Loss-aware pulse sequence optimization for generating photonic Fock states
Benjamin Stodd, Priyanshu Tiwari, René Sondenheimer +2
We investigate the preparation of frequency-tunable photonic Fock states in a hybrid cavity system consisting of a nonlinear medium and a two-level system. Employing a gradient-bas…
Generation of Tunable Entanglement from Thin-Film Lithium Niobate
Saniya Shinde, Maximilian A. Weissflog, Shaun Lung +7
Entangled photon pairs play a major role in various modern technologies such as quantum imaging, communication, and computing. Conventional photon-pair sources are often based on s…
Second-harmonic generation for enhancing the performance of diffractive neural networks
Marie Braasch, Anna Kartashova, Elena Goi +2
Diffractive neural networks (DNNs) are an emerging approach for the realization of photonic artificial intelligence, especially due to their suitability for machine-vision applicat…
Toward Spectral Engineering of Squeezed Light in High-Gain PDC
Jatin Kumar, Aleksa KrstiÄ, Sina Saravi +1
We investigated the spectral properties of squeezed light generated via parametric down-conversion in the high-gain regime, considering both unapodized and apodized dispersion-engi…
Enhanced photon-pair generation from a van der Waals metasurface
Tongmiao Fan, Yilin Tang, Shaun Lung +11
Quantum photon pairs play a pivotal role in many quantum applications. Metasurfaces, two-dimensional arrays of nanostructures, have been studied intensively to enhance and control…
Enhancing entangled two-photon absorption of Nile Red via temperature-controlled SPDC
Aleksa KrstiÄ, Tobias Bernd Gäbler, Nitish Jain +6
Entangled two-photon absorption can enable a linear scaling of fluorescence emission with the excitation power. In comparison to classical two-photon absorption with a quadratic sc…
