Quantum limit of precision for phase estimation in squeezing-enhanced interferometry with a single-mode readout
Dmitri B. Horoshko, Fedor Jelezko
The paper determines the ultimate precision limit for phase estimation in a squeezing‑enhanced interferometer with a single‑mode readout, showing that this scheme can achieve Heise…
Isoenergetic model for optical downconversion and error-specific limits of the parametric approximation
D. B. Horoshko, V. S. Shchesnovich
Optical downconversion is widely used for generating photon pairs, squeezed and entangled states of light, making it an indispensable tool in quantum optics and quantum information…
Low-coherence interferometry with undetected mid-infrared photons in the high-gain regime
Giovanni Zotti, Dmitri B. Horoshko, Mikhail I. Kolobov +4
We develop a high-parametric-gain SU(1,1) interferometer based on an aperiodically poled Potassium Titanyl Phosphate (apKTP) crystal, enabling frequency-domain low-coherence interf…
Time-resolved second-order autocorrelation function of parametric downconversion
D. B. Horoshko, S. Srivastava, F. SoÅnicki +4
We study a possibility of measuring the time-resolved second-order autocorrelation function of one of two beams generated in type-II parametric downconversion by means of temporal…
Interferometric sorting of temporal Hermite-Gauss modes via temporal Gouy phase
Dmitri B. Horoshko, Mikhail I. Kolobov
We propose a device consisting of Mach-Zehnder interferometers and realizing sorting of first temporal Hermite-Gauss modes of light passing though it by adjusting the acc…
