Bloch sphere pronunciation
WebApr 21, 2024 · I am vexed by a particular derivation. Given a state ψ and corresponding density matrix ρ = ψ ψ , or ρ = [ a c b d], I can compute the Bloch sphere coordinates as the following (in Python): a = rho [0, 0] b = rho [1, 0] x = 2.0 * b.real y = 2.0 * b.imag z = 2.0 * a - 1.0 This code works, but - how? I fail to properly derive it. WebThe Bloch sphere (named after Felix Bloch) is a visual representation of the state of a qubit. Note that the Bloch sphere is different from the q-sphere; for more details, see the …
