Exploiting Many-Body Bus States for Multi-Qubit Entanglement
Abstract
A spin bus is formed from a linear array of quantum dots, with one electron per dot, and strong, always-on exchange interactions. When the spin bus is coupled to external spin qubits, it provides a mechanism for mediating effective long-range interactions. In this project, our efforts were divided between three main tasks: (1) to develop multi-qubit entangling protocols using the spin-bus; (2) to clarify bus decoherence properties and to optimize the robustness of bus operations; (3) to investigate methods of bus operation that could be enhanced in the vicinity of a quantum phase transition.
