Abstract

We propose an implementation of the spin waves for massively parallel quantum network. A spin wave based quantum network offers an advantage of random access to any qubit in the network and, consequently, the ability to recognize two qubit gates and performance gate operation between any two distant qubits. Using model simulations we illustrate the process of the two distant qubit entanglement via spin waves exchange. The utilization of spin waves allows us to avoid the most difficult single electron spin measurements procedure. Instead, qubit state recognition is accomplished by measurement of spin wave excited in a ferromagnetic layer. By estimate the proposed scheme has as high as 10⁴ ratio between quantum system coherence time and the time of a single computational step.
