Cryogenic and Strong-Field Infrastructure

Cryogenic and Strong-Field Infrastructure

Low-temperature and magnetic-field environments for long-coherence measurements, ZEFOZ studies, and benchmarking solid-state quantum memories.

These systems make it possible to probe long-lived storage, extend coherence with dynamical decoupling, and evaluate rare-earth memory performance under controlled cryogenic conditions.

  • Vacuum cryostat
  • Low-temperature strong magnetic platform
  • Vector field dilution refrigerator
Materials Preparation and Device Screening

Materials Preparation and Device Screening

Laboratory space for exploring new rare-earth crystals, polycrystalline platforms, and sample-development routes linked to quantum memory.

This environment supports the transition from new material discovery to spectroscopic evaluation, helping SSQS identify hosts with broader bandwidth, longer coherence, and lower noise.
