N2 - We show how single quantum dots, each hosting a singlet–triplet qubit, can be placed in arraysto build a spin quantum cellular automaton. A fast (∼10 ns) deterministic coherent singlet–tripletfiltering, as opposed to current incoherent tunneling/slow-adiabatic based quantum gates(operation time ∼300 ns), can be employed to produce a two-qubit gate through capacitive(electrostatic) couplings that can operate over significant distances. This is the coherent versionof the widely discussed charge and nano-magnet cellular automata, and would increase speed,reduce dissipation, and perform quantum computation while interfacing smoothly with itsclassical counterpart. This combines the best of two worlds—the coherence of spin pairs knownfrom quantum technologies, and the strength and range of electrostatic couplings from thecharge-based classical cellular automata. Significantly our system has zero electric dipolemoment during the whole operation process, thereby increasing its charge dephasing time.
