Robert Smith explains how Rigetti Computing uses Common Lisp to build quantum programming languages, compilers, and high-performance simulators.

Bay Area Lisp and Scheme Meetup balisp.org/ Thu 30 Nov 2017 Rigetti Computing Berkeley, CA Abstract Since the 1950s, Lisp has been used to describe and calculate in cutting-edge fields like artificial intelligence, robotics, symbolic mathematics, and advanced optimizing compilers. It is no surprise that Lisp has also found relevance in quantum computation, both in academia and industry. Hosted at Rigetti Computing, a quantum computing startup in Berkeley, Robert Smith will provide a pragmatic view of the technical, sociological, and psychological aspects of working with an interdisciplinary team, writing Lisp, to build the next generation of technology resource: the quantum computer. ABOUT THE SPEAKER: Robert has been using Lisp for over decade, and has been fortunate to work with and manage expert teams of Lisp programmers to build embedded fingerprint analysis systems, machine learning-based product recommendation software, metamaterial phased-array antennas, discrete differential geometric computer graphics software, and now quantum computers. As Director of Software Engineering, Robert is responsible for building the publicly available Rigetti Forest platform, powered by both a real quantum computer and one of the fastest single-node quantum computer simulators in the world. Video notes I apologize for the poor audio quality. It improves once Robert Smith begins speaking, when we switch to the lapel microphone, but it's still not ideal. In particular, I didn't check that the audio had two channels. That can't be fixed after uploading without changing the URL.

What people say. Shared as a great real-world example of using Common Lisp for cutting-edge systems like quantum computing compilers and simulators.

Interesting in this regard might also be the talk that Robert Smith of Rigetti Computing recently gave: link to this video Apart from praising Common Lisp he describes how they are building an assembler-like language for quantum computing. The HN thread: link

Rigetti Quantum Computing 0 is a YC startup that actually manufactures real quantum computers that are accessible through Forest. There are a couple neat videos about the tech. 1,2 You can access the service through a Python API 3.

On “What Made Lisp Different (2002)”

Rigetti Quantum Computing is a relatively recent YC startup that happens to use Common Lisp for building out their quantum programming language, compiler, and simulator stack. For those tasks, it has been an excellent choice, especially given the hugely exploratory and rapidly evolving space. Rigetti hosted one of the Lisp meetups to talk about their use of Lisp and it was recorded in a talk "Lisp at the Frontier of Computation" 0. 0 link to this video (Disclaimer: I'm the speaker in the video.)

On “Ask HN: Who is using Common Lisp?”

Rigetti Computing 1 uses it for a variety of their projects, including their high-performance quantum computer simulator called the QVM 2, and their quantum compiler. Some of their use of Lisp has been presented in more detail at the European Lisp Symposium. You can see it in the Cutting Edge section of the proceedings 3. 1 link 2 link to this video 3 link
