Gate-Efficient Implementation of the Query-Optimal Time-Dependent Hamiltonian Simulation

The query-optimal algorithm of [CGWZ26] for general time-dependent Hamiltonian simulation uses $$ q = O\left( \alpha T + \frac{\log(1/\varepsilon)}{\log\left(e + \log(1/\varepsilon)/(\alpha T) \right)} \right) $$ queries to $\mathrm{HAM\mbox{-}T}$ within $\varepsilon$ error for a Lipschitz-continuous time-dependent Ham...

Quantum Algorithm for Elliptic Curve Discrete Logarithms with Space-Efficient Point Addition

A new space-efficient reversible modular inversion circuit is presented, which addresses the dominant space bottleneck in affine-coordinate point addition and provides a space-efficient controlled affine point-addition circuit and a complete implementation of Shor's algorithm for ECDLP.
