Quantum Computers Compared

Useful, see link to full article linked to below there are 24 processors!

 Scientists at the U.S. Department of Energy (DOE)'s Los Alamos National Laboratory compared leading quantum computers using the Quantum Computing User Program at DOE's Oak Ridge National Laboratory.

The researchers reviewed 24 quantum processors and ranked their performance numbers against those from vendors like IBM and Quantinuum.

They used as a metric quantum volume, which estimates the degree to which a quantum processor can perform a specific type of random complex quantum circuit.

Outcomes indicated most processors performed close to promoted quantum volume, but rarely at the top numbers vendors touted.

The researchers found higher quantum performance tended to correspond with more intensive quantum circuit compilation, in which classical programming elements are translated into quantum computer commands.
