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 …

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 …

Quantum superpositions of macroscopically distinct classical states—so-called Schrödinger
cat states—are a resource for quantum metrology, quantum communication and quantum …

Photonic cat states stored in high-Q resonators show great promise for hardware efficient
universal quantum computing. We propose an approach to efficiently prepare such cat …

We review some of the recent efforts in devising and engineering bosonic qubits for
superconducting devices, with emphasis on the Gottesman–Kitaev–Preskill (GKP) qubit. We …

In quantum error correction, information is encoded in a high-dimensional system to protect
it from the environment. A crucial step is to use natural, two-body operations with an ancilla …

Giant atoms that interact with real-space waveguides at multiple spatial points have attracted
extensive attention due to their unique interference effects. Here we propose a feasible …

Quantum annealing aims at solving combinatorial optimization problems mapped to Ising
interactions between quantum spins. Here, with the objective of developing a noise-resilient …
