An error-protected cross-resonance switch in weakly-tuneable architectures
Xuexin Xu, M. Ansari
In two-qubit gates activated by microwave pulses, by turning pulse on or off, the state of qubits are swapped between entangled or idle modes. In either mode, the presence of stray…
Parasitic-free gate: A protected switch between idle and entangled states
Xuexin Xu, M. H. Ansari
We propose a gate to switch superconducting qubit pairs in and out of a two-body interaction. This gate uses cross resonance driving on a tunable circuit with adjusted parameters a…
ZZ freedom in two qubit gates
Xuexin Xu, M. H. Ansari
Superconducting qubits on a circuit exhibit an always-on state-dependent phase error. This error is due to sub-MHz parasitic interaction that repels computational levels from non-c…
Suppression of Unwanted Interactions in a Hybrid Two-Qubit System
Jaseung Ku, Xuexin Xu, Markus Brink +4
Mitigating crosstalk errors, whether classical or quantum mechanical, is critically important for achieving high-fidelity entangling gates in multi-qubit circuits. For weakly anhar…
