Welcome to QUBIT Lab
A small lab that builds superconducting qubits, protects them with error-correcting codes and runs useful algorithms on them.

From the professor
A qubit is a promise to remember a state that nature would rather forget. Our work is to make that promise last a little longer each year.
QUBIT Lab started in 2019 with one dilution refrigerator and two students. Today fourteen researchers design and fabricate transmon chips, write decoders that catch errors as they happen, and test small algorithms that tell us whether the hardware is getting better in ways that matter.
We like problems where a device, a code and an algorithm all have to agree. If that sounds like your kind of puzzle, write to us — collaborators and visiting students are always welcome.
