10 Nov 2015 | | Abstract: | We introduce a shortcut to the adiabatic gate teleportation model of quantum
computation. More specifically, we determine fast local counter-diabatic
Hamiltonians able to implement teleportation as a primitive for universal
quantum computing. In this scenario, we provide the counter-diabatic driving
for arbitrary n-qubit gates, which allows to achieve universality through a
variety of gate sets. Remarkably, our approach maps the superadiabatic
Hamiltonian for an arbitrary n-qubit gate teleportation into the implementation
of a rotated superadiabatic dynamics of an n-qubit state teleportation. This
result is rather general, with the speed of the evolution only dictated by the
quantum speed limit. In particular, we analyze the energetic cost for different
Hamiltonian interpolations in the context of the energy-time complementarity. | | Source: | arXiv, 1511.3301 | | Services: | Forum | Review | PDF | Favorites | |
