SINGLE MOLECULE ARRAY ON SILICON SUBSTRATE FOR QUANTUM COMPUTER

Individual hydrogen atoms are desorbed from a hydrogen termination layer on a silicon substrate, using an STM tip, to form a pattern of exposed regions. A single donor-bearing molecule (such as phosphine) is adsorbed onto each exposed region, to form an array of donor atoms (such as phosphorous atom...

Beschreibung
Zusammenfassung:	Individual hydrogen atoms are desorbed from a hydrogen termination layer on a silicon substrate, using an STM tip, to form a pattern of exposed regions. A single donor-bearing molecule (such as phosphine) is adsorbed onto each exposed region, to form an array of donor atoms (such as phosphorous atoms). The spins of the donor atoms may be used as qubits in a solid state quantum computer. Individual hydrogen atoms are desorbed from a hydrogen terminated layer on a silicon substrate, using an STM tip, to form a pattern of exposed regions. A single donor-bearing molecule (such as phosphorous atoms). The spins of the donor atoms may be used as qubits in a slid quantum computer. Selon l'invention, des atomes individuels d'hydrogène sont désorbés à partir d'une couche à terminaison hydrogène sur un substrat de silicium, au moyen d'une pointe de microscope à effet tunnel, afin de former un motif de zones découvertes. Une molécule unique porteuse de donneurs (tels que de la phosphine) est adsorbée sur chaque zone découverte afin de former une matrice d'atomes donneurs (tels que des atomes phosphoreux). Les spins des atomes donneurs peuvent servir de bits quantiques dans un ordinateur quantique à circuits intégrés.
