Universal Quantum Circuitry: Deutsch Gate Construction Using GaAs/InAs Quantum Dots
The Deutsch gate is a universal quantum logic gate. Therefore, any quantum computing task can be completed using a combination of Deutsch gates. To our knowledge no Deutsch gate has been experimentally realized so far, although a proposal exists to build a Deutsch gate using Rydberg atoms [X-F Shi, Phys. Rev. Applied 9, 051001]. We propose to incorporate two GaAs/InAs quantum dots in a larger circuit comprised of linear optical elements to create a spin-spin-photon polarization three qubit Deutsch Gate. We expand on a similar proposal for a CNOT gate [Bouwmeester et al., Phys. Rev. Lett. 104, 160503]. We display the circuit and discuss the intricacies of designing this gate and reflect on the general feasibility of gate design.
