WebThe std::all_of () function is a STL Algorithm in C++. It can be used to check if all the elements of a sequence satisfies a condition or not. The sequence can be a vector, array, list or any other sequential container. We need to include the header file to use the std::all_of () function. WebGenerate the vector for the input Ψ in = 00. .0 ( n zeros ). This is a quantum state and quantum states are represented in your program by a 2 n size vector where n is the number of wires. Multiply the vector Ψ in by U circuit. This gives you the output quantum state Ψ out . Measure the final quantum state Ψ out .
