SUMMARY:Triangle Quantum Computing Seminar 
DESCRIPTION:Join Today’s Duke\, NC State and UNC collaborative Triangle Quantum Computing Seminar \nTalk Title: Generative Quantum Learning of Joint Probability Distribution Functions \nSpeaker: Elton Zhu \nHosted by:  IBM Quantum Hub at NC State \nAbstract:  Modeling joint probability distributions is an important task in a wide variety of fields. One popular technique for this employs a family of multivariate distributions with uniform marginals called copulas. While the theory of modeling joint distributions via copulas is well understood\, it gets practically challenging to accurately model real data with many variables. In this work\, we show that any copula can be naturally mapped to a multipartite maximally entangled state. Thus\, the task of learning joint probability distributions becomes the task of learning maximally entangled states. We prove that a variational ansatz we christen as a `qopula’ based on this insight leads to an exponential advantage over classical methods of learning some joint distributions. As an application\, we train a Quantum Generative Adversarial Network (QGAN) and a Quantum Circuit Born Machine (QCBM) using this variational ansatz to generate samples from joint distributions of two variables in historical data from the stock market. We demonstrate our generative learning algorithms on trapped ion quantum computers from IonQ for up to 8 qubits. Our experimental results show remarkable findings such as the resilience against noise\, outperformance against equivalent classical models and 20-1000 times less iterations required to converge as compared to equivalent classical models. \n  \nThis is a Hybrid Event with NC State. \nThe In Person location for NC State is Venture Place\, 2nd Floor\, Large Classroom. \nREGISTRATION: Form Link  \nFor more information email:  quantumcomputing@ncsu.edu

DESCRIPTION:Join Today’s Duke\, NC State and UNC collaborative Triangle Quantum Computing Seminar \nTalk Title: Quantum Algorithm for Stochastic Optimal Stopping Problems \nSpeaker: João Doriguello \nHosted by:  UNC Kenan-Flagler Rethinc. Labs \nAbstract:   The famous least squares Monte Carlo (LSM) algorithm combines linear least square regression with Monte Carlo simulation to approximately solve problems in stochastic optimal stopping theory. In this work\, we propose a quantum LSM based on quantum access to a stochastic process\, on quantum circuits for computing the optimal stopping times\, and on quantum Monte Carlo techniques. For this algorithm we elucidate the intricate interplay of function approximation and quantum Monte Carlo algorithms. Our algorithm achieves a nearly quadratic speedup in the runtime compared to the LSM algorithm under some mild assumptions. Specifically\, our quantum algorithm can be applied to American option pricing and we analyze a case study for the common situation of Brownian motion and geometric Brownian motion processes. \n  \nThis is a Hybrid Event with NC State. \nThe In Person location for NC State is Venture Place\, 2nd Floor\, Large Classroom. \nREGISTRATION: Form Link  \nFor more information email:  quantumcomputing@ncsu.edu

SUMMARY:Triangle Quantum Computing Seminar
DESCRIPTION:Join Today’s Duke\, NC State and UNC collaborative Triangle Quantum Computing Seminar \nTalk Title:  NISQ-HHL: Portfolio Optimization for Near-Term Quantum Hardware \nSpeaker: Dylan Herman \nHosted by:  UNC Kenan-Flagler Rethinc. Labs \nAbstract:  Portfolio optimization is an essential use case in Finance\, but its computational complexity forces financial institutions to resort to approximated solutions\, which are time consuming. Using the method of Lagrange multipliers\, the mean-variance portfolio optimization problem can be represented by a system of linear equations and potentially benefit from the exponential speedup provided by the HHL quantum algorithm. However\, multiple components in HHL are unsuitable for execution on Noisy Intermediate Scale Quantum (NISQ) hardware. This paper introduces NISQ-HHL\, the first hybrid formulation of HHL suitable for the end-to-end execution of small-scale portfolio-optimization problems on NISQ devices. NISQ-HHL extends the hybrid HHL variant with newly available quantum-hardware features: mid-circuit measurement\, qubit reset and reuse\, and Quantum Conditional Logic (QCL). To the best of our knowledge\, NISQ-HHL is the first algorithm incorporating a QCL-enhanced version of Phase Estimation executed on real hardware\, the trapped-ion Quantinuum System Model H1-1. In addition\, NISQ-HHL includes a novel method for choosing the optimal evolution time for Hamiltonian simulation. Although this paper focuses on portfolio optimization\, the techniques it proposes to make HHL more scalable are generally applicable to any problem that can be solved via HHL in the NISQ era. \n  \nThis is a Hybrid Event with NC State. \nThe In Person location for NC State is Venture Place\, 2nd Floor\, Large Classroom. \nREGISTRATION: Form Link  \nFor more information email:  quantumcomputing@ncsu.edu \n

SUMMARY:Triangle Quantum Computing Seminar - Last for Semester
DESCRIPTION:Join Today’s Duke\, NC State and UNC collaborative Triangle Quantum Computing Seminar \nTalk Title:  Computational Thinking Toward End-to-End Quantum Applications \nSpeaker: Xiaodi Wu \nHosted by:  IBM Quantum Hub at NC State \nAbstract: \n\n\n\nComputational Thinking is the thought process involved in formulating problems so that their solutions are represented in a form that can be effectively carried out by an information-processing agent. In this talk\, I will demonstrate how computational thinking can help us identify research opportunities where ideas from computer science could contribute to the implementation of end-to-end quantum applications. I will discuss projects guided by this principle in my group\, such as those on the design of programming languages and software toolchains for quantum computing\, and a proposal for scalable verification of quantum supremacy.\n\n\n\n  \nThis is a Hybrid Event with NC State. \nThe In Person location for NC State is Venture Place\, 2nd Floor\, Large Classroom. \nREGISTRATION: Form Link  \nFor more information email:  quantumcomputing@ncsu.edu
