Q-MPW process statistics
The published spec: ±20% junction-resistance variation across the wafer, ±10% within a block, from the Q-MPW Technical Guide. Per-round statistics will be published here, round by round.
⚑The three charts below use illustrative data. They show the format the per-round ledger will take. They are not measurements. Only the ±10% and ±20% bands are real.

Niels Bohr Institute
Runs QiB2 in its Quantum Training Lab.
We have been using the QiB2 device in the Quantum Training Lab at the Niels Bohr Institute since 2024. The device is well suited for this purpose since it allows for the evaluation of different properties of superconducting qubits.

Custom mother-machine molds; repeat customer.
We endorse them. We designed & ordered multiplex mothermachine from them about a year ago. They delivered an excellent product. The price was reasonable, certainly far less than what it cost us back in 2008 at Harvard for the first mothermachine. We will use them again.
