@article{146246, author = {Andrew A. Houck and Hakan E. T{\"u}reci and Jens Koch}, title = {On-chip quantum simulation with superconducting circuits}, abstract = { Using a well-controlled quantum system to simulate complex quantum matter is an idea that has been around for 30 years and put into practice in systems of ultracold atoms for more than a decade. Much recent excitement has focused on a new implementation of quantum simulators using superconducting circuits, where conventional microchip fabrication can be used to take design concepts to experimental reality, quickly and flexibly. Because the quantum {\textquoteright}particles{\textquoteright} in these simulators are circuit excitations rather than physical particles subject to conservation laws, superconducting simulators provide a complement to ultracold atoms by naturally accessing non-equilibrium physics. Here, we review the recent wealth of theoretical explorations and experimental prospects of realizing these new devices. {\textcopyright} 2012 Macmillan Publishers Limited.
