Abstract
Initialization, manipulation and measurement of a three-spin qubit are demonstrated using a few- electron triple quantum dot, where all operations can be driven by tuning the exchange interaction. Multiplexed reflectometry, applied to two nearby charge sensors, allows for qubit readout. Deco- herence is found to be in reasonable agreement with predictions based on gate voltage noise with a uniform power spectrum. Requirements to achieve full multi-qubit control using only exchange and electrostatic interactions are outlined.Citation
