Coherent transfer of singlet-triplet qubit states in an architecture of triple quantum dots
Coherent transfer of singlet-triplet qubit states in an architecture of triple quantum dots
We propose two schemes to coherently transfer arbitrary quantum states of the two-electron singlet-triplet qubit across a chain of three quantum dots. The schemes are based on electrical control over the detuning energy of the quantum dots. The first is a pulse-gated scheme, requiring dc pulses and engineering of inter- …
