Our Roots

The First Dilution Fridge
Prior to the establishment of the DOE AQT program, LBNL internal investments seeded the acquisition of a large, 1000 microwatt dilution refrigerator targeting full control of 128 qubits. This tool is the main instrument accessible to DOE users of the AQT, and is fully capable of remote operation. The current hardware configuration involves the parallel operation of multiple processor architectures to explore a larger design and application tradespace.

To house the house the hardware and diverse AQT research team under one room, LBNL is renovating B73 to be a central hub for quantum information related activities. The building has precision temperature control, electromagnetic shielding, and custom infrastructure for quantum computing research. The collaborative meeting office and meeting spaces provide an interactive workspace for local scientists and current users visiting the AQT.

B73 Innaguration

The Building 73 quantum complex is scheduled for move in late fall. Tools currently housed at UC Berkeley will be transported in phases. New fridges already being fabricated will be installed.
