Architecture#
Example layout of a QPU containing five spin qubits controlled using Qblox control electronics.#
The example above illustrates a typical spin-qubit QPU based on semiconductor quantum dots. This architecture consists of five quantum dots arranged to host spin qubits, each controlled through dedicated barrier and plunger gates. A central electron spin resonance (ESR) line provides microwave excitation for spin manipulation, while a nearby charge sensor enables state readout.
All gate and barrier lines are equipped with Bias-Ts, allowing the combination of fast control pulses with DC biasing on the same line. This configuration enables high-speed qubit operations without sacrificing stability in the electrostatic potential of the dots.
