Solid-State Quantum Computer Based on Scanning Tunneling Microscopy

Solid-state quantum computer based on scanning tunneling microscopy.

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 app...

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...

Solid-state nuclear-spin quantum computer based on magnetic resonance force microscopy

We propose a nuclear-spin quantum computer based on magnetic resonance force microscopy ~MRFM!. It is shown that an MRFM single-electron spin measurement provides three essential requirements for quantum computation in solids: ~a! preparation of the ground state, ~b! oneand two-qubit quantum logic gates, and ~c! a measurement of the final state. The proposed quantum computer can operate at temp...
