Hybrid Quantum Devices

For applications such as storing quantum states with rapid access, linking remote quantum processors or sensing sound at the quantum limit, quantum hybrids combine two or more physical systems that can achieve more than the individual components alone. Interfacing different quantum degrees of freedom leads to new techniques and a better understanding of fundamental physics.

This Special Topic aims to provide researchers working in the field and students learning about the field, with an informed set of papers collating state-of-the-art developments in hybrid quantum systems and devices, and the challenges ahead. This important collection of papers will strengthen connections between atomic and condensed matter physics and quantum optics and nanoscience. We welcome papers that highlight recent developments, potentially disruptive technologies, and possible future solutions.

Topics covered include, but are not limited to:

• Atomic, photonic or solid-state components interfaced with each other
• Physics of current hybrid quantum devices and new hybrid prospects
• Quantum-nonlinear (qubits or few-level systems) and quantum ground state (small thermal occupation) hybrids
• Applications opportunities for quantum communication, metrology, and sensing
• Quantum engineering of hybrid circuits and devices
• Material physics, and leading developments related to nanofabrication challenges and processing of hybrid circuits and devices
