Agency / Branch: DOD / DARPA
Contract: W31P4Q-09-C-0349
Award Amount: $749,923.00


Quantum computing experiments use pulse programmers to generate programmable sequences of radio frequency pulses to perform quantum logic operations and error corrections. Currently pulse programmers are often designed in-house by individual quantum computing research groups. Consequently, they have only a small number of radio frequency channels and have a limited frequency range (up to 100 - 400 MHz) that falls far short of supporting solid-state qubit research. In Phase I of this program we have developed a new pulse programmer architecture that can support both trapped ion and solid-state qubit research by taking advantage of recent innovations in wireless communications and high-performance computing industries. The major features of the architecture are: (1) extensibility to hundreds of radio frequency and arbitrary waveform channels, (2) system-wide sub-picosecond clock synchronization, (3) direct digital synthesis beyond 400 MHz with phase coherent switching, (4) cost effective radio frequency synthesizer modules up to 22 GHz, (5) high-speed (1 GS/sec) pulse envelope generation, (6) ultra-fast (1 GBytes/sec) data link for fast waveform downloading, and (7) real-time feedback and dynamic pulse sequence execution for quantum error correction. This proposal describes the design of the pulse programmer, plans to build the prototype, and demonstrate its capabilities in a real quantum computing laboratory, and strategies to apply the technology to scientific, commercial and government markets.
