Slepian Bounds on the Success Probability of Virtual Distillation
Masayuki Ohzeki, Sasuke Kimata, Xinwei Lee +1
Virtual distillation is a powerful near-term error-mitigation primitive, but it is also a spectral filter: it amplifies the dominant eigenvector component already present in the no…
Coherent Quantum Schrodinger Bridge: Two-Boundary Optimal Control for Quantum Algorithm Design
Masayuki Ohzeki
Quantum algorithms are intrinsically two-boundary processes: an input state is prepared, and an output state or subspace is selected as the computational answer. We formulate this…
Attention-Like Hebbian Learning from Quantum Probability Flow and Quantum-Annealer Tests
Masayuki Ohzeki
We propose a quantum probability-flow principle for deriving local learning rules in associative memory. A transverse field defines leakage channels from data states, and minimizin…
A Minimal Duality Estimate for the Surface-Code Threshold under Nearest-Neighbor Correlated Errors
Masayuki Ohzeki
We apply the single-equation duality criterion to the square-octagonal random-bond Ising model recently obtained from an exact error-edge map for a surface code with nearest-neighb…
Analytical Singular-Value Structure of Analytic-Continuation Kernels from Slepian Information Theory
Masayuki Ohzeki
Analytic continuation from imaginary-time Green's functions to real-frequency spectra is a central ill-posed inverse problem in quantum many-body physics. We show that the thermal…
Duality analysis in symmetric group and its application to random tensor network model
Masayuki Ohzeki
The Ising model is the simplest to describe many-body effects in classical statistical mechanics. Duality analysis leads to a critical point under several assumptions. The Ising mo…
