Robust Oscillator-Mediated Phase Gates Driven by Low-Intensity Pulses
I. Arrazola, J. Casanova
Robust qubit-qubit interactions mediated by bosonic modes are central to many quantum technologies. Existing proposals combining fast oscillator-mediated gates with dynamical decou…
Selective Interactions in the Quantum Rabi Model
L. Cong, S. Felicetti, J. Casanova +3
We demonstrate the emergence of selective -photon interactions in the strong and ultrastrong coupling regimes of the quantum Rabi model with a Stark coupling term. In particular…
Measuring Entanglement in a Photonic Embedding Quantum Simulator
Juan C. Loredo, Marcelo P. Almeida, Roberto Di Candia +4
Measuring entanglement is a demanding task that usually requires full tomography of a quantum system, involving a number of observables that grows exponentially with the number of…
Entanglement Measures in Ion-Trap Quantum Simulators without Full Tomography
J. S. Pedernales, R. Di Candia, P. Schindler +4
We propose a quantum algorithm in an embedding ion-trap quantum simulator for the efficient computation of N-qubit entanglement monotones without the necessity of full tomography.…
Embedding Quantum Simulators for Quantum Computation of Entanglement
R. Di Candia, B. Mejia, H. Castillo +3
We introduce the concept of embedding quantum simulators, a paradigm allowing the efficient quantum computation of a class of bipartite and multipartite entanglement monotones. It…
Encoding relativistic potential dynamics into free evolution
C. Sabín, J. Casanova, J. J. García-Ripoll +3
We propose a method to simulate a Dirac or Majorana equation evolving under a potential with the use of the corresponding free evolution, while the potential dynamics is encoded in…
Quantum Simulation of Interacting Fermion Lattice Models in Trapped Ions
J. Casanova, A. Mezzacapo, L. Lamata +1
We propose a method of simulating efficiently many-body interacting fermion lattice models in trapped ions, including highly nonlinear interactions in arbitrary spatial dimensions…
Quantum tomography in position and momentum space
J. Casanova, C. E. Lopez, J. J. Garcia-Ripoll +2
We introduce a method of quantum tomography for a continuous variable system in position and momentum space. We consider a single two-level probe interacting with a quantum harmoni…
Quantum Simulation of the Majorana Equation and Unphysical Operations
J. Casanova, C. Sabin, J. Leon +5
A quantum simulator is a device engineered to reproduce the properties of an ideal quantum model. It allows the study of quantum systems that cannot be efficiently simulated on cla…
Quantum simulation of the Klein paradox with trapped ions
R. Gerritsma, B. Lanyon, G. Kirchmair +7
We report on quantum simulations of relativistic scattering dynamics using trapped ions. The simulated state of a scattering particle is encoded in both the electronic and vibratio…
