Spatial Quantum State Tomography with A Deformable Mirror
K. S. Kravtsov, A. K. Zhutov, S. P. Kulik
Quantum tomography is an essential experimental tool for testing any quantum technology implementations. Transverse spatial quantum states of light play a key role in many experime…
Practical Quantum Key Distribution with Geometrically Uniform States
Konstantin S. Kravtsov, Sergei N. Molotkov
In this paper we propose a practical quantum key distribution protocol based on geometrically uniform states and a standard decoy state technique. The protocol extends the ideas us…
Turbulence-induced optical loss and cross-talk in spatial mode multiplexed or single-mode free-space communication channels
K. S. Kravtsov, A. K. Zhutov, I. V. Radchenko +1
Single-mode or mode multiplexed free-space atmospheric optical channels draw increasingly more attention in the last decade. The scope of their possible applications spans from the…
Relativistic quantum key distribution system with one-way quantum communication
K. S. Kravtsov, I. V. Radchenko, S. P. Kulik +1
Unambiguous state discrimination (USD) is one of the major obstacles for practical quantum key distribution (QKD). Often overlooked, it allows efficient eavesdropping in majority o…
