Controlling Quantum Computing
One promising approach for scalable quantum computing is to use an alloptical architecture, in which the qubits are represented by photons and manipulated by mirrors and beam splitters. So far, researchers have demonstrated this method, called Linear Optical Quantum Computing, on a very small scale by performing operations using just a few photons. In an attempt to scale up this method to large...
متن کاملControlling blinking in multilayered quantum dots
The fluorescence intermittency of multilayered quantum dots QDs is experimentally investigated. The measured blinking statistical probabilities for QDs of different shell structures and at different excitation powers are compared with the diffusion controlled electron transfer model. The results show that the power law statistics for the “on” and “off” events depend strongly on the structure an...
متن کاملControlling quantum transport through a single molecule.
We investigate multiterminal quantum transport through single monocyclic aromatic annulene molecules, and their derivatives, using the nonequilibrium Green function approach within the self-consistent Hartree-Fock approximation. We propose a new device concept, the quantum interference effect transistor, that exploits perfect destructive interference stemming from molecular symmetry and control...

متن کاملCoarse-Grained Picture for Controlling Quantum Chaos
We propose a coarse-grained picture to analyze control problems for quantum chaos systems. Using optimal control theory, we first show that almost perfect control is achieved for random matrix systems and a quantum kicked rotor. Second, under the assumption that the controlled dynamics is well described by a Rabi-type oscillaion between unperturbed states, we derive an analytic expression for t...
