TL;DR: Quantum supremacy is demonstrated using a programmable superconducting processor known as Sycamore, taking approximately 200 seconds to sample one instance of a quantum circuit a million times, which would take a state-of-the-art supercomputer around ten thousand years to compute.

TL;DR: Several quantum simulations of chemistry with up to one dozen qubits are performed, including modeling the isomerization mechanism of diazene, and error-mitigation strategies based on N-representability that dramatically improve the effective fidelity of the experiments are demonstrated.

Stabilizing Rabi oscillations in a superconducting qubit using quantum feedback
R. Vijay,C. Macklin,Daniel H. Slichter,Daniel H. Slichter,S. J. Weber,Kater Murch,Ravi Naik,Alexander N. Korotkov,Irfan Siddiqi +8 more
TL;DR: In this paper, a superconducting quantum bit (qubit) coupled to a microwave cavity is used to stabilize the oscillation phase of a driven quantum bit, which can be used to continuously track and steer the quantum state using feedback.
