I’m a Co-I on one of each and there is no “guidance” just a vague stop work order at the labs. The campus grants are proceeding as normal for now but it’s unclear if the money will actually materialize

This is the most fraught transition I have personally experienced. I am stressed but focused on trying to keep in mind that being stressed/discouraged is part of their goal. We need to keep in working as if there’s not a toddler in the White House throwing a tantrum.

Some places have pre-emptively stopped research activities (looking at you UChicago). Reach out to your administration and ask them to demand clearer guidance from program managers and agency management before they have knee-jerk reactions

Some more nice photos removing our vacuum shields of the cryostat (cryo shields had already been taken off). Jacqueline Orrell/SLAC National Laboratory

More thoughts on this tomorrow. Our group is presenting new results where we can replicate the same quasiparticle poisoning in simpler qubit-derived superconducting devices - we are using these as sensors and in the process aiming to learn more about mitigating or enhancing these couplings.

A paper that succinctly explores the interactions of qubits with pair-breaking radiation can be found here: arxiv.org/abs/2203.06577. Note the main point that the baseline poisoning is correlated most strongly with the resonant mode volume of the qubit.
Quasiparticle Poisoning of Superconducting Qubits from Resonant Absorption of Pair-breaking Photons
The ideal superconductor provides a pristine environment for the delicate states of a quantum computer: because there is an energy gap to excitations, there are no spurious modes with which the qubits...

One of the key issues in quantum computing is illustrated here - how does one isolate a system enough that it can thermalize entirely while still interacting with it? While we can do fairly well, we need better solutions to limit pair breaking radiation in our readout lines.

In particular, the ability to elucidate multiple energy scales relevant to thermal and poisoned tunneling helps show how strongly athermal this effect is. It’s interesting that the rate in the excited state does not plateau in the same way as the ground state.
