D-Wave Systems Inc. builds annealing devices that exhibit quantum effects. These devices as well as other physical systems implement a programmable Ising model of the form.
\begin{equation}
H = \sum_i c_i Z_i+\sum_{ ij} c_{ij}Z_iZ_j
\end{equation} […]
We developed quantum computer algorithms which utilize quantum effects to
In our work, we have taken part in several experimental collaborations which have realized prototypes of our algorithms.
In his famous 1981 talk, Feynman proposed that unlike classical computers, which would presumably experience an exponential slowdown when simulating quantum phenomena, a universal quantum simulator would not. An ideal quantum simulator would be controllable, and built using existing technology. […]
Tensor networks gave rise to efficiently compact representations for certain classes of quantum states, and provide a graphical language to reason about quantum processes.
The methods reach outside of physics to large areas of computer science and even more recently have found applications in complex networks. […]
