Charge-Informed Quantum Error Correction
Vlad Temkin, Zack Weinstein, Ruihua Fan +2
We investigate the statistical physics of quantum error correction in symmetry-enriched topological quantum memories. Starting from a phenomenological error model of c…
Probing chiral topological states with permutation defects
Yarden Sheffer, Ruihua Fan, Ady Stern +2
The hallmark of two-dimensional chiral topological phases is the existence of anomalous gapless modes at the spatial boundary. Yet, the manifestation of this edge anomaly within th…
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…
Visualizing interaction-driven restructuring of quantum Hall edge states
Jiachen Yu, Haotan Han, Kristina G. Wolinski +10
Many topological phases host gapless boundary modes that can be dramatically modified by electronic interactions. Even for the long-studied edge modes of quantum Hall phases, formi…
Fractional quantum Hall states under density decoherence
Zijian Wang, Ruihua Fan, Tianle Wang +2
Fractional quantum Hall states are promising platforms for topological quantum computation due to their capacity to encode quantum information in topologically degenerate ground st…
Entropy of strongly correlated electrons in a partially filled Landau level
Alexandre Assouline, Taige Wang, Heun Mo Yoo +7
We use high-resolution chemical potential measurements to extract the entropy of monolayer and bilayer graphene in the quantum Hall regime via the Maxwell relation $\left.\frac{dμ}…
A Universal Circuit Set Using the Quantum Double
Liyuan Chen, Yuanjie Ren, Ruihua Fan +1
One potential route toward fault-tolerant universal quantum computation is to use non-Abelian topological codes. In this work, we investigate how to achieve this goal with the quan…
Designing exciton-condensate Josephson junction in quantum Hall heterostructures
Tianle Wang, Ruihua Fan, Zhehao Dai +1
The exciton condensate (EC), a coherent state of electron-hole pairs, has been robustly realized in two-dimensional quantum Hall bilayer systems at integer fillings. However, direc…
