Quantum information, embodied in electron spins bound to deep donors, is coupled via optically induced electronic excitation. Gates are manipulated by magnetic fields and optical light pulses; individual gates are addressed by exploiting spatial and spectroscopic selectivity. Such quantum gates do not rely on small energy scales for operation, so might function at or near room temperature. We show the scheme can produce the classes of gates necessary to construct a universal quantum computer. date: 2003-07-16 publisher: IOP PUBLISHING LTD official_url: http://dx.doi.org/10.1088/0953-8984/15/27/102 vfaculties: VMPS rae2008: 19 oa_status: green language: eng primo: open primo_central: open_green article_type_text: Letter verified: verified_batch elements_source: Web of Science elements_id: 34710 doi: 10.1088/0953-8984/15/27/102 pii: S0953-8984(03)64964-7 lyricists_name: Fisher, Andrew lyricists_name: Greenland, Philip lyricists_name: STONEHAM, ARTHUR lyricists_id: AJFIS67 lyricists_id: PTGRE12 lyricists_id: AMSTO63 full_text_status: public publication: J PHYS-CONDENS MAT volume: 15 number: 27 pagerange: L447 - L451 refereed: TRUE issn: 0953-8984 citation: Stoneham, AM; Fisher, AJ; Greenland, PT; (2003) Optically driven silicon-based quantum gates with potential for high-temperature operation.
