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 …

The aim of this review is to provide quantum engineers with an introductory guide to the
central concepts and challenges in the rapidly accelerating field of superconducting …

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

Encoding a qubit in a high-quality superconducting microwave cavity offers the opportunity
to perform the first layer of error correction in a single device but presents a challenge: how …

We report on the design and implementation of a field-programmable Josephson amplifier
(FPJA)—a compact and lossless superconducting circuit that can be programmed in situ by …

Generation of entanglement between spatially separated macroscopic systems enables
quantum networks and fundamental tests of quantum theory. Here, we propose a scheme to …

Qubit connectivity is an important property of a quantum processor, with an ideal processor
having random access—the ability of arbitrary qubit pairs to interact directly. This a …

We autonomously stabilize arbitrary states of a qubit through parametric modulation of the
coupling between a fixed frequency qubit and resonator. The coupling modulation is …

The quantum router is an elementary building block in quantum information processing and
quantum communication. This work constitutes a step forward in this direction, ie, an efficient …

A current bottleneck for quantum computation is the realization of high-fidelity two-qubit
quantum operations between two or more quantum bits in arrays of coupled qubits. Gates …
