Negative Group Delay
NGD. Quantumbit has been developing "negative group delay" technology since 2005. See Chiao #1 & Chiao #2 for good background on the subject. The Company originally introduced the subject of negative group delay to Malcolm Skolnick, PhD (physics), Chris Hymel, Ron Stubbers (electrical engineers) and contracted Hymel & Stubbers through Signal Advance, Inc. (f.k.a., Biodyne Development, Inc.) to develop the technology for Quantumbit. Quantumbit has constructed negative group delay circuits and successfully sent bits backwards in time by roughly one second. The next generation negative group delay devices will be embodied in digital signal processors. The time advance (i.e., negative delay) and data rate should be useable for practical applications. The applications are far reaching, from delay free communications to precisely forecasting markets, weather, news or other information.
After his work with Quantumbit, Chris Hymel wrote a thesis regarding applications of negative group delay and its applications in biomedical engineering earning him a PhD in that field. Chris Hymel, PhD, Malcolm Skolnick, PhD, and Karl Zercoe, all former Directors of Quantumbit, and Ron Stubbers, continue to pursue negative group delay applications through Signal Advance, Inc. and recently authored the feature article in the Third Quarter 2011 IEEE Circuits and Systems Magazine, "Temporally Advanced Signal Detection". Signal Advance, Inc. won First Place in the 2011 Goradia Innovation Prize for its work with the technology.
