::<math>(\langle+|Z^{m_1}\otimes\langle+|Z^{m_2}\otimes I)CZ_{1,3}CZ_{2,4}(|\phi\rangle\otimes CZ|+\rangle^{\otimes 2})=\frac{1}{2}CZ(HZ^{m_1}\otimes HZ^{m_2})|\phi\rangle</math>.
 
for measurement outcomes <math>m_1</math> and <math>m_2</math>. This basic concept extends to arbitrarily many qubits, and thus computation is performed by the byproduct operators of teleportation down a chain. Adjusting the desired single-qubit gates is simply a matter of adjusting the measurement basis on each qubit, and non-Pauli measurements are necessary for universal quantum computation.
