Post-selective attack with multi-mode projection onto Fock subspace
Andrei Gaidash, George Miroshnichenko, Anton Kozubov
In this work we present a comprehensive analysis of a post-selective attack on quantum key distribution protocols employing phase-encoded linearly independent coherent states (or s…
Lindblad dynamics of open multi-mode bosonic systems: Algebra of bilinear superoperators, exceptional points and speed of evolution
Andrei Gaidash, Alexei D. Kiselev, Anton Kozubov +1
We develop the algebraic method based on the Lie algebra of quadratic combinations of left and right superoperators associated with matrices to study the Lindblad dynamics of multi…
Quantum network security dependent on connection density between trusted nodes
Andrei Gaidash, George Miroshnichenko, Anton Kozubov
In this paper we estimate how introduction of additional connections between trusted nodes through one, two and so on (i.e. connection density) to a quantum network with serial con…
Finite-key security for quantum key distribution systems utilizing weak coherent states
Anton Kozubov, Andrei Gaidash, George Miroshnichenko
In this paper we present finite-key security analysis for quantum key distribution protocol based on weak coherent (in particular phase-coded) states using a fully quantum asymptot…
Overcoming unambiguous state discrimination attack with the help of Schrödinger Cat decoy states
Andrei Gaidash, Anton Kozubov, George Miroshnichenko
In this work we propose the technique for phase-coded weak coherent states protocols utilizing two signal states and one decoy state which is found as linear combination of signal…
