I've been digging into QC for the past few months, trying to get to the bottom of the stack and learn exactly how things work. I've concluded that Qubits are best viewed as an (X,Y,Z) vector with a length of one. For some reason |0> is (0,0,1) and |1> is (0,0,-1), and most operations involve rotations around an axis that always goes through (0,0,0) Quantum supremacy seems to require that these states have no noise, and especially no coupling between qubits. Quantum Error Correction at first blush appears to be a way out, but only corrects errors by pushing Qubits back to a superposition of |0> and |1>, and throwing away X and Y values. In order for things like Shor's algorithm to work, you have to be able to make many rotations around the line half way between the X and Z axis (a Hadamard gate). Additionally, you have to make very small angle rotations for the Inverse Quantum Fourier Transform, and phase errors stack up. I welcome any and all corrections to this interpretation of things.
