No-go theorems for sequential preparation of two-dimensional chiral states via channel-state correspondence
Ruihua Fan, Yantao Wu, Yimu Bao +1
We investigate whether sequential unitary circuits can prepare two-dimensional chiral states, using a correspondence between sequentially prepared states, isometric tensor network…

Phases of Floquet code under local decoherence
Yuchen Tang, Yimu Bao
Floquet code is a dynamical quantum memory with a periodically evolving logical space. As a defining feature, the code exhibits an anyon automorphism after each period, giving rise…
