Talk Title: The quest to quantum advantage – state of play<\/strong><\/h2>\n <\/summary>\n

\n \n\n

Achieving quantum advantage within the next two years is a milestone that will only be possible through close collaboration between the quantum compute resources and high-performance computing (HPC) \u2014especially given the substantial resource demands of scaling quantum circuits beyond the 100-qubit regime. Now that we\u2019ve entered the era of quantum utility, marked by quantum systems capable of outperforming classical simulators in meaningful tasks, the path to reliable quantum advantage requires continued innovation across hardware, software, and algorithm design.<\/p>\n\n\n\n

In this talk, I will highlight recent progress along the IBM Quantum development roadmap, including advances in utility-scale processors, quantum-centric supercomputing, and the Qiskit software stack. I will take a deeper look at Sample-based Quantum Diagonalization (SQD) and its variants, which not only demonstrate the growing capabilities of quantum systems but also underscore the essential role of HPC in realizing scalable, noise-resilient quantum algorithms.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n

Talk Title: Quantum hardware-enabled molecular dynamics via transfer learning<\/strong><\/h2>\n <\/summary>\n

\n \n\n

The ability to perform ab initio molecular dynamics simulations using potential energies calculated on quantum computers would allow virtually exact dynamics for chemical and biochemical systems, with substantial impacts on the fields of catalysis and biophysics. However, noisy hardware, the costs of computing gradients, and the number of qubits required to simulate large systems present major challenges to realizing the potential of dynamical simulations using quantum hardware. Here, we demonstrate that some of these issues can be mitigated by recent advances in machine learning. By combining transfer learning with techniques for building machine-learned potential energy surfaces, we propose a new path forward for molecular dynamics simulations on quantum hardware.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n

Quantum Advantages Across Eight Use Cases<\/strong><\/h2>\n <\/summary>\n

\n \n\n

This presentation showcases eight practical quantum AI computing
applications developed at Savannah River National Laboratory (SRNL),
demonstrating real quantum advantages in diverse problem domains. All
implementations represent working code rather than theoretical
frameworks, emphasizing the practical readiness of quantum-enhanced
solutions, thereby putting science to work.<\/p>\n\n\n\n

Strongly correlated biomolecular systems such metalloproteins are critical to understanding the important cellular functioning and the pathogenesis of neurodegenerative diseases. Examples include iron-sulfur clusters, believed to be responsible for correct cellular functioning, as well as the amyloid-beta protein aggregating via metal ions such as zinc, iron, or copper and leading to dysfunction. The mechanisms of coordination, dynamics, and other physiological factors in these metalloproteins aren\u2019t fully understood.

Talk Title: Quantum-Accelerated Optimal Meter Placement in Energy Systems<\/h2>\n <\/summary>\n

\n \n\n

Meter infrastructure is critical for real\u2011time monitoring and control of complex engineering systems, particularly modern power grids, but optimally locating meters is an NP\u2011hard combinatorial problem that becomes computationally prohibitive as network size and renewable integration grow. In this talk, a hybrid quantum\u2011classical method based on the Quantum Approximate Optimization Algorithm (QAOA) is presented to tackle meter placement under both unconstrained and channel\u2011limited scenarios. To analyze the QAOA-generated solution distributions, recursion-based Depth-First Search and Breadth-First Search algorithms are developed, which reduces the complexity from quadratic to linear time. Additionally, quantum parameter studies are conducted to identify key factors influencing QAOA performance and provide insights into tuning these critical parameters. Benchmarks on standard IEEE systems demonstrate better placement and faster runtimes than leading classical methods, paving the way for improved quantum\u2011enhanced grid monitoring in the Noisy Intermediate Scale Quantum era.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n

Talk Title: Sample-Based Quantum Bootstrap Embedding<\/h2>\n <\/summary>\n

\n \n\n

One problem where quantum computers are hoped to demonstrate an advantage in the near term is the electronic structure problem in quantum chemistry, where one attempts to find the ground state energy of a molecular system. In recent years, quantum computers have scaled up to hundreds of physical qubits. Simultaneously, the development of sample-based diagonalization methods in recent years has brought down the runtime of simulating such systems drastically as compared to the variational quantum eigensolver. The combination of these developments has opened up an opportunity to begin to explore system sizes that are intractable to both classical diagonalization and quantum variational methods. In this work we combine sample-based diagonalization with quantum bootstrap embedding, a method wherein one breaks a molecule into non-disjoint fragments and solves for the energy self-consistently by matching the reduced density matrices of neighboring fragments on their overlapping regions. Furthermore, we show that the sample-based diagonalization approach can be used to reconstruct the global wavefunction of the system from its constituent fragment wavefunctions.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n

Talk Title: Parametric Circuit Synthesis and Bosonic VQAs<\/h2>\n <\/summary>\n

\n \n\n

Variational quantum algorithms (VQAs) are a promising approach to solve relevant quantum chemistry and optimization problems algorithmically. However, making use of these approaches takes two-fold knowledge: the problem to be solved, and the quantum technology to be used. Our NchooseK programming model allows users to focus on only the variable relationships of their problem and automatically maps the problem appropriately to a user selected solver. Building on our past work, we contribute two novel solution approaches. The first synthesizes approximate circuits for the ansatz of the VQA to closely approximate the original circuit in such a way that on-line compilation is not necessary at every iteration of the VQA. These approximate circuits can be used both in simulation and on hardware and yield solutions of comparable fidelity to the baseline in both simulation and hardware experiments while reducing the average number of CNOTs required by 32\\%. The second is in-progress work to add an additional solver to the framework to leverage qumode (bosonic) devices rather than exclusively qubit based ones. This approach has the potential to provide superior solution fidelity due to richer bosonic encodings. We leverage bosonic-qisikit to create and compare hybrid (qumode-qubit) VQA circuits with native gate representations. We intend to use this as a comprehensive comparison between qubit- and qumode-based devices as well as begin to consider various potential native qumode-based gate mixers for QAOA.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n

Talk Title: When Memory Fails, Quantum Discord Remembers<\/h2>\n <\/summary>\n

\n \n\n

In classical game theory, Kuhn\u2019s Theorem shows that in games with perfect recall, behavioral and mixed strategies are equivalent. But this equivalence breaks down when recall is imperfect \u2014 behavioral strategies lose their coordination power. In this talk, I present a quantum analogue to Kuhn\u2019s result. I show that a behavioral-style quantum strategy, using only local measurements on a separable (non-entangled) quantum state with nonzero discord, can replicate the performance of a classical mixed strategy in an imperfect recall game. This coordination is impossible with classical memoryless strategies. The result highlights quantum discord\u2014not entanglement\u2014as a minimal and robust resource for restoring strategic coordination without memory, suggesting new directions for modeling bounded rationality in quantum systems.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n

In the NISQ era, quantum error mitigation (QEM) is essential for producing reliable outputs from quantum circuits. We present a statistical signal processing approach to QEM that estimates the most likely noiseless outputs from noisy measurements. The noiseless outputs are estimated by optimizing over a probabilistic noise formulation. We demonstrate the effectiveness of this approach using simulated data and IBM QPU data, and compare its performance to state-of-the-art statistical QEM techniques, showing significant improvement in fidelity.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n

Talk Title: QuESat: Satellite-Assisted Quantum Internet for Global-Scale Entanglement Distribution<\/h2>\n <\/summary>\n

\n \n\n

Entanglement distribution across remote distances is critical for many quantum applications. Currently, the de facto approach for remote entanglement distribution relies on optical fiber for on-the-ground entanglement distribution. However, the fiber-based approach is incapable of global-scale entanglement distribution due to intrinsic limitations. This paper investigates a new hybrid ground-satellite quantum network architecture (QuESat) for global-scale entanglement distribution, integrating an on-the-ground fiber network with a global-scale passive optical network built with low-Earth-orbit satellites. The satellite network provides dynamic construction of photon lightpaths based on near-vacuum beam guides constructed via adjustable arrays of lenses, forwarding photons from one ground station to another with very high efficiency over long distances compared to using fiber. To assess the feasibility and effectiveness of QuESat for global communication, we formulate lightpath provisioning and entanglement distribution problems, considering the orbital dynamics of satellites and the time-varying entanglement demands from ground users. A two-stage algorithm is developed to dynamically configure the beam guides and distribute entanglements, respectively. The algorithm combines randomized and deterministic rounding for lightpath provisioning to enable global connectivity, with optimal entanglement swapping for distributing entanglements to meet users’ demands. By developing a ground-satellite quantum network simulator, QuESat achieves multi-fold improvements compared to repeater networks.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n

Talk Title: High Temperature Quantum Coherence in Solids<\/h2>\n <\/summary>\n

\n \n\n

The formation of coherent macroscopic states and the manipulation of their entanglement using external stimuli are essential for emerging quantum applications. However, the observation of collective quantum phenomena such as Bose\u2013Einstein condensation, superconductivity, superfluidity and superradiance has been limited to extremely low temperatures to suppress dephasing due to random thermal agitations. In this presentation I will talk about room-temperature superfluorescence (SF) in hybrid perovskite thin films. In SF an optically excited population of incoherent dipoles develops collective coherence spontaneously. This emergent collective state forms a giant dipole and radiates a burst of photons. The discovery of room temperature SF in perovskites is very surprising and shows that in this material platform, there exists an extremely strong immunity to thermal dephasing. To explain this observation, I will introduce the quantum analogue of vibration isolation (QAVI) mechanism, which protects electronic excitations against dephasing even at room temperature. Understanding the origins of sustained quantum coherence at high temperatures can provide guidance to design systems for emerging quantum information technologies and to realize similar high-temperature macroscopic quantum phenomena in tailored materials.

Talk Title: Chiral Quantum State Transfer in Non-Hermitian Dynamics<\/h2>\n <\/summary>\n

\n \n\n

Open systems with loss or gain, described by effective non-Hermitian Hamiltonians, have attracted significant attention in the last two decades. These systems generally possess complex eigenvalues and nonorthogonal eigenstates. Their degeneracies are known as exceptional points (EPs), where both the eigenvalues and the corresponding eigenstates become degenerate. This peculiar behavior has led to many nonintuitive phenomena and applications in classical platforms, including EP sensors and chiral state transfer via encircling an EP. Recently, there has been growing interest in harnessing non-Hermitian dynamics and EPs for quantum applications. Open quantum systems provide a natural platform for exploring the relevant physics. In this talk, I will discuss chiral state transfer via dynamically encircling an EP in a circuit QED setup and the approach to mitigate the decoherence effect. I will also introduce a Floquet picture to interpret the observations, which offers a way to engineer quantum dissipators. Finally, I will discuss a theoretical proposal leveraging the same idea for generating Bell states in a dissipative two-qubit system.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n

Talk Title: Optimization of Circular Bragg Gratings via Guided Mode Expansion Method-Based Inverse Design<\/h2>\n <\/summary>\n

\n \n\n

Spin-photon interfaces established by coupling between optically-active spin systems and photonic cavities with high cooperativity are vital for quantum information processing. Specifically, \u201cBullseye\u201d cavities formed by periodic etching of rings offer an optically accessible spin-photon interface but lack the high cooperativity required for quantum applications due to the low quality factor of the cavities (<1000). Here, we use differentiable guided-mode expansion (GME) inverse-design method to design novel cavities with quality factors as high as ~1000 while maintaining the efficient optical accessibility of Bullseye cavities. Our work highlights the potential of inverse design for advancing quantum photonic technologies.<\/p>\n\n\n <\/p>\n <\/details>\n\n\n <\/div>\n <\/div>\n\n\n\n
