On Friday, November 14th, I attended the chemistry seminar that featured Dr. Kenneth Brown from Georgia Tech. The topic of his presentation was on ion trap quantum computers used for chemistry. These new quantum computers are currently in development and their production has been made possible due to breakthroughs in Dr. Brown's research of quantum computing in science.
During Dr. Brown's presentation, he touched based on the history of ion trapping. He informed us about Linus Pauling who was a revolutionary in the rules of chemistry. He deduced that H-F bonds are both covalent and ionic. Dr. Brown then went on to explain how this is possible and how it relates to quantum computing. The natural number, semiprime, who's equation is N=PQ was then introduced and it was explained how quantum computers allow for this equation to be solved much easier.
The next topic Dr. Brown covered was ion trapping. Ion trapping involves a surface electrode trap and has two major systems. Firstly, ions are trapped in an oscillating quadruple field. Secondly, ion stability is based on charge to mass ratio.

Dr. Brown then introduced a series of information that I was unfamiliar with. This included quantum computer requirements and improving the reliability of quantum computers. Quantum computers have 3 requirements: quantum bits/qubits, one qubit gates, and two qubit gates. Dr. Brown's research in improving quantum computing reliability includes better software and better hardware. Better software involves tasks such as improving algorithms and better hardware involves tasks such as improving thermodynamic and kinetic protection.

Lastly, Dr. Brown discussed him and his research team's major accomplishments. One individual on his team was actually involved in the creation of atomic clocks. Atomic clocks are based on the gravity on earth and it was explained that the bigger the gravitation pull, the faster time moves. I then learned about how a team of scientists were able to slow time within a controlled laboratory setting by which they were able to decrease gravitational pull at that location. Finally, I learned about Dr. Brown's work in ground state cooling, which he used to create the coldest molecular ion in history.
We had some of the same points in our summaries of this very interesting presentation!
ReplyDeleteI heard another of Dr. Brown's lectures, on the same topic, and it was really interesting for me. The talk was very interesting, and I think that it is interesting to see the future of computing!
