Charge-parity qubits based on concatenation of \pi-periodic Josephson elements: Part 1
ORAL
Abstract
Superconducting qubits with topological protection against local noise hold the promise of significantly enhanced coherence times and higher gate fidelities than are possible with conventional qubits. We are pursuing a design that uses compact, high inductances and conventional Josephson junctions with individual flux control for tuning each plaquette to reach a regime with a \pi-periodic Josephson energy. Concatenating multiple \pi-periodic elements further enhances the degree of protection that can be achieved. Here we describe the design, fabrication, and flux characterization of such a qubit.
