Neural network enhanced cross entropy benchmark for monitored circuits
Yangrui Hu, Yi Hong Teoh, William Witczak-Krempa +1
We explore the interplay of quantum computing and machine learning to advance experimental protocols for observing measurement-induced phase transitions (MIPT) in quantum devices.…
Celestial Quantum Error Correction II: From Qudits to Celestial CFT
Alfredo Guevara, Yangrui Hu
A holographic CFT description of asymptotically flat spacetimes inherits vacuum degeneracies and IR divergences from its gravitational dual. We devise a Quantum Error Correcting (Q…
Petz map recovery for long-range entangled quantum many-body states
Yangrui Hu, Yijian Zou
Given a tripartite quantum state on and the erasure channel on , the rotated Petz map is a recovery channel that acts on to recover the erased quantum information. T…
Multiparticle Contributions to the Celestial OPE
Alfredo Guevara, Yangrui Hu, Sabrina Pasterski
We start by defining two-particle operators that appear in celestial CFT. We then show how to compute their OPE coefficients with the known single-particle operators at tree level…
Celestial Quantum Error Correction I: Qubits from Noncommutative Klein Space
Alfredo Guevara, Yangrui Hu
Quantum gravity in 4D asymptotically flat spacetimes features spontaneous symmetry breaking due to soft radiation hair, intimately tied to the proliferation of IR divergences. A ho…
Multicollinear Singularities in Celestial CFT
Adam Ball, Yangrui Hu, Sabrina Pasterski
The purpose of this paper is to study the holomorphic multicollinear limit of (celestial) amplitudes and use it to further investigate the double residue condition for (hard celest…
