Final project presentations, session 2 ====================================== #. Fanny C #. Athreya M & Alejandro N T & Misha S #. Pavankumar R V #. Matthew Y & Justin M H & Lauren T Quantum computing at RPI ======================== RPI's Quantum Blueprint group would like to know: what would you like to see, in courses and research? #. a lower level course? #. fewer prereqs in this course? #. a minor? #. different topics in this course? I email you about the focus group session, this Wed at 4. Please try to attend; this will help to strengthen quantum computing at RPI. I will not be present; so you can be frank. Quantum physics explains USB behavior ===================================== .. image:: /files/quantum_usb_behavior.png Course material =============== Feynman ------- #. Feynman was the first to propose the theoretical idea of a quantum computer. `Richard Feynman - Quantum Mechanics `_ 4:01. Extracted from `HD Feynman: FUN TO IMAGINE complete 1080p `_ 1:06:49.

Disentangling hype from reality: Achieving practical quantum advantage https://www.youtube.com/watch?v=ybmKJBTXudk (14:28) Mar 26, 2021 Join distinguished Microsoft Scientist Matthias Troyer in his session on achieving practical quantum advantage from the 2020 Q2B event. List of algorithms ------------------ https://quantumalgorithmzoo.org/ Nasty probability distributions and failures in financial modeling ------------------------------------------------------------------ #. This expands my comments a few classes ago. #. Consider the **Cauchy** probability distribution. a. It's smooth and unimodal. #. It can happen in real experiments like spinning a pointer. #. However it has no moments. The integral to compute the mean diverges. #. The law of large numbers fails here. #. No paramatric sampling techniques are valid. #. See wikipedia. #. Generally, fat-tailed distributions have this problem; see wikipedia. #. There are good arguments that stock market numbers might be like this/ #. So, all the usual market analysis tools are invalid. #. This might be the math behind black swans, i.e., unusual events that happen more often than the models predict. #. Deleting extreme outlying observations might shrink the tails enough that the moments now are finite. However it's hard to put a formal foundation on this. #. Another problem with the models is that they can fail when you need them most. a. Their job is to compute prices, at which people will both buy and sell. #. In a panic, no one is buying; the market can break down. #. Read https://en.wikipedia.org/wiki/Long-Term_Capital_Management where models developed by 2 Nobel Econ winners failed and nearly caused a major financial market crash. To stop that, the Fed had to bail it out. #. Quantum computing will allow all this to happen faster.
