Like Rubik's Cube, but Quantum. Become a master single-qubit gates.
This is a basic problem to get you started with one-qubit quantum circuit operations using QASM.
To solve this RubiQ's Sphere problem, you need to rotate the state so it reads with probability when ran regularly for more than 10 iterations
To make it simpler, know that the solution will be just a combination of the following gates.
z qubit; // pi rotation about the Z-axis x qubit; // pi rotation about the X-axis y qubit; // pi rotation about the Y-axis h qubit; // The combination of two rotations, pi about the Z-axis followed by pi/2 about the Y-axis s qubit; // S-gate, square root of Z gate sdg qubit; // conjugate of S-gate t qubit; // Phase-gate, conjugate of square root of S-gate tdg qubit; // conjugate of Phase-gate
Do some trial error mixing them up, until you get the solution!
