Proposed Universal Deutsch Gate Circuitry Using GaAs/InAs Quantum Dots

The Deutsch gate is a universal quantum logic gate, meaning that any quantum computing task can be completed using only a series of Deutsch gates. Although a proposal exists to build a Deutsch gate using Rydberg atoms [X-F Shi, Phys. Rev. Applied~\textbf{9}, 051001], to our knowledge no Deutsch gate has been experimentally realized. We propose to combine two GaAs/InAs quantum dots described by [Bouwmeester et al., Phys. Rev. Lett.~\textbf{104}, 160503] with photon polarization in a larger circuit comprised of linear optical elements to create a spin-spin-photon polarization three qubit Deutsch Gate. In this talk we display the circuit and discuss the intricacies of designing a universal gate.
