Efficient State Preparation via Ion Trap Quantum Computing and Quantum Searching Algorithm

We present a scheme to prepare a quantum state in a ion trap with probability approaching to one by means of ion trap quantum computing and Grover’s quantum search algorithm acting on trapped ions. Typeset using REVTEX 1 Quantum computing [1-5] is a field at the junction of modern physics and theoretical computer science. Practical experiments involving a few quantum bits have been successfully...

Measurement and state preparation via ion trap quantum computing

We investigate in detail the effects of a QND vibrational number measurement made on single ions in a recently proposed measurement scheme for the vibrational state of a register of ions in a linear rf trap [C. D’Helon and G. J Milburn, Phys. Rev. A 54, 5141 (1996)]. The performance of a measurement shows some interesting patterns which are closely related to searching. Typeset using REVTEX 1
