TL;DR: The results demonstrate that Josephson quantum computing is a high-fidelity technology, with a clear path to scaling up to large-scale, fault-tolerant quantum circuits.

TL;DR: The protection of classical states from environmental bit-flip errors is reported and the suppression of these errors with increasing system size is demonstrated, motivating further research into the many challenges associated with building a large-scale superconducting quantum computer.

TL;DR: This work demonstrates a planar, tunable superconducting qubit with energy relaxation times up to 44 μs and finds a fine structure in the qubit energy lifetime as a function of frequency, indicating the presence of a sparse population of incoherent, weakly coupled two-level defects.

TL;DR: A superconducting qubit architecture that combines high-coherence qubits and tunable qubit-qubit coupling that can be tuned dynamically with nanosecond resolution is introduced, making this architecture a versatile platform with applications ranging from quantum logic gates to quantum simulation.

TL;DR: In this article, a digital quantum simulation of the adiabatic algorithm is presented, which consists of up to nine qubits and up to 1,000 quantum logic gates and can solve random instances of the one-dimensional Ising problem as well as problem Hamiltonians that involve more complex interactions.
