Here, we report using a processor with programmable
superconducting qubits to create quantum states on 53 qubits, occupying a state space 253 ˘1016.
Measurements from repeated experiments sample the corresponding probability distribution, which
we verify using classical simulations.
While our processor takes about 200 seconds to sample one
instance of the quantum circuit 1 million times, a state-of-the-art supercomputer would require
approximately 10,000 years to perform the equivalent task.
This dramatic speedup relative to all
known classical algorithms provides an experimental realization of quantum supremacy on a com-
putational task and heralds the advent of a much-anticipated computing paradigm.
I'm not aware of any concrete evidence that the human brain uses quantum superpositions, so why would a quantum computer be necessary for artificial general intelligence.
