Logic gates in excitonic single-quantum-dot qubits

[scallen]

I am searching for physical realizations of universal logic operations (phase rotation, CNOT, Hadamard) in single-dot excitionic qubits. Phase rotations are easy to implement with sinusoidal electric fields but my literature search for CNOT and Hadamard gates runs dry. I can find them in spin state qubits or excitonic double-dot qubits. It seems like excitons are the readheaded step-child in the world of quantum computing theses days. Have these logic gates ever been implemented in this particular type of qubit?

Unfortunately, it appears that the CNOT and Hadamard gates have not yet been implemented in single-dot excitonic qubits. While there have been some attempts to implement these logic gates in spin states, most of the research to date has focused on double-dot excitonic qubits. As such, there is currently no evidence that these gates have been implemented in single-dot excitonic qubits. However, this is an active area of research and there may be progress in the near future.
