Excitation dynamics in inductively coupled fluxonium circuits

Understand

We propose a near-term quantum simulator based on the fluxonium qubits inductively coupled to form a chain.

• This system provides long coherence time, large anharmonicity, and strong coupling, making it suitable to study Ising spin models.
• At the half-flux quantum sweet spot, the system is described by the transverse field Ising model (TFIM).
• We evaluate the propagation of qubit excitations through the system.
