Superconducting metamaterial transmission lines implemented with lumped circuit elements can exhibit left-handed dispersion, where the group and phase velocity have opposite sign, in a frequency range relevant for superconducting artificial atoms. Forming such line into ring coupling it to qubits at different points around results multimode bus resonator compact footprint. Using flux-tunable qubits, we characterize theoretically model variation strength between two each of ring-resonator...
Spins and oscillators are foundational to much of physics applied sciences. For quantum information, a spin <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mrow><a:mn>1</a:mn><a:mo>/</a:mo><a:mn>2</a:mn></a:mrow></a:math> exemplifies the most basic unit, qubit. High angular momentum spins (HAMSs) harmonic provide multilevel manifolds which have potential for hardware-efficient protected encodings information simulation many-body systems. In this work, we demonstrate...
Stabilizer operations are at the heart of quantum error correction and typically implemented in software-controlled entangling gates measurements groups qubits. Alternatively, qubits can be designed so that Hamiltonian corresponds directly to a stabilizer for protecting information. We demonstrate such hardware implementation stabilizers superconducting circuit composed chains $\ensuremath{\pi}$-periodic Josephson elements. With local on-chip flux charge biasing, we observe progressive...
Spins and oscillators are foundational to much of physics applied sciences. For quantum information, a spin 1/2 exemplifies the most basic unit, qubit. High angular momentum spins harmonic provide multi-level manifolds (e.g., qudits) which have potential for hardware-efficient protected encodings information simulation many-body systems. In this work, we demonstrate new control protocol that conceptually merges these disparate hardware platforms. Namely, show how modify oscillator on-demand...
