Holonomic Quantum Computation
Paolo Zanardi, Mario Rasetti
abstract: We show that the notion of generalized Berry phase i.e., non-abelian
holonomy, can be used for enabling quantum computation. The computational space
is realized by a $n$-fold degenerate eigenspace of a family of Hamiltonians
parametrized by a manifold $\cal M$. The point of $\cal M$ represents classical
configuration of control fields and, for multi-partite systems, couplings
between subsystem. Adiabatic loops in the control $\cal M$ induce non trivial
unitary transformations on the computational space. For a generic system it is
shown that this mechanism allows for universal quantum computation by composing
a generic pair of loops in $\cal M.$
