Quantum-limited estimation of atmospheric turbulence via spatial mode decomposition
A. Hrebeniuk, M. Klen, I. Karuseichyk +2
We establish the ultimate precision limit for estimating the optical spatial coherence radius (Fried parameter) within a quantum metrological framework. In the weak field regime, w…
Circular-beam approximation for quantum channels in a turbulent atmosphere
I. Pechonkin, M. Klen, A. A. Semenov
The evolution of quantum states of light in free-space channels is strongly influenced by atmospheric turbulence, posing a significant challenge for quantum communication. The tran…
Time correlations in atmospheric quantum channels
M. Klen, D. Vasylyev, W. Vogel +1
Efficient transfer of quantum information between remote parties is a crucial challenge for quantum communication over atmospheric channels. Random fluctuations of the channel tran…
Numerical simulations of atmospheric quantum channels
M. Klen, A. A. Semenov
Atmospheric turbulence is one of the lead disturbance factors for free-space quantum communication. The quantum states of light in such channels are affected by fluctuating losses…
