TL;DR: In this article, a superconducting circuit can be used as a microwave circulator, or a directional amplifier, for nearly lossless routing and measurement of quantum microwave signals, which can have a fundamental impact on quantum measurements plus direct technological impact on current efforts to build scalable on-chip infrastructure for quantum computing.

TL;DR: In this article, a prototype device demonstrates non-reciprocity in a microwave optomechanical circuit that allows for dynamic isolation control while avoiding the need for large magnetic fields.

TL;DR: In this article, the authors used pulsed electromechanics to deterministically entangle two drumheads with masses of 70 picograms and performed quantum state tomography to observe entanglement.

TL;DR: In this paper, the authors demonstrate an efficient, frequency-converting microwave isolator based on the optomechanical interactions between electromagnetic fields and a mechanically compliant vacuum gap capacitor, achieving simultaneous reverse isolation of more than 20 dB and insertion loss less than 1.5 dB over a bandwidth of 5 kHz.

TL;DR: A new optomechanical device where the motion of a micromechanical membrane couples to a microwave resonance of a three-dimensional superconducting cavity, enabling new applications in ultrafast quantum state transfer and entanglement generation.
