  • Can Thermodynamic Behavior of Alice’s Particle Affect Bob’s Particle?
    Scientific Reports, 2020
    Co-Authors: Ali Soltanmanesh, Hamid Reza Naeij, Afshin Shafiee
    Abstract:

    We propose an experiment to investigate the possibility of long-distance thermodynamic relationships between two Entangled Particles. We consider a pair of spin- $$\frac{1}{2}$$ 1 2 Particles prepared in an Entangled singlet state in which one Particle is sent to Alice and the other to her distant mate Bob, who are spatially separated. Our proposed experiment consists of three different setups: First, both Particles are coupled to two heat baths with various temperatures. In the second setup, only Alice’s Particle is coupled to a heat bath and finally, in the last setup, only Bob’s Particle is coupled to a heat bath. We study the evolution of an open quantum system using the first law of thermodynamics based on the concepts of ergotropy, adiabatic work, and operational heat, in a quantum fashion. We analyze and compare ergotropy and heat transfer in three setups. Our results show that the heat transfer for each Entangled Particle is not independent of the thermalization process that occurs for the other one. We prove that the existence of quantum correlations affects the thermodynamic behavior of distant Particles in an Entangled state.

  • braids of Entangled Particle trajectories
    Chaos, 2010
    Co-Authors: Jean-luc Thiffeault
    Abstract:

    In many applications, the two-dimensional trajectories of fluid Particles are available, but little is known about the underlying flow. Oceanic floats are a clear example. To extract quantitative information from such data, one can measure single-Particle dispersion coefficients, but this only uses one trajectory at a time, so much of the information on relative motion is lost. In some circumstances the trajectories happen to remain close long enough to measure finite-time Lyapunov exponents, but this is rare. We propose to use tools from braid theory and the topology of surface mappings to approximate the topological entropy of the underlying flow. The procedure uses all the trajectory data and is inherently global. The topological entropy is a measure of the entanglement of the trajectories, and converges to zero if they are not Entangled in a complex manner (for instance, if the trajectories are all in a large vortex). We illustrate the techniques on some simple dynamical systems and on float data from the Labrador Sea. The method could eventually be used to identify Lagrangian coherent structures present in the flow.

  • efficient quantum key distribution using fibonacci number coding with a biased basis choice
    Information Processing Letters, 2018
    Co-Authors: Hong Lai, Mingxing Luo, Josef Pieprzyk, Mehmet A Orgun
    Abstract:

    Highlights • We find out that the sources for preparing Entangled OAM states based on a Vogel spiral with the same Fibonacci numbers, which can prepare two types of Entangled states. • The distribution of significantly different probabilities to the Entangled state photons and measurement bases during both transmission and reception, thus reducing the fraction of discarded data. • We use the close relations among Lucas sequence, Chebyshev maps and k-Chebyshev maps to greatly enhance the capacity of per Entangled Particle for key generation without the limit of spiral and OAM bandwidths. • We divide the accepted data into different subsets in terms of the types of measurements chosen and estimate an error rate for each subset separately to guarantee the security of our proposed scheme. Abstract The conjugation relation between Lucas sequence and Fibonacci sequence lead us to devise some simple modifications which essentially increases the efficiency and the capacity of quantum key distribution scheme proposed by Simon et al. (Phys. Rev. A. 87, 032312 (2013)). The first major ingredient of our scheme is the sources for preparing Entangled OAM states based on a Vogel spiral with the same Fibonacci numbers, which can prepare two types of Entangled states. The second major ingredient is the distribution of significantly different probabilities to the Entangled state photons and measurement bases during both transmission and reception, thus reducing the fraction of discarded data. The third major ingredient is that we use the close relations among Lucas sequence, Chebyshev maps and k-Chebyshev maps to greatly enhance the capacity of per Entangled Particle for key generation without the limit of spiral and OAM bandwidths. Lastly, combined the ideas proposed by Lo et al. (e-print arXiv:quant-ph/0011056) and Xue et al. (Phys. Rev. A. 65, 022317 (2002)), we divide the accepted data into different subsets in terms of the types of measurements chosen and estimate an error rate for each subset separately to guarantee the security of our proposed scheme.
