We Belong Together, Adiabatically

A paper dance today! Yes, indeed, it’s another slow dance (scirate, arXiv:0912.2098):

Adiabatic Cluster State Quantum Computing
Authors: Dave Bacon, Steven T. Flammia

Abstract: Models of quantum computation are important because they change the physical requirements for achieving universal quantum computation (QC). For example, one-way QC requires the preparation of an entangled “cluster” state followed by adaptive measurement on this state, a set of requirements which is different from the standard quantum circuit model. Here we introduce a model based on one-way QC but without measurements (except for the final readout), instead using adiabatic deformation of a Hamiltonian whose initial ground state is the cluster state. This opens the possibility to use the copious results from one-way QC to build more feasible adiabatic schemes.

    So… do you want us to try to build this thing? What would you do with it (ie if you had to pick a specific algorithm to run what would you pick)?

    Like all theorists, of course I want to build it! ..but sadly I will probably just stand by as experimentalists ignore me :(
