AB  - We discuss how leveraging Field Programmable Gate Array (FPGA) technology as part 
      of a high performance computing platform reduces latency to meet the demanding 
      real time constraints of a quantum optics simulation. Implementations of 
      complex-valued operations using fixed point numeric on a Virtex-5 FPGA compare 
      favorably to more conventional solutions on a central processing unit. Our 
      investigation explores the performance of multiple fixed point options along with 
      a traditional 64 bits floating point version. With this information, the lowest 
      execution times can be estimated. Relative error is examined to ensure simulation 
      accuracy is maintained.
