Decoupling 2D translation-invariant topological CSS codes
Yifei Wang, Zhongyi Ni, Mingxin He +2
Two-dimensional translation-invariant topological CSS codes on qubits are known to be locally equivalent, after coarse-graining, to stacks of toric codes. However, existing constru…
Unleashing Emergent Fermions with Rydberg Atom Simulators
Hanteng Wang, Xingyu Li, Shang Liu +2
Rydberg atom simulators, in both analog and digital modes, have attracted significant recent interest due to their versatile geometric reconfigurability. In this work, leveraging t…
Resolving spurious topological entanglement entropy in stabilizer codes
Peilun Han, Zijian Liang, Yifei Wang +3
Topological entanglement entropy (TEE) is a key diagnostic of long-range entanglement in two-dimensional gapped phases of matter, but it can suffer from spurious contributions that…
Magic teleportation with generalized lattice surgery
Yifei Wang, Yingfei Gu
We propose a novel, distillation-free scheme for the fault-tolerant implementation of non-Clifford gates at the logical level, thereby completing the universal gate set. Our approa…
Lattice Defects in Rydberg Atom Arrays
Hanteng Wang, Chengshu Li, Xingyu Li +2
Rydberg atom arrays have become a key platform for studying quantum many-body systems. In these setups, defects arise naturally due to various imperfections and can significantly m…
Uncovering Emergent Spacetime Supersymmetry with Rydberg Atom Arrays
Chengshu Li, Shang Liu, Hanteng Wang +4
In the zoo of emergent symmetries in quantum many-body physics, the previously unrealized emergent spacetime supersymmetry (SUSY) is particularly intriguing. Although it was known…
