Soft photon approximation in a laser field: applications
Peter A. Krachkov, Simon V. Sorokin
We apply the soft photon approximation to QED processes in a strong plane-wave laser field. New compact expressions for the emission factors are presented, which simplify the gener…
Experimental loopback boson sampling
Yu. A. Biriukov, R. D. Morozov, K. I. Okhlopkov +15
We present an experimental demonstration of boson sampling enhanced by optical feedback lines, a novel approach that introduces temporal correlations among photons to amplify compu…
Noise-tolerant tomography of multimode linear optical interferometers with single photons
Yu. A. Biriukov, R. D. Morozov, I. V. Dyakonov +11
Linear optical networks are fundamental to the advancement of quantum technologies, including quantum computing, communication, and sensing. The accurate characterization of these…
Programmable entangled qubit states on a linear-optical platform
N. N. Skryabin, Yu. A. Biriukov, M. A. Dryazgov +22
We present an experimental platform for linear-optical quantum information processing. Our setup utilizes multiphoton generation using a high-quality single-photon source, which is…
Single-quantum annihilation of positrons at low energies
Peter. A. Krachkov, Simon. V. Sorokin
We discuss the single-quantum positron annihilation with a bound electron in the near threshold region. The angular distribution and the total cross section are considered. We obta…
