Realization of quantum process tomography in NMR
Andrew M. Childs, Isaac L. Chuang, Debbie W. Leung
Quantum process tomography is a procedure by which the unknown dynamical evolution of an open quantum system can be fully experimentally characterized. We demonstrate explicitly ho…
Universal quantum computation with two-level trapped ions
Andrew M. Childs, Isaac L. Chuang
Although the initial proposal for ion trap quantum computation made use of an auxiliary internal level to perform logic between ions, this resource is not necessary in principle. I…
Universal simulation of Markovian quantum dynamics
Dave Bacon, Andrew M. Childs, Isaac L. Chuang +3
Although the conditions for performing arbitrary unitary operations to simulate the dynamics of a closed quantum system are well understood, the same is not true of the more genera…
Exact sampling from non-attractive distributions using summary states
Andrew M. Childs, Ryan B. Patterson, David J. C. MacKay
Propp and Wilson's method of coupling from the past allows one to efficiently generate exact samples from attractive statistical distributions (e.g., the ferromagnetic Ising model)…
