Quantum Gates and Circuits [PDF]
, 1997 A historical review is given of the emergence of the idea of the quantum logic gate from the theory of reversible Boolean gates. I highlight the quantum XOR or controlled NOT as the fundamental two-bit gate for quantum computation. This gate plays a central role in networks for quantum error correction.

Electrodynamics-based quantum gate optimization with born scattering [PDF]
Scientific ReportsIn this paper, we propose employing electron scattering to realize unitary quantum gates that are controlled by three qubits. Using Feynman’s rules, we find an expression for the transition amplitude for scattering from an external electromagnetic source.

Application of the Diamond Gate in Quantum Fourier Transformations and Quantum Machine Learning [PDF]
Phys. Rev. Applied 17, 024053 (2022), 2021 As we are approaching actual application of quantum technology, it is essential to exploit the current quantum resources in the best possible way. With this in mind, it might not be beneficial to use the usual standard gate sets, inspired from classical logic gates, when compiling quantum algorithms when other less standardized gates currently perform ...
