AI summary

Techniques for providing an optimized quantum computing model are described. In operation, a gate teleportation circuit for a predetermined number of qubits is obtained. The gate teleportation circuit is then segmented into multiple sub-circuits. A gate teleportation operation is then performed on each of the multiple sub-circuits wherein the gate teleportation operation on each of the multiple sub-circuits is performed based on the at least one qubit of a given sub-circuit and an output of a gate teleportation operation performed on a sub-circuit which is previous to the given sub-circuit. An output of the gate teleportation operation performed on the last sub-circuit from the multiple sub-circuits is then measured.
