Abstract
Methods and systems are described for readout of one or more spin states associated with one or more quantum dots in an array of quantum dots, wherein the method comprises: configuring or providing one or more read-out paths of connected quantum dots in the array of quantum dots, the quantum dots of at least one of the one or more read-out paths being configured close to a charge transition point such that a charge transition in one or more first quantum dots at a first end of the tuned read-out path induces a charge transition in one or more second quantum dots at a second end of the tuned read-out path, the second end being connected to a charge detector; configuring one or more quantum dots of the quantum dot array into a spin-to-charge conversion system connected to the first end of the tuned read-out path, the charge convention system including at least two connected quantum dots hosting a spin state or a quantum dot hosting a spin state connected to a reservoir; and, obtaining information about the spin state in the spin-to-charge system, the obtaining information including the charge detector measuring a charge transition in the one or more second quantum dots at a second end of the tuned read-out path.
