Depth-Efficient Quantum Topological Data Analysis for Regime-Specific Detection of Financial Stress
Arul Rhik Mazumder, Shreyan Ronit Mazumder
We present, to our knowledge, the first adaptation of Pauli Correlation Encoding (PCE) to quantum topological data analysis, reformulating Betti number estimation as a depth-efficient variational optimization over a compressed qubit register. From a Takens embedding and Vietoris-…
