Quantum Computing for Technology Managers

on Comments (3)

Wiley’s Handbook of Technology Management, which includes my entry on Quantum Computing, just appeared. I received my tome in the mail today. It is definitely the biggest, weightiest, and most expensive publication I’ve contributed to yet! I was only willing to write the entry if I could also post it on the ArXiv. Wiley agreed, so you can find my entry on the ArXiv as “An Overview of Quantum Computing for Technology Managers.”

I hope the entry conveys the excitement of the field while eliminating some of the hype.  It is focused on what is known about what quantum computers can and cannot do. It does not try to explain how they do what they do. (For that, my tutorial with Wolfgang Polak remains a good starting place.) While the entry discusses well known aspects of quantum computation, such as Shor’s algorithm, quantum key distribution, and quantum teleportation,  it also discusses many lesser known results including more recent algorithmic results and established limitations on quantum computation. I had the pleasure of writing about some of my favorite topics in quantum computing, including purely classical results inspired by the quantum information processing point of view, the elegant cluster state model of quantum computation, and Aaronson’s suggestion that limits on computational power be considered a fundamental guiding principle for physical theories, much like the laws of thermodynamics.

Securing the identity of a past FXPAL researcher

on Comments (1)

Volker Roth left FXPAL last year to become a professor at Freie Universität Berlin. There he leads the Secure Identity Research Group, which takes a user centered approach to addressing security and privacy issues related to mobile devices, cloud computing, and the internet.

He and his group have gotten press recently due to a well-publicized celebration of the opening of their new building. There are some great photos of Volker at this opening on the  Bundesdruckerei web site (Bundesdruckerei endowed the position Volker filled and provides other support for the group).  On the same site is a picture of Volker hobnobbing with Horst Köhler, the president of Germany, and his wife! It is great to see Volker thriving.
