The paper was called "Quantum supremacy using a programmable superconducting processor" and was available at [1] but is now removed.
I also found a partial abstract [2]: "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 2^53 ~ 10^16. Measurements fro…"
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 [3].

- bill_mcgonigle 7y agoA little more for you: "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 http://hdl.handle.net/2060/20190030475 CASI application/pdf Mandra, Salvatore Rieffel, Eleanor G.
