Adiabatic tracking and optimal schedules for classical and quantum Gibbs-state preparation

Pedro C. S. Costa, Mauro E. S. Morales, Dong An +1

We develop a discrete adiabatic framework for Gibbs-state preparation in classical and quantum optimisation algorithms. For finite time-inhomogeneous reversible Markov chains, we d…

Constant Factor Analysis of Optimal Quantum Linear Solvers in Practice

Pedro C. S. Costa, Alexander M. Dalzell, Dong An +1

Optimal quantum linear equation solvers provide complexity $O (κ lo g (1/ ε))$ , where $κ$ is the condition number and $ε$ is the allowable error. The optimal solver using a discrete ad…
