–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… Expand

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… Expand
