Large Quantum Delocalization of a Levitated Nanoparticle using Optimal Control: Applications for Force Sensing and Entangling via Weak Forces
T. Weiss, M. Roda-Llordes, E. Torrontegui +2
We propose to optimally control the harmonic potential of a levitated nanoparticle to quantum delocalize its center-of-mass motional state to a length scale orders of magnitude lar…
Invariant-based inverse engineering of time-dependent, coupled harmonic oscillators
A. Tobalina, E. Torrontegui, I. Lizuain +2
Two-dimensional systems with time-dependent controls admit a quadratic Hamiltonian modelling near potential minima. Independent, dynamical normal modes facilitate inverse Hamiltoni…
Ultra-fast two-qubit ion gate using sequences of resonant pulses
E. Torrontegui, D. Heinrich, M. I. Hussain +2
We propose a new protocol to implement ultra-fast two-qubit phase gates with trapped ions using spin-dependent kicks induced by resonant transitions. By only optimizing the allocat…
Single-atom heat engine as a sensitive thermal probe
Amikam Levy, Moritz Göb, Bo Deng +3
We propose employing a quantum heat engine as a sensitive probe for thermal baths. In particular, we study a single-atom Otto engine operating in an open thermodynamic cycle. Owing…
Speed-up Quantum Perceptron via Shortcuts to Adiabaticity
Yue Ban, Xi Chen, E. Torrontegui +2
The quantum perceptron is a fundamental building block for quantum machine learning. This is a multidisciplinary field that incorporates abilities of quantum computing, such as sta…
Quantum control of frequency tunable transmon superconducting qubits
J. J. García-Ripoll, A. Ruiz-Chamorro, E. Torrontegui
In this work we analyze the implementation of a control-phase gate through the resonance between the and states of two statically coupled transmons. We fi…
