# What is the largest linear system of equations solved using HHL experimentally?

Can someone tell what is the largest system of equations solved using HHL algorithm experimentally?

I know the $$8$$ x $$8$$ system has been solved experimentally. Has someone gone beyond this to solve $$16$$ x $$16$$ or $$32$$ x $$32$$ or beyond?

If yes please provide the resource link and also mention the number of qubits used to design the circuit.

• Could you please provide a link to a paper where 8x8 system is solved? Jun 16, 2021 at 17:35
• @MartinVesely I think it’s this one. Jun 16, 2021 at 17:44
