• Abstract summary: We use a pair of electro-optical phase modulators to modulate the entangled probe and conjugate light beams produced by four-wave mixing in hot Rb vapor. A single phase modulator in either one of the twin beams reduces the two-mode squeezing signal, and we find that the modulations interfere nonlocally to modify the beam correlations.

• Abstract: We investigate experimentally the nonlocal phase modulation of multiple-frequency-mode, continuous-variable entangled twin beams. We use a pair of electro-optical phase modulators to modulate the entangled probe and conjugate light beams produced by four-wave mixing in hot Rb vapor. A single phase modulator in either one of the twin beams reduces the two-mode squeezing signal, and we find that the modulations interfere nonlocally to modify the beam correlations. The nonlocal modulation of the beams can produce quantum correlations among frequency modes of the multimode fields.

  We introduce randomness into artificial gauge fields by applying local random phase shifts in the modulation of lattices of optical waveguides. We demonstrate the onset of Anderson localization in 1D- and 2D-lattices of x-, and helically-modulated waveguides via randomly choosing the modulation phases of the individual waveguides.

  We develop a general theoretical framework to dynamically engineer quantum correlations in the frequency-comb emission from an array of superconducting qubits in a waveguide. We demonstrate, that when the resonance of the two qubits are periodically modulated with a $pi$ phase shift, it is possible to realize simultaneous bunching and antibunching in cross-correlations of the scattered photons from different sidebands.

  We consider an ensemble of ultracold bosonic atoms within a near-planar cavity, driven by a far detuned laser. We show that a strong, dispersive atom-photon coupling can be reached for many transverse cavity modes at once. The resulting Floquet polaritons involve a superposition of a set of cavity modes with a density of excitation of the atomic cloud.

  We study the influence of simultaneously modulating the input laser intensity and quantum dot (QD) resonance frequecy on the mean-field dynamics. A remarkably high degree of entanglement can be achieved by modulating only the QD frequency. This study opens up new possibilities for optimal control strategies and can be used for data signal transfer and storage in quantum communication platforms.

  We report on the switching dynamics of both single and coupled VO2-based oscillators, with resistive and capacitive coupling, and explore the capability of their application in neural networks. For the resistive coupling, it is shown that synchronization takes place at a certain value of the coupling resistance, though it is unstable and a synchronization failure occurs periodically. For the capacitive coupling, two synchronization modes, with weak and strong coupling, are found. The transition between these modes is accompanied by chaotic oscillations.
