From the Shastry-Sutherland model to the - Heisenberg model
Xiangjian Qian, Rongyi Lv, Jong Yeon Lee +1
We propose a generalized Shastry-Sutherland model which bridges the Shastry-Sutherland model and the - Heisenberg model. By employing large scale Density Matrix Renormali…
Error Threshold of SYK Codes from Strong-to-Weak Parity Symmetry Breaking
Jaewon Kim, Ehud Altman, Jong Yeon Lee
Quantum error correction (QEC) codes are fundamentally linked to quantum phases of matter: the degenerate ground state manifold corresponds to the code space, while topological exc…
Coherent information for CSS codes under decoherence
Ryotaro Niwa, Jong Yeon Lee
Stabilizer codes lie at the heart of modern quantum-error-correcting codes (QECC). Of particular importance is a class called Calderbank-Shor-Steane (CSS) codes, which includes man…
Tensor network formulation of symmetry protected topological phases in mixed states
Hanyu Xue, Jong Yeon Lee, Yimu Bao
We define and classify symmetry-protected topological (SPT) phases in mixed states based on the tensor network formulation of the density matrix. In one dimension, we introduce str…
Exact Calculations of Coherent Information for Toric Codes under Decoherence: Identifying the Fundamental Error Threshold
Jong Yeon Lee
The toric code is a canonical example of a topological error-correcting code. Two logical qubits stored within the toric code are robust against local decoherence, ensuring that th…
An architecture for two-qubit encoding in neutral ytterbium-171 atoms
Zhubing Jia, William Huie, Lintao Li +7
We present an architecture for encoding two qubits within the optical "clock" transition and nuclear spin-1/2 degree of freedom of neutral ytterbium-171 atoms. Inspired by recent h…
