Authors: Martinez, Daniel; Gomez, Esteban S.; Carine, Jaime; Pereira, Luciano; Delgado, Aldo; Walborn, Stephen P.; Tavakoli, Armin; Lima, Gustavo Journal: NATURE PHYSICS Publication date: 2023/02/01 DOI: 10.1038/s41567-022-01845-z Abstract: The most common form of measurement in quantum mechanics projects a wavefunction onto orthogonal states that correspond to definite outcomes. However, generalized quantum measurements that do not [...]

Quantum Approximate Optimization Algorithm Pseudo-Boltzmann States

Authors: Diez-Valle, Pablo; Porras, Diego; Garcia-Ripoll, Juan Jose Journal: PHYSICAL REVIEW LETTERS Publication date: 2023/02/02 DOI: 10.1103/PhysRevLett.130.050601 Abstract: In this Letter, we provide analytical and numerical evidence that the single-layer quantum approximate optimization algorithm on universal Ising spin models produces thermal-like states. We find that these pseudo-Boltzmann states can not be efficiently simulated on classical [...]

Quantum control of tunable-coupling transmons using dynamical invariants of motion

Authors: Espinos, H.; Panadero, I; Garcia-Ripoll, J. J.; Torrontegui, E. Journal: QUANTUM SCIENCE AND TECHNOLOGY Publication date: 2023/04/01 DOI: 10.1088/2058-9565/acbed7 Abstract: We analyze the implementation of a fast nonadiabatic CZ gate between two transmon qubits with tunable coupling. The gate control method is based on a theory of dynamical invariants which leads to reduced leakage [...]

Confining CO2 inside sI clathrate-hydrates: The impact of the CO2-water interaction on quantized dynamics

MCastell2023-07-27T12:22:01+02:00Tags: Chemistry, Multidisciplinary. |

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 [...]

Topological multimode waveguide QED

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 [...]
