Comment on 'Collectively enhanced quantum measurements at the Heisenberg limit'
D. Ballester, Yu. V. Arkhipov, I. M. Tkachenko
In a seminal paper [8] it was shown that Heisenberg-limited measurements could be achieved without using entangled states by coupling the quantum resources to a common environment…
Quantum Simulations of Relativistic Quantum Physics in Circuit QED
J. S. Pedernales, R. Di Candia, D. Ballester +1
We present a scheme for simulating relativistic quantum physics in circuit quantum electrodynamics. By using three classical microwave drives, we show that a superconducting qubit…
Path Entanglement of Continuous-Variable Quantum Microwaves
E. P. Menzel, R. Di Candia, F. Deppe +13
Path entanglement constitutes an essential resource in quantum information and communication protocols. Here, we demonstrate frequency-degenerate entanglement between continuous-va…
Validity of resonant two-qubit gates in the ultrastrong coupling regime of circuit QED
Y. M. Wang, D. Ballester, G. Romero +2
We investigate theoretically the performance of two-qubit resonant gates in the crossover from the strong to the ultrastrong coupling (USC) regime of light-matter interaction in ci…
Ultrafast Quantum Gates in Circuit QED
G. Romero, D. Ballester, Y. M. Wang +2
We present a method of implementing ultrafast two-qubit gates valid for the ultrastrong coupling (USC) and deep strong coupling (DSC) regimes of light-matter interaction, consideri…
Quantum Simulation of the Ultrastrong Coupling Dynamics in Circuit QED
D. Ballester, G. Romero, J. J. García-Ripoll +2
We propose a method to get experimental access to the physics of the ultrastrong (USC) and deep strong (DSC) coupling regimes of light-matter interaction through the quantum simula…
