"Quantum Computers and Atom-Scale Electronics in Silicon"


John R. Tucker , Department of Electrical and Computer Engineering - University of Illinois at Urbana-Champaign
[Host: Olivier Pfister]
ABSTRACT:
Over the past ten years, my colleague T.-C. Shen and I have developed a process for patterning individual phosphorous donors and self-ordered arrays into silicon with atomic resolution. This technique is now employed by the Australian Centre for Quantum Computer Technology and ourselves in efforts to build a silicon quantum computer. Our current research is focused on developing planar single-electron transistors to probe the quantum states of individual P donor 'qubits' inside the silicon crystal. Thus far, we have demonstrated electron wave interference across a 10nm-linewidth Aharanov-Bohm ring. Prospects for realizing a silicon quantum computer will be outlined, along with additional thoughts on future nanoelectronics and transport experiments.
