–Quantum mechanics is an inherently linear theory. However, collective effects in many body quantum systems can give rise to effectively nonlinear dynamics. In the present work, we analyze whether and to what extent such nonlinear effects can be exploited to enhance the rate of quantum evolution. To this end, we compute a suitable version of the quantum speed limit for numerical and analytical examples. We find that the quantum speed limit grows with the strength of the nonlinearity, yet it does…

Nonlinear and non-CP gates for Bloch vector amplification

Any state r = ( x, y, z ) of a qubit, written in the Pauli basis and initialized in the pure state r = (0 , 0 , 1), can be prepared by composing three quantum operations: two unitary rotation gates
