WSi weak link element with a non-sinusoidal current-phase relation
Sarah Garcia Jones, Trevyn F. Q. Larson, Sai Pavan Chitta +7
Nonlinearity is an essential ingredient for encoding quantum states with non-uniform energy spacing, implementing coherent quantum gates, reading out qubits, amplifying, and mixing…
High-fidelity iSWAP gate with Double Transmon Coupler
Tarush Tiwari, Sudhir K. Sahu, Guilhem Ribeill +6
Entangling operations are at the heart of all approaches to quantum information processing. Parametric gates, in particular, offer a versatile solution to strongly couple off-reson…
Localized quasiparticles in a fluxonium with quasi-two-dimensional amorphous kinetic inductors
Trevyn F. Q. Larson, Sarah Garcia Jones, Tamás Kalmár +10
Disordered superconducting materials with high kinetic inductance are an important resource to generate nonlinearity in quantum circuits and create high-impedance environments. In…
Fast, tunable, high fidelity cZ-gates between superconducting qubits with parametric microwave control of ZZ-coupling
X. Y. Jin, K. Cicak, Z. Parrott +6
Future quantum information processors require tunable coupling architectures that can produce high fidelity logical gates between two or more qubits. Parametric coupling is a power…
