Flux-qubit readout in the persistent-current basis at arbitrary bias points

2020 · Physical Review A

Common flux-qubit readout schemes are qubit dominated, meaning they measure in the energy eigenbasis of the qubit. For various applications, measurements in a basis different from the energy eigenbasis are required. Here we present an …

Universal pulses for superconducting qudit ladder gates

2024 · JuSER (Forschungszentrum Jülich)

Qudits, generalizations of qubits to multi-level quantum systems, offer enhanced computational efficiency by encoding more information per lattice cell, avoiding costly swap operations and providing even exponential speedup in some cases. Utilizing the $d$-level manifold, …
