Check out our new preprint on using two-level fluctuators in Si quantum dots as temperature probes. Our community has known for a while that voltage pulses heat our qubits, but measuring temperature with a qubit can be challenging. It seems that the defects that create noise for our qubits also experience this heating, potentially offering an easier way to explore this effect.

Welcome to new graduate students Malick Gaye, Fernando Torres Leal, and Zhengyang Zhang. We are excited to have you join the group!

Our paper on using feedback to make noisy fluctuators in silicon quantum dots quieter has been published in Physical Review Applied.

Our paper on the formation of a nuclear-spin dark state in silicon has been published in Nature Physics. We show that using the electrons in quantum dots, we can drive the nuclei into a collective state with a significantly reduced interaction with the electron spins. This state has long been predicted but not observed until now!

Check out our most recent paper: an Editors’ suggestion in Physical Review B about electrical fluctuations in silicon quantum dots.

Our paper on dynamically corrected gates in singlet-triplet qubits has been published as an editors’ suggestion in Physical Review Applied. This work is a collaboration with the group of Ed Barnes at Virginia Tech. Check it out here!

Welcome to one more dilution refrigerator. The fridges are done multiplying…for a while anyway.
