Variational MBQC Hamiltonian Ground State Learning
Contract type : Internship agreement
Level of qualifications required : Graduate degree or equivalent
Fonction : Internship Research
Assignment
Variational quantum algorithms have been proposed to discover the ground state of physically motivated Hamiltonians. This is usually proposed in the circuit model using an hardware efficient Ansatz. That is the circuit is made of parametrized native gates assembled in shallow way. This is aimed to provide enough expressivity to approach the desired ground state, while at the same time be short enough to avoid adverse effects of decoherence.
More recently, the same approach has been proposed in the Measruement Based Quantum Computation (MBQC) model. Yet, most of the work is still to be developed. The main questions are:
- How to construct Ansatze?
- How to perform the optimization?
- What loss function to use?
- How differently it behaves compared to circuit VQAs?
We have developed in the past months an approach to generate valid computational graphs that can serve as Ansatz. We are looking for a suitable problem to experiment the full variational MBQC approach to
guide the development of theoretical tools.
