Quantum Gate Visualisation

A few tools to help with the visualization of quantum gates and Bloch vectors

Based on this contribution, these few files helps understand the Pauli rotations/unitary matrices used in the gates of quantum computing.

The traceGate function is the most useful - call it without arguments for a short animation of the identity .

% A bunch of primatives to use
ket0 = [1; 0], ket1 = [0; 1]
bra0 = ket0', bra1 = ket1'
I = eye(2)
X = [0 1; 1 0], Y = [0 -1j; 1j 0], Z = [1 0; 0 -1]
H = 1/sqrt(2)*hadamard(2)
S = [1 0; 0 1j]
T = [1 0; 0 exp(1j*pi/4)]
