    • Quantifying phonon-induced non-Markovianity in color centers in diamond 

      Norambuena, Ariel [Univ Mayor, Fac Ciencias, Ctr Opt & Informac Cuant, Santiago, Chile]; Maze, Jeronimo R.; Rabl, Peter; Coto, Raul (AMER PHYSICAL SOC, 2020)
      We propose the application of a coherence-based measure for non-Markovianity to study the dynamics of color centers in diamond, where the optical coherence between two orbital states is affected by interactions with a ...
    • Quantum Discord, Thermal Discord, and Entropy Generation in the Minimum Error Discrimination Strategy 

      Jimenez, Omar [Univ Mayor, Fac Ciencias, Ctr Opt & Informac Cuantica]; Angel Solis-Prosser, Miguel; Neves, Leonardo; Delgado, Aldo (MDPI, 2019)
      We study the classical and quantum correlations in the minimum error discrimination (ME) of two non-orthogonal pure quantum states. In particular, we consider quantum discord, thermal discord and entropy generation. We ...
    • Semi-exact solutions of sextic potential plus a centrifugal term 

      Dong, Qian; Sun, Guo-Hua; He, Bing [Ctr Opt & Informac Cuant, Univ Mayor, Chile]; Dong, Shi-Hai (SPRINGER, 2020-11)
      We revisit the one-dimensional quantum system of a sextic potential added with a centrifugal term, V(x)=ax(-2)+bx(2)+cx(4)+dx(6), where the parameters a,b,c and d are arbitrary. We find that its solutions can be expressed ...
    • Stimulated Raman adiabatic control of a nuclear spin in diamond 

      Jacques V., Hétet G., Maze J.R.; Coto, Raúl [Centro de Física y Nanotecnología, Facultad de Ciencias, Universidad Mayor, Chile] (American Physical Society, 2017)
      Coherent manipulation of nuclear spins is a highly desirable tool for both quantum metrology and quantum computation. However, most of the current techniques to control nuclear spins lack fast speed, impairing their ...
    • Storage and retrieval of interacting photons in a Rydberg medium 

      He, Bing [Univ Mayor, Ctr Quantum Opt & Quantum Informat]; Yang, Liu; Xiao, Min (AMER PHYSICAL SOC, 2019)
      Storing interacting photons in ensembles of highly excited Rydberg atoms makes it possible to realize photon-photon gates. The efficiency of stopping and retrieving pairs of single-photon pulses in any Rydberg medium is, ...
    • The power of a control qubit in weak measurements 

      Montenegro V., Eremeev V., Mundarain D., Orszag M.; Coto, Raúl [Universidad Mayor, Chile] (NATURE PUBLISHING GROUP, 2017)
      In the late 80 s, a curious effect suggested by Aharanov et al. was found to lead to an anomalous amplification based on quantum measurements of weakly coupled systems. In this paper, we investigate the quantum control of ...
    • Ultra-high optical nonreciprocity with a coupled triple-resonator structure 

      Cao, Zhen; Xie, Yi Fei; He, Bing [Ctr Opt & Informac Cuant, Univ Mayor, Chile]; Lin, Qing (IOP Publishing Ltd., 2021)
      Optical transmission nonreciprocity as a widely investigated phenomenon is essential to various applications. Many sophisticated mechanisms have been proposed and tested for achieving the optical nonreciprocity on integrated ...
    • Weak-value amplification of photon-number operators in the optomechanical interaction 

      Orszag, Miguel [Univ Mayor, Santiago, Chile]; Carrasco, Sergio (AMER PHYSICAL SOC, 2019)
      An experimental proposal is presented in which dark port postselection together with weak measurements are used to enlarge the radiation pressure effect of a single photon on a mechanical oscillator placed in the middle ...
