Estimation of high-dimensional unitary transformations saturating the Quantum Cramér-Rao bound
J. Escandón-Monardes, D. Uzcátegui, M. Rivera-Tapia +2
We propose an estimation procedure for -dimensional unitary transformations. For , the unitary transformations close to the identity are estimated saturating the quantum Cr…
Coherent anharmonicity transfer from matter to light in the THz regime
Mauricio Arias, Johan F. Triana, Aldo Delgado +1
Optical nonlinearities are fundamental in several types of optical information processing protocols. However, the high laser intensities needed for implementing phase nonlinearitie…
Bures geodesics and quantum metrology
Dominique Spehner
We study the geodesics on the manifold of mixed quantum states for the Bures metric. It is shown that these geodesics correspond to physical non-Markovian evolutions of the system…
Non-Markovianity in High-Dimensional Open Quantum Systems using Next-generation Multicore Optical Fibers
Santiago Rojas-Rojas, Daniel Martínez, Kei Sawada +5
With the advent of quantum technology, the interest in communication tasks assisted by quantum systems has increased both in academia and industry. Nonetheless, the transmission of…
Minimal orthonormal bases for pure quantum state estimation
Leonardo Zambrano, Luciano Pereira, Aldo Delgado
We present an analytical method to estimate pure quantum states using a minimum of three measurement bases in any finite-dimensional Hilbert space. This is optimal as two bases are…
Delay-induced spontaneous dark state generation from two distant excited atoms
William Alvarez-Giron, Pablo Solano, Kanu Sinha +1
We investigate the collective non-Markovian dynamics of two fully excited two-level atoms coupled to a one-dimensional waveguide in the presence of delay. We demonstrate that analo…
