Quantum Computing on the Surface of Silicon - Zahra Shaterzadeh-Yazdi

Quantum computer executes quantum algorithms to solve computational problems. This feature enables such computer to excel over its classical counterpart at some tasks, such as the exponential speedup in factorization of large prime integers. Here we present a novel architecture for quantum computer, which is quite promising based on today's nanotechnology achievements. In our scheme, information is encoded in charge qubits which are located on the Silicon surface. The charge qubit consists of an excess electron shared between a pair of dangling bonds. Logical single-qubit gates and transmission are performed by applying local electric fields. Coulomb interaction is considered to implement two-qubit gate. This scheme is proposed based on the recent successes of Dr. R. Wolkow and his group (NINT) on quantum cellular automata.
