Constraining the Progenitor Orbits of Sequential Black-Hole Mergers in Hierarchical Triples: Peters-Based Estimates

Felix M. Heinze, Zhoujian Cao

Two black-hole merger events may originate from sequential mergers in a pre-existing hierarchical black-hole triple if their spatial localizations overlap and the remnant mass of t…

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…

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…

Charge Scrambling in Strong-to-Weak Spontaneous Symmetry Breaking

Jong Yeon Lee

Strong-to-weak spontaneous symmetry breaking (SWSSB) is diagnosed by nonlinear correlators, but its direct static implication for conserved charge fluctuations is not automatic. We…

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…

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…
