Multiwavelength Ultrafast Entangled Photon Sources via Femtosecond-Pumped Parametric Down-Conversion

Abstract

Multiwavelength, quantum-entangled, ultrashort-pulsed light sources are developed using a 90 fs Yb:KGW laser amplifier. Second- and third-harmonic of the 1030 nm pump produces wavelength-tunable, entangled biphotons at 810 nm, 1030 nm, and 1414 nm via spontaneous or high-gain parametric down-conversion.

Generation of Single-Mode and Multimode Bright Squeezed Vacuum above 10 14 Photons

Zijian Lyu, SHAOWEI du, Jingze Li +5 more

Squeezed states of light and entangled photon source are fundamental resources for quantum science and technology, enabling advances in quantum communication, computation, and precision metrology. Here, we experimentally demonstrate the generation of ultrabright squeezed vacuum and entangled photon pairs via type-I high-gain parametric down-conversion. Using femtosecond pump pulses at 1,030 nm, we produce ultrabright squeezed vacuum with pulses energies on the order of 10 μJ at a central wavelength of 2,060 nm, corresponding to a photon number exceeding 10 14 . By implementing SU(1,1) interferometric configuration, we achieve flexible control over the mode structure, allowing the transition between multimode entangled photon pairs and nearly single-mode squeezed states. This results provide a high-intensity quantum light source that facilitates the study of nonclassical ultrafast dynamics.

Generation and detection of entangled photon pairs

Beáta Plaskurová

In recent years, the use of entangled photons in quantum spectroscopy has gained attention, offering new possibilities for studying materials. In this work, we present an entangled photon source developed for future applications in ultrafast quantum spec- troscopy, particularly in biological research. Entangled photons at visible wavelengths are generated using pulsed type-I spontaneous parametric down-conversion (SPDC) in a Beta-Barium Borate (BBO) crystal, pumped by a 1030 nm laser after third and fourth harmonic generation. Photon detection was performed with an intensified sCMOS cam- era, enabling observation and study of spatial and, after integration of a custom-built spectrograph, spatio-energetic correlations between photon pairs. We optimized detec- tion, imaging, and data processing methods. We believe that our results, combined with the improvements we propose, form a solid foundation for integrating entangled photon pairs into time-resolved optical spectroscopy.

A Ps-Pulse Laser for Ultrafast Entanglement Generation at 42.66 Ghz Repetition Rate

Sophie Zeiger, Fabian Laudenbach, Bernhard Schrenk +2 more

Entangled-photon sources are a key element for most quantum-information applications, ranging from quantum communication systems to quantum simulators and full photonic quantum computers. Spontaneous parametric downconversion (SPDC), requiring a pump laser and a nonlinear medium, is up-to-date still the preferred technique to generate such photonic entanglement. To scale the transmission rates or gate operations of the aforementioned applications, high clock rates of the pump lasers are needed. Moreover, photonic quantum-processing algorithms require photons with not only high entanglement visibility but also high spectral indistinguishability and purity. This can either be achieved by narrow spectral filtering, costly in rate, or by suitable choice of the pump pulse length (typically in the ps range). Attempts have been made to increase the rate of conventional fs-lasers by adding multiple spatial-paths [1] but this method cannot be used to go beyond GHz repetition rates. This results in the quest to produce pump lasers with very high repetition rate, ps-pulse width and high enough power to drive the weak SPDC process.
