A Hybrid Quantum-Classical Algorithm for Underwater Target Classification

Algorithm 1

Hybrid quantum-classical classification algorithm.

	Require: Sample matrix where row is .
	Ensure: Predicted label .
	(1) solve the first singular values of the matrix using eigensolver.
	(2) for j = 1 to M + 1 do
	(3) prepare initial state .
	(4) for k = 1 to R do
	(5) construct operator where , and apply it on .
	(6) estimate the amplitude of state and obtain .
	(7) end for
	(8) end for
	(9) use classical classifier to predict the label of .
