abstract = {In the semiconductor double quantum dot singlet-triplet
qubit architecture, the decoherence caused by the qubit's
charge environment poses a serious obstacle towards large
scale quantum computing. The effects of the charge
decoherence can be mitigated by operating the qubit in the
so-called sweet spot regions where it is insensitive to
electrical noise. In this paper, we propose singlet-triplet
qubits based on two quantum dots of different sizes. Such
asymmetric double quantum dot systems allow the
implementation of exchange gates with controllable exchange
splitting J operated in the doubly occupied charge region of
the larger dot, where the qubit has high resilience to
charge noise. In the larger dot, J can be quenched to a
value smaller than the intradot tunneling using magnetic
fields, while the smaller dot and its larger splitting can
be used in the projective readout of the qubit.},
