Quantum search with resonances
We present a continuous time quantum search algorithm analogous to Grover’s one; in particular, the optimal search time of this algorithm is proportional to √ N . The search algorithm can be implemented using any Hamiltonian with discrete energy spectrum through excitation of resonances between the initial and the searched state. This algorithm is robust and, as in the case of Grover’s, it allo...
متن کاملClassical Resonances and Quantum Scarring
We study the correspondence between phase-space localization of quantum (quasi-)energy eigenstates and classical correlation decay, given by Ruelle-Pollicott resonances of the Frobenius-Perron operator. It will be shown that scarred (quasi-)energy eigenstates are correlated: Pairs of eigenstates strongly overlap in phase space (scar in same phase-space regions) if the difference of their eigene...
متن کاملNon-classical Correlations in the Quantum Search Algorithm
Entanglement lies at the heart of quantum mechanics and has no classical analogue. It is central to the speed up achieved by quantum algorithms over their classical counterparts. The Grover’s search algorithm is one such algorithm which enables us to achieve a quadratic speed up over any known classical algorithm that searches for an element in an unstructured database. Here, we analyse and qua...
متن کاملSearch for Baryonic Resonances
A search for narrow baryonic resonances produced in deep inelastic scattering and decaying to K s p (K s p̄) or Ξ−π− (Ξπ and their antiparticles) is carried out with the H1 detector at HERA. No signal is observed for a new baryonic state. Upper limits on σ(ep → eΘX) × BR(Θ → Kp) and on the ratio of the production rates of hypothetical baryonic states relative to the Ξ(1530) baryonic state are ob...
متن کاملIIR System Identification Using Improved Harmony Search Algorithm with Chaos
Due to the fact that the error surface of adaptive infinite impulse response (IIR) systems is generally nonlinear and multimodal, the conventional derivative based techniques fail when used in adaptive identification of such systems. In this case, global optimization techniques are required in order to avoid the local minima. Harmony search (HS), a musical inspired metaheuristic, is a recently ...
