Hierarchy of Rényi Coherent Information in Stabilizer Codes
Akash Vijay, Luis Colmenarez, Jong Yeon Lee
Rényi coherent information, a computable proxy for the von Neumann coherent information, is widely used to study mixed-state phases of matter and decodability transitions in noisy…
Approximate Quantum Error Correction at Chiral Topological Edges
Yuntai Song, Zejun Liu, Zhencheng Wang +2
Topologically ordered phases naturally realize quantum error correction through nonlocal encoding of quantum information. More recently, conformal field theories have been shown to…
Lifting Lifted Product Codes
Yuta Hirasaki, Jong Yeon Lee
Lifted product (LP) codes form an important class of quantum error correcting codes with favorable code parameters. We introduce a systematic construction of LP code families based…
Logical Spectroscopy: Lifted-Product Codes with Addressable Bases
Jong Yeon Lee
Quantum LDPC memories can encode many logical qubits, but that alone does not make them usable: applications need to know where the logical operators are supported, how they are la…
Liouvillian Gap in Dissipative Haar-Doped Clifford Circuits
Ha Eum Kim, Andrew D. Kim, Jong Yeon Lee
Quantum chaos is commonly assessed through probe-dependent signatures that need not coincide. Recently, a dissipative signature was proposed for chaotic Floquet systems, where infi…
Information Critical Phases under Decoherence
Akash Vijay, Jong Yeon Lee
Quantum critical phases are extended regions of phase space characterized by a diverging correlation length. By analogy, we define an \emph{information critical phase} as an extend…
Holographically Emergent Gauge Theory in Symmetric Quantum Circuits
Akash Vijay, Jong Yeon Lee
We develop a novel holographic framework to study dynamical phases in random quantum circuits with a global symmetry . Viewing the circuit as a tensor network, we decompose it i…
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…
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…
Stable measurement-induced Floquet enriched topological order
DinhDuy Vu, Ali Lavasani, Jong Yeon Lee +1
The Floquet code utilizes a periodic sequence of two-qubit measurements to realize the topological order. After each measurement round, the instantaneous stabilizer group can be ma…
Practical variational tomography for critical 1D systems
Jong Yeon Lee, Olivier Landon-Cardinal
We improve upon a recently introduced efficient quantum state reconstruction procedure targeted to states well-approximated by the multi-scale entanglement renormalization ansatz (…
