Lattice-quantile estimation of Ï and convex-region integrals from coined two-dimensional quantum walks
Jen-Yu Chang, En-Jui Kuo, Chih-Yu Chen +1
Monte Carlo integration is fundamentally limited by the M^(-1/2) rate that the Cramer-Rao bound imposes on any sample-mean estimator of an expectation value, regardless of how the…

Quantum Parrondo Paradox via a Single Phase Defect Symmetry Breaking and Directed Transport
Jen-Yu Chang, Yun-Hsuan Chen, Gooi Zi Liang +2
Parrondo paradox describes the counterintuitive phenomenon in which alternating two individually losing games yields a winning outcome. Extending this effect to the quantum regime…
