Extended Data Table 1 Exchange pulses

From: Universal control of a six-qubit quantum processor in silicon

  1. In order to achieve sufficiently high Jon/Joff, we use a combination of barrier gate pulses, where we pulse a barrier gate in between the target qubit pair to a more positive voltage and at the same time we pulse the voltage on the barrier gates on the outer side of target qubit pair to a less positive voltage. This pushes the two quantum dots towards each other further enhancing the tunnel coupling.
