I also found a partial abstract : "The tantalizing promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space.

Original plan was to have 72 qubits (as noted in the FT article) but was downsized to 53 for some reason. Original reporting on the 72-qubit plan here .

"Document ID: 20190030475 Quantum Supremacy Using a Programmable Superconducting Processor The tantalizing promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here, we report using a processor with programmable superconducting qubits to create quantum states on 53 qubits, occupying a state space 2(exp53) ~ 10(exp16). 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 computational task and heralds the advent of a much-anticipated computing paradigm. 20190801 August 2019 Copyright, Public use permitted Unclassified, Unlimited, Publicly available http://hdl.handle.net/2060/20190030475 CASI application/pdf Mandra, Salvatore Rieffel, Eleanor G.

"A paper by Google’s researchers seen by the FT, that was briefly posted earlier this week on a Nasa website before being removed, claimed that their processor was able to perform a calculation in three minutes and 20 seconds that would take today’s most advanced classical computer, known as Summit, approximately 10,000 years."
Why was that paper removed on the Nasa website? Also, I'm curious if supplementary data was provided to support the claims?
The patent-pending Joshua Tree Quantum Computer works as follows:
One obtains an eye-dropper and a glass of water.
One takes up a drop of water in the eye-dropper.
One drops said drop of water onto a flat piece of glass.
Immediately one achieves and observes the random pattern distribution based on the entangled interactions between the over 5.01 x 10^21 atoms (five sextillion atoms), as the combined wave function collapses and the universe splits a trillion trillion times. Using a classical computer, one would be unable to simulate this calculation even after a trillion trillion trillions years. The JT Quantum Computer leverages the entangled quantum interactions between the atoms, thusly mining the Hilbert Space of parallel universes and the multiverse in a manner that is at least several sextillion times faster than IBM's leading SUMMIT super computer.
And so the Joshua Tree Quantum Computer hath achieved quantum supremacy.
The Wright Brother's first flight lasted under a minute, and already we have crossed far further than that, with big plans for the future, and multitudinous commercial applications. A new era hath dawned.
We are currently seeking $200 million in funding to complete the design of the Redwood Quantum Computer, which will involve an entire bucket of water and which will be able to leverage the many worlds of Sean Carroll.
dx4/dt=ic friends, dx4/dt=ic :) :)
I wonder though, if it was someone from NASA or from Google that made the mistake of uploading the paper earlier than they should have.
