Quantum splitting of multi-qubit gates

In this study, a novel technique for the quantum splitting of multi-qubit gates is presented. This brings innumerable advantages for the analysis of quantum circuits, the design of simulators, and back-ends, which are fundamentally needed in quantum computing development environments. This technique can be applied to any gate that involves two or more qubits, facilitating its treatment during its application in configurations of the Greenberger-Horne-Zeilinger (GHZ) type for more than two entangled photons, or protocols where CNOT or Toffoli gates connect qubits that are not close, which implies the intensive use of SWAP gates. The study is completed with the application of the new technique to quantum teleportation, quantum secret sharing, and entanglement swapping.
