    • qutip-qip: Pulse-level circuits simulation by Boxi Li

      About the talk

      In quantum computing, a quantum circuit is often represented as a sequence of unitary gates. However, when engineering quantum hardware, the physical qubits and their dynamics are usually described by the Hamiltonians. The characterization of noise also varies in those two different representations. Boxi will talk about quantum circuits represented by the control Hamiltonians and introduce the qutip-qip package, which represents and simulates quantum circuits at the pulse level. As a family package under the QuTiP organization, it leverages QuTiP's quantum dynamics solvers to solve the continuous time evolution of the qubits with realistic physical models. The package includes a few predefined physical models and provides the necessary compiling and scheduling functionality. In addition, it allows the user to build custom models of physical qubits and define various types of noise, such as environment-induced decoherence and noise in the control pulses.


      About the speaker

      Boxi Li is a PhD candidate at Forschungszentrum Jülich (Jülich research centre) in Germany, working on quantum control and modelling for superconducting qubits. I did my Bachelors at the University of Heidelberg and went to ETHZ for a master's degree, during which I also enjoyed a short stay at TU Delft, exploring the magic of quantum networks. I started my contribution to QuTiP from a GSoC project in 2019 and joined the development team thereafter, mainly maintaining the qutip-qip repository.


    • qrand: A multi-platform and multi-protocol quantum random number generator for arbitrary probability distributions by Pedro Rivero

      About the talk

      Random numbers are everywhere. Computer algorithms, data encryption, physical simulations, and even the arts use them all the time. There is one problem though: it turns out that they are actually very difficult to produce in large amounts. Luckily, the probabilistic nature of quantum computers makes these devices particularly useful for the task. QRAND introduces a versatile interface layer between NumPy and several quantum computing platforms (qiskit, cirq, qsharp...), along with some useful functionality that enables the production of quantum random numbers (QRN) according to different quantum protocols, and for a wide variety of probability distributions.

    • pyGSTi: A toolkit for quantum characterization by Erik Nielsen and Kenneth Rudinger

      Sample Jupyter notebooks from the talk

      About the talk

      In this talk, we will present pyGSTi, a python package for generating and analyzing quantum characterization, verification, and validation experiments, with particular focus on gate set tomography and scalable forms of randomized benchmarking. pyGSTi has been used to characterize and improve quantum hardware performance across a wide variety of platforms, including trapped ion, superconducting transmon, and silicon spin qubit devices. We will discuss the motivation behind pyGSTi, explore the functionality of and interplay between its basic objects, and provide several demonstrations of the code in action. These demonstrations will span a variety of examples, from high-level analyses which require minimal pyGSTi knowledge to more complex use cases which can fully leverage pyGSTi’s broad capabilities.


      About the speaker

      Erik and Kenneth both are researchers and developers working on pyGSTi at Sandia National Labs.

    • Intro to Pulser: Pulse simulation and design for neutral atoms by Loïc Henriet


      About the talk

      The manipulation of neutral atoms by light is at the heart of countless scientific discoveries in the field of quantum physics in the last three decades. The level of control that has been achieved at the single particle level within arrays of optical traps, while preserving the fundamental properties of quantum matter (coherence, entanglement, superposition), makes these technologies prime candidates to implement disruptive computation paradigms. In this talk, I will present pulser, a recently developed open-source python framework enabling practitioners to control those devices at the pulse level.


      About the speaker

      Loïc Henriet holds an engineering degree and a PhD in theoretical physics from Ecole Polytechnique, in France. He subsequently worked as a researcher at the Institute for Photonic Sciences (ICFO) in Barcelona, Spain. His research interests lied in the description of collective effects in light-matter systems. In June 2019, he joined Pasqal, a Paris-based quantum computing startup manufacturing quantum processors powered by arrays of single atoms. Since then, he has been heading the quantum software developments.

    • Intro to QuTiP: A Quantum Toolbox in Python by Shahnawaz Ahmed



      About the talk

      QuTiP: A quantum toolbox in Python, is one of the most popular tools to simulate open quantum systems – but it has expanded beyond that over the years. It is a simple but powerful library that, used by students, researchers, engineers, is having a tremendous impact on quantum science research. QuTiP is also Unitary Fund’s first affiliated project. In this talk, I will introduce the library and take the example of some new developments in QuTiP to show the ease with which one can simulate open quantum systems as well as contribute to the development of such open-source software tools to promote reproducibility and therefore accelerate the adoption of a particular simulation technique across the research community.

    • 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.


      About the speaker

      Alex McCaskey is a research scientist in the Computer Science and Mathematics Division at Oak Ridge National Laboratory. He serves as the Software Lead for the Quantum Computing Institute at ORNL and is the Project Lead for the XACC quantum framework and the QCOR quantum-classical C++ compiler. He received his Masters in Physics from Virginia Tech and BS degrees in Physics and Mathematics from the University of Tennessee.

    • 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.
