Today Google officially published in the journal Nature it's article claiming their 53 Qubit Quantum Computer (it was actually 54 Qubit but one Qubit didn't work) could solve a problem in 3 minutes and 20 seconds that it would take Summit, the world's largest supercomputer, 10,000 years to solve:
Quantum supremacy <https://www.nature.com/articles/s41586-019-1666-5> Very recently IBM, another company working on Quantum Computers, has disputed Google's claim: https://arxiv.org/pdf/1910.09534.pdf IBM says they have found a classical algorithm that if running on the largest classical supercomputer in the world could do what Google's Machine did in 2.55 days, and if all 54 Qubits had been working duplicated it in 5.80 days; that's still a lot longer than 3 minutes and 20 seconds but it's not 10,000 years. It should be noted that unlike Google IBM has not actually performed the calculation to prove what they say is true.
