Connection between single-layer quantum approximate optimization algorithm interferometry and thermal distribution sampling

Frontiers in Quantum Science and Technology
The quantum approximate optimization algorithm (QAOA) was originally proposed to find approximate solutions to combinatorial optimization problems on quantum computers. However, the algorithm has also attracted interest for sampling purposes since it was

Convergence of digitized-counterdiabatic QAOA: circuit depth versus free parameters

New Journal of Physics
Recently, digitized-counterdiabatic (CD) quantum approximate optimization algorithm (QAOA) has been proposed to make QAOA converge to the solution of an optimization problem in fewer steps, inspired by Trotterized CD driving in continuous-time quantum ...

Toward a linear-ramp QAOA protocol: evidence of a scaling advantage in solving some combinatorial optimization problems

npj Quantum Information
The quantum approximate optimization algorithm (QAOA) is a promising algorithm for solving combinatorial optimization problems (COPs), with performance governed by variational parameters $${\{{\gamma }_{i},{\beta }_{i}\}}_{i = 0}^{p-1}$$ { γ i , β i } i =
