Acquisition of a superconductor deposition system for hybrid quantum computing devices
Abstract
For public releaseAcquisition of a superconductor deposition system for hybrid quantum computing devicesPO: Ian Appelbaum, ONR 312PI,: Sergey Frolov; University of PittsburghThis project will acquire and set up a vacuum system for the deposition of superconductor t,hin films that meet the newly identified requirements for advanced quantum devices. Research program that will be dramatically enhan,ced by this equipment is carried out at the University of Pittsburgh. Within this program, hybrid nanoelectronic devices that combin,e semiconductor nanostructures with superconductor shells are studied as potential hosts of exotic Majorana zero modes. Majorana mod,es are predicted to obey non-Abelian exchange rules which can be exploited for robust storage, protection and high fidelity manipula,tion of quantum information. Majorana modes are at the foundation of well-developed though so far hypothetical architectures for top,ological quantum computing. Majorana modes are also of interest from the point of view of basic science and education. Much of the p,romise of hybrid superconductor-semiconductor devices is conditional upon the quality of ingredient materials and structures, both s,emiconductors and superconductors, and especially on the quality of the interfaces between them. Majorana modes, for instance, are p,redicted to lose their topological advantages rapidly with higher interface roughness. The advanced superconductor deposition system, will be capable of both cleaning the superconductor surface and forming a sharp and smooth interface between the semiconductor and,a smooth superconductor coating layer. Studies of hybrid superconductor-semiconductor devices may lead to even broader future benefi,ts and applications such as voltage-controlled superconducting qubit operation with long coherence times.
