Flux-tunable transmon#
Architecture#
Typical Qblox control electronics setup for a QPU of five flux-tunable transmons.#
In architectures with tunable qubits and fixed couplers, the qubit frequencies can be changed by playing a signal on the qubit’s flux line, effectively tuning the interaction strength between two neighboring qubits. Compared to an architecture where all qubit and coupler frequencies are fixed, this increases hardware overhead as well as the number of steps in a tuneup procedure. However, this design helps to mitigate crosstalk as inter-qubit coupling can be completely turned off when idling.
