Wavelet Quantum Search Algorithm with Partial Information
Sangwoong Park, Joonwoo Bae, Younghun Kwon
It is questionable that Grover algorithm may be more valuable than a classical one, when a partial information is given in a unstructured database. In this letter, to consider quan…
Perturbations can enhance qauntum search
Joonwoo Bae, Younghun Kwon
In general, a quantum algorithm wants to avoid decoherence or perturbation, since such factors may cause errors in the algorithm. In this letter, we will supply the answer to the i…
Ion Trap Proposal for Quantum Search
Joonwoo Bae, Younghun Kwon
In this letter, we show that the laser Hamiltonian can perform the quantum search. We also show that the process of quantum search is a resonance between the initial state and the…
Maximum Speedup in Quantum Search : O(1) Running Time
Joonwoo Bae, Younghun Kwon
Recently the continuous time algorithm based on the generalized quantum search Hamiltonian was presented. In this letter, we consider the running time of the generalized quantum se…
