Quantum Least Square #22

Closed NicoRenaud closed 2 years ago

NicoRenaud commented 2 years ago

The calibration leads mostly to non square problems where it might be difficult to apply HHL. There is an extension to HHL for least square methods that might be interesting : https://arxiv.org/pdf/1204.5242.pdf

There are iterative solutions as well for the quantum least square : https://arxiv.org/pdf/1704.04992.pdf

These methods require QRAM and are therefore not achievable atm
