Neutral atom quantum register.
We demonstrate the realization of a quantum register using a string of single neutral atoms which are trapped in an optical dipole trap. The atoms are selectively and coherently manipulated in a magnetic field gradient using microwave radiation. Our addressing scheme operates with a high spatial resolution, and qubit rotations on individual atoms are performed with 99% contrast. In a final read...
متن کاملQuantum information with Rydberg atoms
Rydberg atoms with principal quantum number n 1 have exaggerated atomic properties including dipole-dipole interactions that scale as n4 and radiative lifetimes that scale as n3. It was proposed a decade ago to take advantage of these properties to implement quantum gates between neutral atom qubits. The availability of a strong long-range interaction that can be coherently turned on and off is...
متن کاملDoes Rydberg state manipulation equal quantum computation?
Manipulation Equal Quantum Computation? Ahn et al. (1), in describing the experimental search of a database realized with Rydberg atoms, left the misleading impression that the search constituted quantum computation. Their atomic system, in the words of the accompanying Perspective, “can implement [quantum] algorithms” (2) such as the database-search algorithm proposed by Grover (3, 4). And, ac...
متن کاملquantum model for information retrieval in web 2.0
the study deals with the possibility of information loss in web 2.0 due to the interaction between the overload and the real information. using gottesman and preskill method, this investigation has proposed a mechanism to calculate the amount of information transformation in web 2.0. in this proposal, there are three different hilbert spaces that belong to the degrees of freedom of outside, ins...
