Quantum Computation by Pairing Trapped Ultracold Ions
Feng Mang, Xiwen Zhu, Kelin Gao, Lei Shi · Chinese Physics Letters · 2001
Superpositional wavefunction oscillations for the implementation of quantum algorithms modify the desired interference required for the quantum computation. We propose a scheme with trapped ultracold ion-pairs being qubits to diminish the detrimental effect of the wavefunction oscillations, which is applied to the two-qubit Grover's search. It can be also found that the qubits in our scheme are more robust against the decoherence caused by the environment, and the model is scalable.
