Benchmarking quantum co-processors in an application-centric, hardware-agnostic and scalable way
Simon Martiel, Thomas Ayral, Cyril Allouche
Existing protocols for benchmarking current quantum co-processors fail to meet the usual standards for assessing the performance of High-Performance-Computing platforms. After a sy…
Quantum Divide and Compute: Hardware Demonstrations and Noisy Simulations
Thomas Ayral, François-Marie Le Régent, Zain Saleem +2
Noisy, intermediate-scale quantum computers come with intrinsic limitations in terms of the number of qubits (circuit "width") and decoherence time (circuit "depth") they can have.…
Rotationally invariant slave-boson and density matrix embedding theory: A unified framework and a comparative study on the 1D and 2D Hubbard Model
Tsung-Han Lee, Thomas Ayral, Yong-Xin Yao +2
We present detailed benchmark ground-state calculations of the one- and two-dimensional Hubbard model utilizing the cluster extensions of the rotationally invariant slave-boson (RI…
Dynamical Mean Field Theory, Density-Matrix Embedding Theory and Rotationally Invariant Slave Bosons: a Unified Perspective
Thomas Ayral, Tsung-Han Lee, Gabriel Kotliar
We present a unified perspective on Dynamical Mean Field Theory (DMFT), Density-Matrix Embedding Theory (DMET) and Rotationally Invariant Slave Bosons (RISB). We show that DMET can…
Non-local Coulomb interactions on the triangular lattice in the high-doping regime: Spectra and charge dynamics from Extended Dynamical Mean Field Theory
Sophie Chauvin, Thomas Ayral, Lucia Reining +1
We explore the two-dimensional extended Hubbard model on the triangular lattice in the high doping regime. On-site and nearest-neighbour repulsive interactions are treated in a non…
The Fierz convergence criterion: a controlled approach to strongly-interacting systems with small embedded clusters
Thomas Ayral, Jaksa Vucicevic, Olivier Parcollet
We present an embedded-cluster method, based on the TRILEX formalism. It turns the Fierz ambiguity, inherent to approaches based on a bosonic decoupling of local fermionic interact…
