Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Reciprocity is a fundamental principle in optics, requiring that the response of a transmission
channel is symmetric when source and observation points are interchanged. It is of major …

We reveal the cooperative effect of coherent and dissipative magnon-photon couplings in an
open cavity magnonic system, which leads to nonreciprocity with a considerably large …

We propose how to create and manipulate one-way nonclassical light via photon blockade
in rotating nonlinear devices. We refer to this effect as nonreciprocal photon blockade (PB) …

In superconducting quantum computing, qubit state information is conveyed via low-power
microwave fields. As such, ultralow-noise microwave amplification plays a central role in …

Delivering on the revolutionary promise of a universal quantum computer will require
processors with millions of quantum bits (qubits),–. In superconducting quantum processors …

The performance of superconducting circuits for quantum computing is limited by materials
losses. In particular, coherence times are typically bounded by two-level system (TLS) …

Chirality or handedness distinguishes an object from its mirror images, such as the spread
thumb, index finger, and middle finger of the right and left hand. In mathematics, it is …

Fast, high-fidelity operations between microwave resonators are an important tool for
bosonic quantum computation and simulation with superconducting circuits. An attractive …
