Operator-Projected Variational Quantum Imaginary Time Evolution
Aeishah Ameera Anuar, Francois Jamet, Fabio Gironella +2
Variational Quantum Imaginary Time Evolution (VQITE) is a leading technique for ground state preparation on quantum computers. A significant computational challenge of VQITE is the…
Quantum subspace expansion approach for simulating dynamical response functions of Kitaev spin liquids
Chukwudubem Umeano, François Jamet, Lachlan P. Lindoy +2
We develop a quantum simulation-based approach for studying properties of strongly correlated magnetic materials at increasing scale. We consider a paradigmatic example of a quantu…
Modelling non-Markovian noise in driven superconducting qubits
Abhishek Agarwal, Lachlan P. Lindoy, Deep Lall +2
Non-Markovian noise can be a significant source of errors in superconducting qubits. We develop gate sequences utilising mirrored pseudoidentities that allow us to characterise and…
Combining Matrix Product States and Noisy Quantum Computers for Quantum Simulation
Baptiste Anselme Martin, Thomas Ayral, François Jamet +2
Matrix Product States (MPS) and Operators (MPO) have been proven to be a powerful tool to study quantum many-body systems but are restricted to moderately entangled states as the n…
Anderson impurity solver integrating tensor network methods with quantum computing
Francois Jamet, Lachlan P. Lindoy, Yannic Rath +6
Solving the Anderson impurity model typically involves a two-step process, where one first calculates the ground state of the Hamiltonian, and then computes its dynamical propertie…
A fault-tolerant variational quantum algorithm with limited T-depth
Hasan Sayginel, Francois Jamet, Abhishek Agarwal +2
We propose a variational quantum eigensolver (VQE) algorithm that uses a fault-tolerant gate-set, and is hence suitable for implementation on a future error-corrected quantum compu…
