Emerging Qubit Systems – Novel Materials, Encodings and Architectures
Over the past 20 years, tremendous progress has been made in developing small scale quantum processors, with qubits established in a variety of physical systems. While the most mature quantum architectures are becoming competitive with classical computers in certain contexts, some of the nascent technologies have advantages that could eventually lead them to becoming dominant in the future.
This special topic is dedicated to these emerging qubit systems with a focus on enabling technologies. We welcome papers that facilitate new lines of research by laying the groundwork for future devices or approaches to quantum information processing. This includes not only new, but also existing qubit device designs, provided there is some novel aspect to the qubit implementation. This includes, but is not limited to new and emerging materials, qubit encodings, and device architectures.
Topics covered include, but are not limited to:
- Superconductor and Josephson junction materials
- Superconducting qubit circuit design
- Host materials for electron and nuclear spin qubits
- Color centers and atom-like defects in semiconductors
- Trapped ions, neutral atoms, and molecules
- Integrated quantum photonics
- Quantum devices in 2D materials
- Protected qubit encodings (topologically protected qubits, time crystal phases, or many body states)
- Novel architectures
- Techniques for the rapid screening and prototyping of qubit materials and devices
