Christina Knapp, Gavin Brennen, and Rovin Blume-Kohout, each raised in Alaska, explain Quantum Information Science and their research challenges.  What is quantum information science? ·  At low temperatures and small system sizes, nature acts very differently than our everyday life would indicate. For instance, particles can act probabilistically with their behavior changing dramatically if they are being observed.  ·  Furthermore, particles can be highly correlated with each other so that a measurement of one particle can instantaneously affect a different particle far away. · The field of quantum information science seeks to understand how these properties can be used to create new technologies, such as quantum computers or secure communication. ·  This subject is of broad interest to academic groups, government agencies, and the technology industry, and spans the fields of physics, mathematics, computer science, and engineering.Christina Knapp was born and raised in Anchorage, and graduated from East High School in 2009.  She then went to Williams College in Massachusetts, where she planned to study English or history, but switched to physics and math after being introduced to the strange and wonderful world of quantum physics.  She finished her PhD in physics in June at the University of California, Santa Barbara, and will move to Caltech in the fall for a postdoc.  Her research focuses on how to use exotic phases of matter to build a quantum computer that is resilient to noise.  Much of her work is done in collaboration with Microsoft Station Q, a Microsoft research group dedicated to building what is known as a topological quantum computer.  Gavin Brennen grew up in Fairbanks, Alaska and graduated from UAF with a degree in physics. He went on to complete a PhD in quantum information at the University of New Mexico with a thesis proposing one of the first quantum computer architectures in what is known as an optical lattice. Afterward he worked as a post-doc at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland and a senior scientist position at the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck Austria. In 2007, Gavin moved to Macquarie University, Sydney Australia where he is currently a Professor of Physics and director of the Centre for Quantum Engineering. His interests range from how to build quantum computers and quantum enhanced sensors, to simulations of quantum field theory and quantum security for cryptocurrencies.  Robin Blume-Kohout was born on a kitchen table in the Bush, about 25 miles north of the village of Tanana.  After graduating from Fairbanks’s Lathrop H.S. in 1994, he went to Kenyon College in Ohio, where he majored in physics and English, swam competitively, and graduated in 1998.  He earned a Ph.D. in physics from UC-Berkeley in 2005 for research at Los Alamos National Lab on how decoherence lets classical reality emerge from quantum physics.  After postdoctoral fellowships at Caltech, the Perimeter Institute, and Los Alamos (again), he joined Sandia National Labs (Albuquerque, NM) as a staff scientist.  Today, Robin is the principal investigator for Sandia’s Quantum Performance Laboratory and an associate research professor at the University of New Mexico.  He tries to measure how well quantum computers work, and why they fail.  He lives in upstate New York with his wife and daughter, commutes a really long way to work, and tries to get back to his cabin in the Bush at least once a year to saw boards and fix the roof.

Building Quantum Computers with Christina Knapp, Gavin Brennen, Robin Blume-Kohout

With the advent of mature quantum technologies, many of the critical cryptographic protocols which secure the Internet, financial transactions and even military secrets may become susceptible to new attack vectors. For instance, while it may take a computer millions of years to decipher a public key’s corresponding private key, a sufficiently powerful quantum computer might achieve this in a reasonable amount of time. With this reality looming over us, many in the blockchain space worry that someone with access to a quantum computer might one day have the ability to steal their hard-earned crypto. We’re joined by Ajay Prakash and Gavin Brennen, founders of the Qubit Protocol, a decentralized blockchain-enabled governance protocol that is meant to select and fund the best startups in the quantum world. As a co-author of the recent paper “Quantum attacks on Bitcoin, and how to protect against them,” Gavin walks us through the primary threats that quantum computing poses on Bitcoin. Among the major vulnerabilities are hashing functions and Elliptic Curve algorithms used for digital signatures, both fundamental components of Bitcoin, as well as many other blockchain protocols. Topics covered in this episode:  What are quantum technologies and how they differ from the existing paradigm The areas and industries which are to benefit most from quantum computing A refresher on hashing algorithms as one-way functions What a quantum attack on Bitcoin mining might look like How Elliptic Curve digital signature algorithms work and how public and private keys are generated The three types of attacks a quantum computer could perform digital signatures The expected timelines for these attacks to be viable The potential countermeasures which could circumvent quantum attacks on Bitcoin The Qubit Protocol as a DAO to fund quantum technology startups and the challenges of investing in the quantum space The project’s roadmap and upcoming ICO  Episode links:  Qubit Protocol Quantum attacks on Bitcoin, and how to protect against them Quantum Computers Pose Imminent Threat to Bitcoin Security - MIT Technology Review" Shor's algorithm - Wikipedia Elliptic-curve cryptography - Wikipedia  This episode is hosted by Sébastien Couture.
