Intro to qcor: Extending C++ for Heterogeneous Quantum-Classical Computing by Alex McCaskey
About the talk
We present qcor - a language extension to C++ and compiler implementation that enables heterogeneous quantum-classical programming, compilation, and execution in a single-source context. Our work provides a first-of-its-kind C++ compiler enabling high-level quantum kernel (function) expression in a quantum-language agnostic manner, as well as a hardware-agnostic, retargetable compiler workflow targeting a number of physical and virtual quantum computing backends. qcor leverages novel Clang plugin interfaces and builds upon the XACC system-level quantum programming framework to provide a state-of-the-art integration mechanism for quantum-classical compilation that leverages the best from the community at-large. qcor translates quantum kernels ultimately to the XACC intermediate representation, and provides user-extensible hooks for quantum compilation routines like circuit optimization, analysis, and placement. This work details the overall architecture and compiler workflow for qcor, and provides a number of illuminating programming examples demonstrating its utility for near-term variational tasks, quantum algorithm expression, and feed-forward error correction schemes.

Intro to qrack: a framework for fast quantum simulation by Daniel Strano
About the talk
vm6502q/qrack is a quantum computer simulation framework designed for the highest performance on the widest possible range of consumer-grade "classical" hardware platforms. It has 0 required external software dependencies besides C++11 standard, it optionally supports OpenCL accelerators back to the v1.1 standard, including multi-accelerator operation, and it prides itself on its "novel optimization layer." The speaker will outline the many features of the framework, including the theory behind the novel optimization layer, culminating in a simulator stack whose general use case is also its highest performance "Swiss Army knife" simulator, which has been integrated with a much wider developing quantum open source stack via plugins. Quantitative benchmarks will also be discussed, including performance on the quantum Fourier transform and an example of a "quantum volume"-type random universal circuit.

About the speaker
Daniel Strano is senior software developer for PDHI (Basking Ridge, NJ). He holds a B.A. in physics and has worked as a data scientist or software engineer for companies including Pacific Northwest National Laboratories (Richland, WA) and S&A Technologies, LLC (Newark, NJ). For the past three years, he is the lead developer of the vm6502q/qrack quantum computing simulation framework, along with Benn Bollay, which has received a Unitary Fund grant. His personal research and literary blog is at ultraphrenia.com, including information and videos about his open source extensions to the OpenRelativity physics module for Unity3D, by the MIT Game Lab, to which he is a community contributor via a personal fork on GitHub.
