Here I propose to use this nanowire qubit in order to demonstrate and control quantum entanglement, yet unexplored in semiconductor nanostructures. Our qubit uses the electron?s spin as the two-level quantum state. Electrical signals control an electron?s movement within a nanowire, which, due to the strong coupling between spin and orbit in our material, rotates the electron spin over any desired angle. This all-electrical control has enormous practical advantages, making the nanowire qubit the perfect building block for entanglement studies. I propose an unambiguous demonstration of controlled entanglement by performing two-qubit gate operations and measuring two-particle correlations that can be checked against Bell?s inequalities. To reach these ambitious goals we will first improve our material system (use core/shell wires and compare InAs with InSb) and extend our present devices to include on-chip charge sensors. My expertise from my Ph.D. research at Cornell University on ultra-fast spintronics positions me well to fulfil the technical challenges, enabling us to start the multi-qubit operations quickly. The success of this proposal will open new directions in quantum information science since our nanowire qubits can be integrated with quantum optics such that quantum information from the spins can be transported with photons over long distances.", "summary_en": "Our group has recently demonstrated a quantum bit in a semiconductor nanowire that is very easy to operate (Nature, December 23, 2010).
