Symposium MQ02—Materials for Quantum Computing Applications

The operation of quantum computing hardware requires an extremely low-noise, low-dissipative environment to maintain quantum coherence of the qubits as the signals for the computation are at the single-photon energy level. For example, ion-trap qubits require ultra-high vacuum to maintain the coherence of motional states that couple the ion qubits in the trap. Most solid-state qubits such as superconducting qubits, quantum-dots and spins must be made of low-loss high quality (Q) factor materials with low defects. Many of these qubits must be operated at very low-temperatures to suppress thermal noise effects. The materials for quantum computing applications need to function as intended at such extreme environments as well as to be low-noise, low-dissipative for high quantum coherence.

The technologies to build various quantum computing hardware platforms have advanced significantly over the past two decades. The importance of quantum-computing qualified materials has never been higher as quantum processors are scaling up and becoming more integrated. To move forward to the next generation quantum computing processors, ongoing research in the area of materials for quantum computing devices must continue.

This symposium will bring together experts on various quantum computing hardware materials across industry, academia and national laboratories. The symposium is to promote exchanging information among researchers, catalyze discovery, development of new materials, and improve existing material qualities for quantum computing applications. We hope this workshop will provide information to material scientists who want to learn more about quantum computing hardware and challenges as well as inform quantum information scientists about new material opportunities.

Invited talks will review the history, cutting-edge status of quantum material research, including the requirements, goals and roadmaps of the material development for each quantum hardware platform.

Topics will include:

  • High-Q dielectric films and substrates for qubits at microwave frequencies
  • Materials for micro-fabricated/on-chip ion trap qubits
  • Materials to mitigate quasiparticles in superconducitng qubits
  • Ultra-high purity materials/substrates for spin qubits and color-centers
  • Materials for topological qubits
  • Device materials and substrates for quantum dot qubits
  • Novel material characterization methods: experiments and modeling
  • Novel device fabrication methods
  • Theory and modeling of the coherence properties of quantum devices
  • Theory and modeling of quantum computing device design
  • Novel josephson junctions and circuit elements for quantum computing applications
  • Interactions between qubits and spins in materials
  • A tutorial complementing this symposium is tentatively planned.
