## Quantum ComputersI attended the Caltech Seminar Day on 16th May 09 and heard a lecture: Quantum Information Science presented by Professor J Preskill. His lecture had a number of slides showing how the three dimensions of Quantum states function. He mentioned Quantum Computers as the next step in computer science from the classical transistor based digital computers which have made such a change in the life of modern day humans. Since I have a deep interest in computer science based on my professional experience: designing Avionics systems for military aircraft which were the first to use digital computers, Teaching Computer Science as an adjunct assistant professor to graduate students, Designing and fabricating small digital computers in a small company I decided I needed to learn about Quantum Computers and where research is going in this important new technology. The way I discovered the status of Quantum Computer is using the Google & Yahoo search engines. I was happy that Indiana University and Caltech have active Quantum Computer Research programs in progress. Jon Schiller holds a BS in Physics from Caltech and a PhD from the University of Southern California in EE & Mathematics. He has authored: 21st Century Cosmology |
