Quantum Susceptibilities in Time-Domain Sampling of Electric Field Fluctuations

Matthias Kizmann et al.

Summary: Electro-optic sampling is a new quantum technique that allows measurements of electric field fluctuations on subcycle time scales. By imprinting the fluctuations of a terahertz field onto the polarization properties of an ultrashort probe pulse, the statistics of the time-domain signal can be calculated, taking into account the quantum nature of the electric fields. The electro-optic process is described using a microscopic quantum theory, and the quantum response of the nonlinear medium is characterized by interactions mediated by terahertz vacuum fluctuations.

Detection of quantum-vacuum field correlations outside the light cone

Francesca Fabiana Settembrini et al.

Summary: This research demonstrates the correlation between quantum vacuum electric fields in regions outside the light-cone. According to quantum field theory, empty space is not truly empty, but filled with fluctuations known as quantum-vacuum fluctuations. These fluctuations can be observed through various phenomena. The experimental results show the existence of vacuum field correlations between non-causally connected space-time points.

Realizing a rapidly switched Unruh-DeWitt detector through electro-optic sampling of the electromagnetic vacuum

Sho Onoe et al.

Summary: A new theoretical framework is proposed to describe the experimental advances in electro-optic detection of broadband quantum states. By utilizing concepts from quantum field theory, the nonlinear interaction behind the electro-optic effect is shown to be equivalent to a Unruh-DeWitt detector coupled to a conjugate field. The analysis accurately captures the quantum nature of the vacuum and proposes a specific working regime to experimentally verify the existence of virtual photons with quantum correlations in the electromagnetic ground state.

Stochastic Path-Integral Analysis of the Continuously Monitored Quantum Harmonic Oscillator

Tathagata Karmakar et al.

Summary: This article studies the evolution of a quantum simple harmonic oscillator under simultaneous weak position and momentum measurements. By generalizing the CDJ formalism, the most likely readout paths and quantum trajectories are derived and the probability densities of the final states are calculated. The results provide insights into the energy evolution of the system during the measurement process.

Macroscopic quantum electrodynamics approach to nonlinear optics and application to polaritonic quantum-vacuum detection

Frieder Lindel et al.

Summary: This paper provides an in-depth discussion of a theoretical framework for predicting the electromagnetic field in nonlinear crystals, introduces a diagrammatic approach for representing nonlinear processes, and analyzes the parameters in electro-optic sampling experiments. The study includes analytical results for electro-optic sampling and comparisons between theoretical predictions and experimental data.
