Quantum mechanics presents a more general and potentially more powerful model of computation than classical systems. Quantum bits have many physically different representations which nonetheless share a common need for modulating pulses of electromagnetic waves. This thesis presents the design and evaluates the implementation of a general-purpose sequencer which supports fast, programmable pulses; a flexible, open design; and feedback operation for adaptive algorithms. The sequencer achieves a timing resolution, minimum pulse duration, and minimum delay of 10 nanoseconds; it has 64 simultaneously-switching, independent digital outputs and 8 digital inputs for triggering or feedback. Multiple devices can operate in a daisy chain to facilitate adding and removing channels. An FPGA is used to implement a firmware network stack and a specialized pulse processor core whose modules are all interconnected using the Wishbone bus standard. Users can write pulse programs in an assembly language and control the device from a host computer over an Ethernet network. An embedded web server provides an intuitive, graphical user interface, while a non-interactive, efficient UDP protocol provides programmatic access to third-party software. The performance characteristics, tolerances, and cost of the device are measured and compared with those of contemporary research and commercial offerings. Future improvements and extensions are suggested. All circuit schematics, PCB layouts, source code, and design documents are released under an open source license.
