Semiconductor Nanowire-Based Quantum Emulators
Abstract
Semiconductor Nanowire-Based Quantum EmulatorsOBJECTIVE:The primary objective of this project is the generation of Majorana fermi"ons in a chain of semiconductor quantum dots. Experimentally evaluate the potential of quantumemulators based on semiconductors, th"e same materials that power conventional computers but in thepresent case operated in the quantum limit. TheAPPROACH:The project will study the chains of quantum dots. Semiconductor nanowires will be used as one-dimensional templates. Their crystalline quality recently lead to the demonstration of quantum devices ranging from single spin quantum bits to superconductinginterferometers. A chain of quantum dots will be defined in a nanowire by tuning voltages on local electrostatic gates. These quantum dots can be viewed as artificial atoms because they have discrete electronic states. They will be used as lattice sites for a flexible quantum emulator: the on-site energies and couplings between the sites will be electrically controllable in situ.SOW:PI will demonstrate a highly tunable nanoscale semiconductor system capable ofperforming quantum simulations of one-dimensional quantum models. This project w"ill study thechains of quantum dots in semiconductor nanowires. We will focus on a particular onedimensionalmodel, the so-called ~""Kitaev chain~, prominent for generating Majorana fermions atthe end sites of the chain.
