Fusion-assisted decoding of non-Abelian topological order
Rohith Sajith, Yabo Li, Zijian Song +2
Maximum likelihood (ML) decoders perform quantum error correction by measuring a set of syndromes, classically computing an optimal recovery based on these syndromes and the noise…
Mixed-state phases induced by power-law quantum channels
Christopher Fechisin, Tsung-Cheng Lu, Zhi-Yuan Wei +4
Open quantum systems can exhibit inherently mixed quantum orders, such as strong-to-weak spontaneous symmetry breaking (SW-SSB), which have no analogue in pure states. It is genera…
State preparation via measurement and feedback: pushing relations, state structures, and non-invertible symmetries
Yabo Li, Aditi Mitra, Tsung-Cheng Lu
Quantum circuits with measurements and unitary feedback (MF) can prepare long-range entangled states in constant depth, but a systematic construction of the MF preparation circuit…
Mixed-State Long-Range Entanglement from Dimensional Constraints
Leonardo A. Lessa, Tsung-Cheng Lu
We present a new mechanism for long-range entanglement (LRE) in strongly symmetric many-body mixed states that does not rely on symmetry anomalies or long-range correlations. Our p…
Higher-form anomaly and long-range entanglement of mixed states
Leonardo A. Lessa, Shengqi Sang, Tsung-Cheng Lu +2
In open quantum systems, we directly relate anomalies of higher-form symmetries to the long-range entanglement of any mixed state with such symmetries. First, we define equivalence…
Non-onsite symmetry breaking: topological phase coexistence and criticality
Zhehao Zhang, Yabo Li, Tsung-Cheng Lu
We explore the states of matter arising from the spontaneous symmetry breaking (SSB) of non-onsite symmetries. In one spatial dimension, we construct a frustration-f…
