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

SUMMARY:Triangle Quantum Computing Seminar
DESCRIPTION:Join Today’s Duke\, NC State and UNC collaborative Triangle Quantum Computing Seminar \nTalk Title: Error mitigation and compiling \nSpeaker: Nathan Earnest-Noble \nHosted by:  IBM Quantum Hub at NC State \nAbstract:  Quantum Computing has fully emerged into a cloud enabled paradigm\, which is in a constant state of innovation.   A critical tool at the interface between quantum and classical consideration is the compiler – qubit mapping\, gate mapping\, pulse optimization and much more get lumped into this tool. A common consideration within these compilers is how to take the existing errors of noisy hardware and mitigate their impacts. In this talk I will review some recent experimental implementation of compilation methods which can be accessible to users\, each with an associated overhead and relative overall improvement. I will consider how these tools can work together to allow users to keep intricate control of a system while abstracting away the need to worry about some of the details when so desired. \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 Error Correction in Costa Rica \nSpeaker: Mauricio Gutierrez \nHosted by:  Duke Quantum Center \nAbstract:   Fault-tolerant (FT) quantum computers will rely on quantum error correcting codes to actively protect the logical information from the deleterious effects of noise. Therefore\, quantum error correction (QEC) will be a crucial part in the construction of quantum computers capable of outperforming their classical counterparts in important problems. In this talk I will review some of my past and current work on QEC\, including feasibility studies of small QEC codes on realistic quantum architectures and the use of machine-learning techniques to improve the decoding process. I will also briefly talk about our future plans regarding the study of error mitigation schemes for the variational quantum eigensolver\, a popular algorithm that could be very useful for quantum chemistry before the advent of FT quantum computers. \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:  Variational Quantum Boltzmann Machines \nSpeaker: Christa Zoufal\, IBM – Zurich \nHosted by:  IBM Quantum Hub at NC State \nAbstract:  This work presents a novel realization approach to Quantum Boltzmann Machines (QBMs). The preparation of the required Gibbs states\, as well as the evaluation of the loss function’s analytic gradient is based on Variational Quantum Imaginary Time Evolution\, a technique that is typically used for ground state computation. In contrast to existing methods\, this implementation facilitates near-term compatible QBM training with gradients of the actual loss function for arbitrary parameterized Hamiltonians which do not necessarily have to be fully-visible but may also include hidden units. The variational Gibbs state approximation is demonstrated with numerical simulations and experiments run on real quantum hardware provided by IBM Quantum. Furthermore\, we illustrate the application of this variational QBM approach to generative and discriminative learning tasks using numerical simulation. \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 field theories from quantum cellular automata \nSpeaker: Todd Brun\, USC Viterbi School of Engineering \nHosted by:  Duke Quantum Center \nAbstract:  Work done in collaboration with Leonard Mlodin \nQuantum walks (QWs) are unitary analogues of classical random walks\, and quantum cellular automata (QCAs) are unitary analogues of classical cellular automata. The QW on the 3D body-centered cubic lattice gives rise to solutions of the Dirac equation in the long-wavelength limit\, both in 1D and 3D; in 1D\, a two-dimensional internal space is required\, and in 3D a four-dimensional internal space. QWs can be treated as the one-particle sector of a QCA\, so it is natural to seek QCAs that give rise to quantum field theories in a similar limit.  This can be done fairly straightforwardly in one spatial dimension\, with the QCA being naturally described in terms of creation and annihilation operators that create or destroy particle locally\, evolve simply under the QCA unitary\, and obey the usual anticommutation relations.  However\, generalizing this construction to two or more spatial dimensions fails:  the requirements of anticommuting creation and annihilation operators are inconsistent with a local QCA.  For a QCA to give rise to a fermionic quantum field theory in the long-wavelength limit\, one must give up at least one desired property of the QCA. To evade this no-go theorem\, one can let the local subsystems become high-dimensional\, and restrict to the completely antisymmetric subspace of a larger space. Bosonic QCAs can also be constructed; these do not have the same problem with anticommutation\, but also require high-dimensional local subsystems. Taking these constructions as a model of particles propagating in discrete spacetime\, the discreteness could be detected using non-parallel matter interferometers. Finally\, we consider the problem of adding fermion-boson interactions\, and progress towards constructing a fully interacting QCA model\, and the potential for using QCAs to simulate quantum field theory. \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 Series
DESCRIPTION:Join Today’s Duke\, NC State and UNC’s collaborative Triangle Quantum Computing Seminar \nTalk Title: Faster and More Reliable Quantum SWAPs via Native Gates \nSpeaker:  Pranav Gokhale\, Co-founder and CEO of Super.tech \nHosted by:  Duke Quantum Center \nAbstract:  Due to the sparse connectivity of superconducting quantum computers\, qubit communication via SWAP gates accounts for the vast majority of overhead in quantum programs. We introduce a method for improving the speed and reliability of SWAPs at the level of the superconducting hardware’s native gateset. Our method relies on four techniques: 1) SWAP Orientation\, 2) Cross-Gate Pulse Cancellation\, 3) Commutation through Cross-Resonance\, and 4) Cross-Resonance Polarity. Importantly\, our Optimized SWAP is bootstrapped from the pre-calibrated gates\, and therefore incurs zero calibration overhead. We experimentally evaluate our optimizations with Qiskit Pulse on IBM hardware. Our Optimized SWAP is 11% faster and 13% more reliable than the Standard SWAP. We also experimentally validate our optimizations on application-level benchmarks. Due to (a) the multiplicatively compounding gains from improved SWAPs and (b) the frequency of SWAPs\, we observe typical improvements in success probability of 10-40%. The Optimized SWAP is available through the SuperstaQ platform. \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:Quantum Lunch Series Event - Speaker Yannick Meurice
DESCRIPTION:Talk Title: From Tensorial Formulations of Abelian Gauge Theories to Quantum Computing \nSpeaker: Yannick Meurice\, Professor with the Department of Physics and Astronomy at the University of Iowa. \nAbstract: We give a brief introduction to the physics goals of Tensor Field Theory (for a recent review see arXiv:2010.06539). We show that standard identities and theorems for lattice models with U(1) symmetry get re-expressed discretely in the tensorial formulation. \nWe construct a gauge-invariant transfer matrix in arbitrary dimensions. We show the equivalence with its gauge-fixed version in a maximal temporal gauge and explain how a discrete Gauss’s law is always enforced. We propose a noise-robust way to implement Gauss’s law in arbitrary dimensions. \nWe discuss applications for quantum computing and quantum simulation experiments \n  \nThis is a Virtual Event. \nIf you are interested in attending this event please email: \nquantumcomputing@ncsu.edu
