Equations (PDEs) are solved on a specific domain, called the domain of definition. But transmitting the limits of this domain to the quantum computers might be a limiting step in solving PDEs.
