Authors: Zambrano, Leonardo; Pereira, Luciano; Delgado, Aldo Journal: QUANTUM Publication date: 2024/02/08 DOI: Abstract: 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 insufficient to construct an informationally complete positive operator -valued measurement (ICPOVM) [...]

Journal: NATURE REVIEWS PHYSICS Publication date: 2024/01/25 DOI: 10.1038/s42254-023-00681-1 Abstract: Nanophotonics offers opportunities for engineering and exploiting the quantum properties of light by integrating quantum emitters into nanostructures, and offering reliable paths to quantum technology applications such as sources of quantum light or new [...]
Authors: Yazdi, Nahid; Garcia-Ripoll, Juan Jose; Porras, Diego; Navarrete-Benlloch, Carlos Journal: NEW JOURNAL OF PHYSICS Publication date: 2023/08/01 DOI: 10.1088/1367-2630/acf0e2 Abstract: We show that a collection of lossy multichromatic modulated qubits can be used to dissipatively engineer arbitrary Gaussian states of a set of bosonic modes. Our ideas are especially suited to superconducting-circuit architectures, where [...]
Authors: Yanes-Rodriguez, Raquel; Prosmiti, Rita Journal: MOLECULES Publication date: 2023/12/01 DOI: 10.3390/molecules28237893 Abstract: In the realm of solid water hydrostructures, helium atoms have a tendency to occupy the interstitial spaces formed within the crystal lattice of ice structures. The primary objective of this study is to examine the stability of various ice crystals when influenced [...]
Authors: Vega, C.; Porras, D.; Gonzalez-Tudela, A. Journal: PHYSICAL REVIEW RESEARCH Publication date: 2023/04/17 DOI: 10.1103/PhysRevResearch.5.023031 Abstract: Topological insulators feature a number of topologically protected boundary modes linked to the value of their bulk invariant. While in one-dimensional systems the boundary modes are zero dimensional and localized, in two-dimensional topological insulators the boundary modes are [...]
Authors: Valdes, Alvaro; Cabrera-Ramirez, Adriana; Prosmiti, Rita Journal: JOURNAL OF COMPUTATIONAL CHEMISTRY Publication date: 2023/06/30 DOI: 10.1002/jcc.27110 Abstract: We report new results on the translational-rotational (T-R) states of the CO2 molecule inside the sI clathrate-hydrate cages. We adopted the multiconfiguration time-dependent Hartree methodology to solve the nuclear molecular Hamiltonian, and to address issues on the [...]
Authors: Tabares, C.; de las Heras, A. Munoz; Tagliacozzo, L.; Porras, D.; Gonzalez-Tudela, A. Journal: PHYSICAL REVIEW LETTERS Publication date: 2023/08/14 DOI: 10.1103/PhysRevLett.131.073602 Abstract: Waveguide QED simulators are analog quantum simulators made by quantum emitters interacting with one-dimensional photonic band gap materials. One of their remarkable features is that they can be used to engineer [...]
Authors: Peñas, Guillermo F.; Puebla, Ricardo; Garcia-Ripoll, Juan Jose Journal: QUANTUM SCIENCE AND TECHNOLOGY Publication date: 2023/10/01 DOI: 10.1088/2058-9565/acf60a Abstract: Quantum state transfer is a key operation for quantum information processing. The original pitch-and-catch protocols rely on flying qubits or single photons with engineered wavepacket shapes to achieve a deterministic, fast and high-fidelity transfer. Yet, [...]
Authors: Pavlov, Venelin P.; Porras, Diego; Ivanov, Peter A. Journal: PHYSICA SCRIPTA Publication date: 2023/09/01 DOI: 10.1088/1402-4896/ace99f Abstract: We propose two critical dissipative quantum metrology schemes for single parameter estimation which are based on a quantum probe consisting of a coherently driven ensemble of N spin-1/2 particles under the effect of a collective spin decay.

Authors: Orek, Cahit; Bartolomei, Massimiliano; Coletti, Cecilia; Bulut, Niyazi Journal: MOLECULES Publication date: 2023/05/07 DOI: 10.3390/molecules28093941 Abstract: Gold(I) metal complexes are finding increasing applications as therapeutic agents against a variety of diseases. As their potential use as effective metallodrugs is continuously confirmed, the issue of their administration, distribution and delivery to desired biological targets emerges. [...]
