Electro-mechanical Casimir effect

Mikel Sanz, Witlef Wieczorek, Simon Gröblacher +1

The dynamical Casimir effect is an intriguing phenomenon in which photons are generated from vacuum due to a non-adiabatic change in some boundary conditions. In particular, it con…

Interaction of Mechanical Oscillators Mediated by the Exchange of Virtual Photon Pairs

Omar Di Stefano, Alessio Settineri, Vincenzo Macrì +5

Two close parallel mirrors attract due to a small force (Casimir effect) originating from the electromagnetic quantum vacuum uctuations of the electromagnetic field. These vacuum u…

Photodetection probability in quantum systems with arbitrarily strong light-matter interaction

Omar Di Stefano, Anton Frisk Kockum, Alessandro Ridolfo +2

Cavity-QED systems have recently reached a regime where the light-matter interaction strength amounts to a non-negligible fraction of the resonance frequencies of the bare subsyste…

Decoherence-free interaction between giant atoms in waveguide QED

Anton Frisk Kockum, Göran Johansson, Franco Nori

In quantum-optics experiments with both natural and artificial atoms, the atoms are usually small enough that they can be approximated as point-like compared to the wavelength of t…

Quantum Plasmonics with multi-emitters: Application to adiabatic control

A. Castellini, H. R. Jauslin, B. Rousseaux +4

We construct mode-selective effective models describing the interaction of N quantum emitters (QEs) with the localised surface plasmon polaritons (LSPs) supported by a spherical me…

Floquet Many-body Engineering: Topological and Many-body Physics in Phase Space Lattices

Pengfei Liang, Michael Marthaler, Lingzhen Guo

Hamiltonians which are inaccessible in static systems can be engineered in periodically driven many-body systems, i.e., Floquet many-body systems. We propose to use interacting par…

Generating Multimode Entangled Microwaves with a Superconducting Parametric Cavity

C. W. Sandbo Chang, M. Simoen, José Aumentado +7

In this Letter, we demonstrate the generation of multimode entangled states of propagating microwaves. The entangled states are generated by parametrically pumping a multimode supe…

Transmitting qubits through relativistic fields

Robert H. Jonsson, Katja Ried, Eduardo Martin-Martinez +1

Wireless communication derives its power from the simultaneous emission of signals in multiple directions. However, in the context of quantum communication, this phenomenon must be…

Period-tripling subharmonic oscillations in a driven superconducting resonator

Ida-Maria Svensson, Andreas Bengtsson, Philip Krantz +3

We have observed period-tripling subharmonic oscillations, in a superconducting coplanar waveguide resonator operated in the quantum regime, . The resonator is te…

Non-degenerate parametric resonance in tunable superconducting cavity

Waltraut Wustmann, Vitaly Shumeiko

We develop a theory for non-degenerate parametric resonance in a tunable superconducting cavity. We focus on nonlinear effects that are caused by nonlinear Josephson elements conne…

Ultrasensitive Inertial and Force Sensors with Diamagnetically Levitated Magnets

J. Prat-Camps, C. Teo, C. C. Rusconi +2

We theoretically show that a magnet can be stably levitated on top of a punctured superconductor sheet in the Meissner state without applying any external field. The trapping poten…

Quantum Signaling in Relativistic Motion and Across Acceleration Horizons

Robert H. Jonsson

The quantum channel between two particle detectors provides a prototype framework for the study of wireless quantum communication via relativistic quantum fields. In this article w…
