A Quantum RAM Using Superconducting Circuits and Donors in Silicon (QURAM)
Date du début: 1 mars 2014, Date de fin: 29 févr. 2016 PROJET  TERMINÉ 

Quantum computers are devices poised to revolutionise aspects of society from fundamental science and medical research to national security. Superconducting circuits hold great promise for the development of large-scale quantum computers. However, superconducting processors currently lack a suitable memory element for the long-term storage of quantum information. The electron and nuclear spins of dopant atoms in silicon could provide a potential solution. Silicon can be isotopically purified in a nuclear spin-zero form, allowing exceptionally long spin coherence times. This research seeks to develop a quantum random access memory (quRAM), by storing the states from superconducting quantum bits in donor spins inside an isotopically enriched silicon chip.
