Welcome to one of our quantum computing labs. Right over here's one
of our dilution refrigeration systems which actually cools down
our superconducting qubit devices. There are a number of different
plates inside here which all at different temperatures.
That gets down to 15 millikelvin. That's colder than outer space, itself.
The sound you hear is actually a pulse tube compressor,
which essentially is pumping on a closed cycle of helium 4,
which helps us get the system cold. We have a lot of other
equipment that we used in order to run the processors.
So, there's a lot of microwave hardware, different passive
components including filters and attenuators, as as well as
cloxial cables which allow us to send the signals down to
address the qubits and to read them out. Giving us the controlability.
This is a four cubic package. We have a five qubit
device that's right now inside the fridge but the general
idea for how we actually package of these devices and cool them
down is the same. And this is a printed circuit board to
which we mount our qubit chips and we wire bond to them
connect to essentially these coaxial pins
and these coaxial pins connect to cables which are
inside of the fridge to allow us to send the signal is down and
to take signals back and read them out
