TL;DR: In this article, the authors proposed a hardware-efficient instance of such a non-local qubit: a superposition of position eigenstates that forms grid states of a single oscillator.

TL;DR: The results showcase the combination of fast quantum control and robustness against errors, which is intrinsic to stabilized macroscopic states, as well as the potential of of these states as resources in quantum information processing.

TL;DR: In this article, a method for the generation and stabilization of Schr\"{o}dinger cat states based on the interplay between Kerr nonlinearity and single-mode squeezing in a superconducting microwave resonator is presented.

TL;DR: In this article, a dipole circuit element with third-order nonlinearity was proposed for a non-degenerate amplifier based on the proposed thirdorder non-linearity, which implements three-wave mixing.

TL;DR: This work experimentally prepares square and hexagonal GKP code states through a feedback protocol that incorporates non-destructive measurements that are implemented with a superconducting microwave cavity having the role of the oscillator and demonstrates QEC of an encoded qubit with suppression of all logical errors.
