We propose colloidal CdSe/CdS dots in rods as nonclassical sources for quantum information technology. Such nanoemitters show specific properties such as strongly polarized emission of on-demand single photons at room temperature, dipolelike behavior and mono-exponential recombination rates, making us envision their suitability as sources of single photons with well defined quantum states in quantum cryptography based devices.

    The Einstein-Podolsky-Rosen (EPR) nonlocality puzzle has been recognized as one of the most important unresolved issues in the foundational aspects of quantum mechanics. We show that the problem is more or less entirely resolved, if the quantum correlations are calculated directly from local...

    Based on the fundamental Holevo inequality and on the direct calculations, it is argued that the number of commitments required per one bit in a key in a damping channel increases exponentially with channel length. It is shown that the conclusion drawn recently by Duan etal. [4] that the...

    Experiments with char samples provide support for the theory of EPR line shape in a system of surface paramagnetic centers with dipole–dipole interactions. It is also demonstrated that, if a strong Heisenberg exchange dominates over the dipole–dipole interactions, the EPR line of a...

    Einstein, Podolsky, and Rosen pointed out that the quantum-mechanical description of "physical reality" implies an unphysical, instantaneous action between distant measurements. To avoid such an action at a distance, these three concluded that quantum mechanics had to be incomplete. However, its...

    We analyze the quantum measurement properties of dual non-degenerate parametric amplifers in the twin-beam configuration, in the cascaded back-action-evasion configuration, and in Kerr-type photon-number quantum non-demolition measurements. It is found that Einstein-Podolsky-Rosen correlations...

    The realization of Karl Popper's EPR-like experiment by Shih and Kim (published 1999) produced the result that Popper hoped for: no "action at a distance" on one photon of an entangled pair when a measurement is made on the other photon. This experimental result is interpretable in local...

    A III-nitride-based photogated transistor using photons to control the channel width of an otherwise gateless field effect transistor (FET) is investigated. This is accomplished by stacking sequential layers of p-GaN/InGaN/n-GaN on a Si substrate in an array of nanorods. The nitride p-i-n diode...
