Description
SLAC National Accelerator Laboratory hosts the LCLS-II, a 700-meter LINAC supported by two large 4 kW @ 2.0 K cryoplants. Located in Menlo Park, on the Stanford University campus in the heart of Silicon Valley, a hub for groundbreaking advancements in quantum technologies, which often rely on cryogenic temperatures. PsiQuantum, headquartered in Palo Alto just a few miles from SLAC, employs a unique photonics-based quantum computing technology that operates at cryogenic temperatures. Through a Cooperative Research and Development Agreement (CRADA), SLAC and PsiQuantum have partnered to integrate PsiQuantum’s test facility with SLAC’s advanced cryogenic infrastructure. The CRADA includes providing cryogenic capabilities ranging from 100 W to 300 W at 2.4 K. This collaboration enabled PsiQuantum to establish a fully operational cryogenic facility in just one year — a timeline that would have otherwise exceeded two years. This paper provides an overview of the partnership, focusing on the integration process, commissioning efforts, and challenges encountered.
