Abstract

Recent work has demonstrated the feasibility of using an array of quantum information processors connected via classical channels (type II quantum computer) to implement a quantum lattice-gas algorithm. This paper describes work towards constructing a new experimental set-up for a type II quantum computer. This set-up has new hardware and software specifications but does follow previously published approaches of operation encoding the initial mass density onto a twoqubit processor and using standard pulse techniques to step through the algorithm. New hardware for this system includes the ability to read both qubits at once, effectively reducing the processing time by twofold. Hardware changes also include the use of multiple coils controlled by a single spectrometer and a hardware switch. New software includes a top level control system for the spectrometer for quick experimental configuration as well as configurable modeling software to verify results. Results are presented here from a system with the final software implementations and the two channel spectrometer configuration run on a single prototype coil. Progress towards the final multi-coil implementation is described.
