Topic: Optimal Two-Qubit Circuits for Universal Fault-Tolerant Quantum Computation
Location: Zoom
QSEC’s quantum computing subgroup will organize and host a seminar series throughout the upcoming semester. The series will be kicked off on Tuesday September 15 with Mathematics Adjunct faculty Dr. Andrew Glaudell giving a short presentation. These events are free and open to the public. For any questions, contact qsec@gmu.edu. Below is the abstract of Dr. Glaudell’s talk and meeting information:
Abstract
We study two-qubit circuits over the Clifford+CS gate set which consists of Clifford gates together with the controlled-phase gate CS=diag(1,1,1,i). The Clifford+CS gate set is universal for quantum computation and its elements can be implemented fault-tolerantly in most error-correcting schemes with magic state distillation. However, since non-Clifford gates are typically more expensive to perform in a fault-tolerant manner, it is desirable to construct circuits that use few CS gates. In the present paper, we introduce an algorithm to construct optimal circuits for two-qubit Clifford+CS operators. Our algorithm inputs a Clifford+CS operator U and efficiently produces a Clifford+CS circuit for U using the least possible number of CS gates. Because our algorithm is deterministic, the circuit it associates to a Clifford+CS operator can be viewed as a normal form for the operator. We give a formal description of these normal forms as walks over certain graphs and use this description to derive an asymptotic lower bound of 5log(1/epsilon)+O(1) on the number CS gates required to epsilon-approximate any 4×4 unitary matrix.

Dr. Bill Phillips, Nobel Laureate,University of Maryland
Laurie Locascio, VP for Research; University of Maryland
Curious about the buzz around quantum, but don’t really understand what the big deal is? Want to understand how the quantum revolution applies to you but don’t have a background in physics?
If so, please join the Mid-Atlantic Quantum Alliance (MQA) for a fireside chat between University of Maryland’s Vice President for Research, Dr. Laurie Locascio, and Nobel Laureate Dr. Bill Phillips. Dr. Phillips is a renowned science communicator in addition to being a leading scientist, and currently serves as a NIST Fellow and a University of Maryland Distinguished University Professor. This fireside chat will include a discussion of Dr. Phillips’ Nobel journey, a basic introduction to quantum physics, and answers to burning questions about the promise of emerging quantum technologies.
This fireside chat will be the first in a series of MQA virtual events that will dive more deeply into the remarkable capabilities that advances in quantum are unlocking for computing, sensing and ultra-secure communications — and how these will help to address real-world challenges. This MQA introductory series will help to connect potential customers and end-users with the research community to accelerate the innovation of quantum products that are responsive to actual needs and deliver value.

Topic: Quantum Computing with Qiskit
QSEC’s quantum computing subgroup will organize and host a seminar series throughout the upcoming semester. The upcoming seminar on Tuesday September 29 with Mr. Ian Morris of GMU Department of Physics and Astronomy giving a short tutorial on Qiskit. These events are free and open to the public. For any questions, contact qsec@gmu.edu. Below is the abstract of Mr. Morris’s talk and meeting information:
Abstract
Curious about quantum computing but never had a chance to learn? Come to this hands-on tutorial and see quantum circuits in action!
Qiskit (qiss-kit) is an opensource Software Development Kit created by IBM that provides users access to real quantum computers to run their quantum circuits on. With Qiskit, users are able to execute their quantum circuit code on various quantum hardware architectures ranging from superconducting qubits to trapped ions, access a large set of premade circuits which can serve as benchmarks or building blocks for more complex circuits, and study the impact of noise on quantum circuits using built-in modules for noise characterization and optimization. In addition, Qiskit provides its users with a library of quantum algorithms from which users can draw on to research real world applications from machine learning to chemistry, as well as circuit tutorials, a free online textbook, YouTube explanations, and a blog featuring quantum applications that make learning how to use the SDK very simple. Qiskit’s easy to use interface enables users to start creating and implementing circuits immediately.

Title: Algorithmic Approaches to the MAX-CUT Problem
Abstract
In this talk, I am going to present three approximation algorithms to deal with the NP-hard problem MAX-CUT. The first one is a 0.5-approximation randomized algorithm, which can be de-randomized to be a deterministic one with the same performance. The second approximation algorithm is also a randomized algorithm and it has an approximation ratio 0.878. The third algorithm is a quantum approximation optimization algorithm (QAOA) with an approximation ratio 0.6942 on 3-regular graphs. In this talk, I will compare these algorithmic approaches. I will also discuss the inapproximability and some of my thoughts on solving MAX-CUT.
