چکیده

We propose a solid-state nuclear-spin quantum computer based on application of scanning tunneling microscopy (STM) and well-developed silicon technology. It requires the measurement of tunneling-current modulation caused by the Larmor precession of a single electron spin. Our envisioned STM quantum computer would operate at the high magnetic field (approximately 10 T) and at low temperature approximately 1 K.

Magnetic Resonance Force Microscopy and the Solid State Quantum Computer

A Quantum Computer (QC) is a device that utilizes the principles of Quantum Mechanics to perform computations. Such a machine would be capable of accomplishing tasks not achievable by means of any conventional digital computer, for instance factoring large numbers. Currently it appears that the QC architecture based on an array of spin quantum bits (qubits) embedded in a solid-state matrix is o...

Focusing quantum states on surfaces: A route towards the design of ultrasmall electronic devices

Does the size of atoms present a lower limit to the size of electronic structures that can be fabricated in solids? This limit can be overcome by using devices that exploit quantum mechanical scattering of electron waves at atoms arranged in focusing geometries on selected surfaces. Calculations reveal that features smaller than a hydrogen atom can be obtained. These structures are potentially ...

Scalable architecture for spin-based quantum computers with a single type of gate

We propose a scalable design for a solid-state spin-based quantum computer. It uses endohedral fullerenes like N@C60 or P@C60 , which can be positioned on Si surfaces with a scanning tunneling microscope. Each logical qubit is stored in two physical qubits, corresponding to the nuclear and electronic spins. We discuss the addressing of individual qubits by a magnetic field gradient, and the imp...

Scanning Tunneling Microscopy: Principle and Instrumentation

Scanning tunneling microscopy (STM) has been proven to be an extremely powerful tool for studying the electronic structures of solid-state systems. The STM topographic images, assisted by other surface analysis techniques with chemical specifity, lead to the structural determination of clean and adsorbate-covered surfaces. For example, the first atomically resolved STM image in history confirme...
