Microwave photonics with superconducting quantum circuits
TL;DR: In the past 20 years, impressive progress has been made both experimentally and theoretically in superconducting quantum circuits, which provide a platform for manipulating microwave photons as mentioned in this paper, and many higher-order effects, unusual and less familiar in traditional cavity quantum electrodynamics with natural atoms, have been experimentally observed.

Measurement-based quantum control of mechanical motion
TL;DR: In this article, an optomechanical transducer resolves the zero-point motion of a millimetre-sized membrane resonator in a fraction of its millisecond-scale coherence time, with an overall measurement efficiency close to unity.
Journal ArticleDOI
Nonreciprocal Photon Blockade.
TL;DR: This work shows that in a spinning Kerr resonator, PB happens when the resonator is driven in one direction but not the other, leading to a full split of the resonance frequencies of the countercirculating modes.

Decoherence-Free Interaction between Giant Atoms in Waveguide Quantum Electrodynamics
TL;DR: This work shows that the giant atoms can be protected from decohering through the waveguide, but still have exchange interactions mediated by the wave guide, and shows how this decoherence-free interaction can be designed in setups with multiple atoms to implement, e.g., a 1D chain of atoms with nearest-neighbor couplings or a collection of atom with all-to-all connectivity.

Robust and Optimal Control
TL;DR: This paper reviewed the history of the relationship between robust control and optimal control and H-infinity theory and concluded that robust control has become thoroughly mainstream, and robust control methods permeate robust control theory.
