Grover search algorithm circuits. Grover search algorithm implementation by substage using XX(χ), R x (θ), R y (θ), and R(θ, ϕ) gates. The circuits shown are for use with Boolean oracles; removing the ancilla qubit |q a〉 produces the necessary circuits for use with a phase oracle. Let α = sgn(χ 12), β = sgn(χ 1t), γ = sgn(χ 2t), and \(P = {\mathrm{arcsin}}{\kern 1pt} \left( {\sqrt {{\textstyle{2 \over 3}}} } \right)\). a Grover initialization stage implementation. b Grover amplification stage implementation
