Bound states in the continuum in a fluxonium qutrit
María Hita-Pérez, Pedro Orellana, Juan José García-Ripoll +1
The heavy fluxonium at zero external flux has a long-lived state when coupled capacitively to any other system. We analyze it by projecting all the fluxonium relevant operators int…
Parallel tomography of quantum non-demolition measurements in multi-qubit devices
L. Pereira, J. J. García-Ripoll, T. Ramos
An efficient characterization of QND measurements is an important ingredient towards certifying and improving the performance and scalability of quantum processors. In this work, w…
Quantum Approximate Optimization Algorithm pseudo-Boltzmann states
Pablo Díez-Valle, Diego Porras, Juan José García-Ripoll
In this letter, we provide analytical and numerical evidence that the single-layer Quantum Approximate Optimization Algorithm (QAOA) on universal Ising spin models produces thermal…
Dynamical photon-photon interaction mediated by a quantum emitter
Hanna Le Jeannic, Alexey Tiranov, Jacques Carolan +11
Single photons constitute a main platform in quantum science and technology: they carry quantum information over extended distances in the future quantum internet and can be manipu…
Quantum Fourier analysis for multivariate functions and applications to a class of Schrödinger-type partial differential equations
Paula García-Molina, Javier Rodríguez-Mediavilla, Juan José García-Ripoll
In this work, we develop a highly efficient representation of functions and differential operators based on Fourier analysis. Using this representation, we create a variational hyb…
Multi-GHz repetition rate, multi-watt average power, ultraviolet laser pulses for fast trapped-ion entanglement operations
M. I. Hussain, D. Heinrich, M. Guevara-Bertsch +4
The conventional approach to perform two-qubit gate operations in trapped ions relies on exciting the ions on motional sidebands with laser light, which is an inherently slow proce…
