Analog Quantum Computing with Fluxonium

In-person
Analog Quantum Computing leverages a controllable quantum system—such as an array of superconducting qubits—to mimic the evolution of complex quantum systems and solve problems that are otherwise classically intractable. Unlike digital quantum computing, which decomposes algorithms into discrete gates, the analog approach utilizes the natural Hamiltonian evolution. This makes it particularly robust for simulating condensed matter physics and quantum chemistry in the Noisy Intermediate-Scale Quantum (NISQ) era.
Among superconducting qubit platforms, the fluxonium qubit is a premier candidate for analog simulations. It benefits from established lithographic fabrication techniques while offering a unique combination of wide tunability, strong nonlinearity, and the capacity for strong inter-qubit coupling, making it well-suited for building high-fidelity quantum simulators.
The talk will explain the fundamentals of fluxonium qubits and show how to calibrateand correct the fast flux bias pulse to operate a single qubit. To validate the flux pulse control, the plan is to run an experiment to observe Landau-Zener transition. And potential quantum algorithms, such as variational diabatic schedules, can also be tested with the single qubit.
