Yesterday, we released some information regarding our Hyperion-1 state-vector quantum emulator.

It is designed to scale across GPU-accelerated nodes towards the fast exploration of the 30++ (exact) qubits regime. We tested it on NVIDIA A100 GPU architecture on the Jean Zay GENCI/CNRS machine.
Big kudos to the amazing team: O. ADJOUA, C. Feniou, E. Posenitskiy, L. Lagardère.

We conducted QSP for complex molecular systems using various methods. Our simulations indicate that the recently developed Overlap-ADAPT-VQE algorithm offers the most advantageous performance for near-term applications. Computations up to 28 qubits were performed thanks to our in-house (multi)GPU-accelerated state-vector emulator on a single NVIDIA DGX-A100 !!!

4/4 · We also show a 1st implementation of a resource-efficient Overlap-ADAPT-like approach (arXiv:2301.10196). The hybrid approach is shown to provide high fidelities. 2 approaches for the quantum estimation of overlaps are provided: SWAP-Test & the Compute-Uncompute method.
3/4 · We show a successful simulation of a 25-spin Ising model through an adaptive hybrid quantum/HPC method exhibiting a quantum complexity independent of the number of qubits & extensible to other physical model Hamiltonians. The approach is shown to provide high fidelities;
