We present a quantum algorithm for approximating maximum independent sets of graph based on non-Abelian adiabatic mixing in the sub-Hilbert space degenerate ground states, which generates annealing secondary Hamiltonian. For both sparse and dense random graphs G , numerical simulation suggests that our average finds an set size close to α ( ) low polynomial time. The best classical algorithms, ...

Quantum metrology promises greater sensitivity for optical phase measurements than could ever be achieved classically. Here, we present a theory of the phase sensitivity for the general case where the detection probability is given by an N photon interference fringe. We find that the phase sensitivity has a complicated dependence on both the intrinsic efficiency of detection η and the interfere...

Various bright-field (BF) imaging modes are available in scanning transmission electron microscopy (STEM). The mode equivalent to phase contrast imaging in conventional high-resolution transmission electron microscopy (TEM) involves a detector about an order of magnitude smaller than the convergence angle of the probe. This means a large proportion of the incident electrons go to waste as most ...

Abstract We introduce maximum-likelihood fragment tomography (MLFT) as an improved circuit cutting technique for running clustered quantum circuits on devices with a limited number of qubits. In addition to minimizing the classical computing overhead methods, MLFT finds most likely probability distribution output circuit, given measurement data obtained from circuit’s fragments. demonstrate ben...

Monothiolate protected gold nanoclusters with near IR luminescence underwent a five-toten fold enhancement of quantum efficiency by heating in the presence of excess thiols. Two monothiolate nanoclusters, mercaptosuccinic acid and tiopronin, were shown to benefit from this procedure. Emission maximum around 700-900 nm is favorable for bioimaging applications due to reduction of background signa...

The role of some glass network modifiers on the quantum efficiency of the near-infrared fluorescence from the 3 H 4 level of Tm 3+ ion in silica-based doped fibres is studied. Modifications of the core composition affect the spectroscopic properties of Tm 3+ ion. Adding 17.4 mol% of AlO 3/2 to the core glass caused an increase of the 3 H 4 level lifetime up to 50 µs, 3.6 times higher than in pu...

CdSe quantum dots were in situ deposited on various structures of TiO2 photoanode by successive ionic layer adsorption and reaction (SILAR). Various sensitized TiO2 structures were integrated as a photoanode in order to make quantum dot sensitized solar cells. High power conversion efficiency was obtained; 2.89 % (Voc=524 mV, Jsc=9.78 mA/cm2, FF=0.56) for the cells that sensitized by SILAR meth...
