And where are we in the usable qubits race?

@yacc143 @jornfranke @filippo This is a tricky question because the definitions shift. A lot of these algorithms require all of the qubits to be in the same quantum circuit, but not all devices allow this and two smaller quantum computers do not combine to make a single large one in the way classical ALUs can. A lot of the recent publications have been focused around using multiple physical qubits to handle the various error conditions and present as a single logical qubit, so a system with a thousand qubits may only be one qubit from the perspective of a quantum computing algorithm that’s modelled on a perfect quantum computer.
