Error-correcting codes in the qLDPC family use far fewer physical qubits than the surface code, but their error checks connect qubits that sit far apart — and on neutral-atom hardware that distance is paid for by physically carrying atoms across the array, which is slow. We took one fixed code, the [[144,12,12]] bivariate bicycle code,…

 Please join us in welcoming Ben Miller, a visiting scientist from the U.S. Army Research Laboratory (ARL). Ben will be working with the group to develop simulation infrastructure for neutral-atom quantum computing. Welcome, Ben!

 We’ve trapped our first rubidium atoms in 3D! Congratulations to Ohik on the group’s first magneto-optical trap!

 Congratulations to Victor, who completed his MS last month and has generously stayed on to help finish up software for dynamical decoupling pulse scheduling. Victor joined the NV project as an undergraduate after taking EE400Q with Kai-Mei, and went on to author a paper on precise RF pulse control of NV quantum memories — recently…

We hosted dozens of 4th – 8th grade students during Discovery Days, to play around with our dust trap. This planar Paul trap (technology invented here at UW) traps lycopodium moss spores in precisely the same way single atomic ions are trapped for quantum computing.

At quantum testbed lab, researchers across the UW probe ‘spooky’ mysteries of quantum phenomena
