## "Hybrid oscillator-qubit quantum processors: Instruction set architectures, abstract machine models, and applications"

#### Presented by Steve Girvin, Yale University

Thursday, November 12, 2026, 12:00 pm — Videoconference / Virtual Event (visit link above to register to get zoom link)

This tutorial offers a pedagogical guide to hybrid quantum processors that integrate discrete-variable (DV) qubits and continuous-variable (CV) oscillators. Aimed at computer scientists, engineers, and physicists, it provides an overview of the experimental, algorithmic, and architectural aspects of this novel and rapidly developing hardware model. Experimental realizations of this model include superconducting, trapped-ion, and neutral-atom platforms. By combining DV and CV components, hybrid oscillator-qubit processors enable a powerful new paradigm that offers complementary strengths for quantum control, error correction, computation, and simulation. Working toward the goal of a full-stack system connecting applications to CV-DV hardware, we define and formulate abstract machine models and instruction set architectures. These essential abstractions enable codesign of hardware and software, and resource estimation for exploring the potential of current and future hardware for computational and simulation tasks. Using these abstractions, we present both new and existing examples that illustrate the benefits of hybrid CV-DV processors relative to traditional DV-only hardware in computation as well as quantum simulation of physical models. Examples include algorithms for transferring states between DV and CV systems, performing the quantum Fourier transform, and simulation of lattice gauge theories. Relative to qubit-only hardware, the bosonic degrees of freedom natively available in hybrid architectures can substantially reduce the circuit complexity of simulations for physical models containing bosons. A key technique is the extension of quantum signal processing ideas to CV-DV systems. This work is intended to serve as a timely and comprehensive guide to this relatively unexplored yet promising approach to quantum computation and to provide a road map to guide future development.

Starts at 12:00 p.m. ET/9:00 a.m. PT.

## On the Road to SC26

As SC25 concludes in St. Louis, the high performance computing (HPC) community sets its sights on the next stop along the historic Route 66 – Chicago, host city of the next SC Conference. SC26 will be led by General Chair Kevin Hayden.

“I am humbled to have been chosen as the General Chair for SC26 – in my hometown of Chicago, no less,” said Hayden, who also serves as Senior Network Engineer at the Department of Energy (DOE)’s Argonne National Laboratory. “The current HPC landscape is marked by realizing discovery at light speed, driven by rapid advancements in artificial intelligence, quantum computing, quantum networks, and exascale systems. I’m eager to see how they converge at SC26.”

#### HPC Unites.

SC26 is where the HPC community comes together to make technological and research progress, enlighten and empower all people, eliminate barriers to opportunities, chart the course for computing’s impact in the world – and we have fun doing it.
