Just as “classical” information technology rests on a foundation built of interconnected
information-processing systems, quantum information technology (QIT) must do the same. A …

The generation of high-fidelity distributed multi-qubit entanglement is a challenging task for
large-scale quantum communication and computational networks,,–. The deterministic …

Superconducting circuits are a strong contender for realizing quantum computing systems
and are also successfully used to study quantum optics and hybrid quantum systems …

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 …

We demonstrate a superconducting artificial atom with strong unidirectional coupling to a
microwave photonic waveguide. Our artificial atom is realized by coupling a transmon qubit …

We propose tunable chiral bound states in a system composed of superconducting giant
atoms and a Josephson photonic-crystal waveguide (PCW), with no analog in other …

Superconducting qubits in a waveguide have long-range interactions mediated by photons
that cause the emergence of collective states. Destructive interference between the qubits …

Radio-frequency communication systems have long used bulk-and surface-acoustic-wave
devices supporting ultrasonic mechanical waves to manipulate and sense signals. These …

Skyrmions with topologically stable configuration have shown a promising route toward high-
