【 摘 要 】

We introduce an always-on, exchange-only qubit made up of three localized semiconductor spins that offers a true sweet spot to fluctuations of the quantum dot energy levels. Both single-and two-qubit gate operations can be performed using only exchange pulses while maintaining this sweet spot. We show how to interconvert this qubit to other three-spin encoded qubits as a resource for quantum computation and communication.
