Algebraic approach for investigation of a multi-mode quantum system dynamics
Andrei Gaidash, Anton Kozubov, Alexei Kiselev +1
We introduce algebraic approach for superoperators that might be useful tool for investigation of quantum (bosonic) multi-mode systems and its dynamics. In order to demonstrate pot…
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…
Quantum control attack on quantum key distribution systems
Anton Kozubov, Andrei Gaidash, George Miroshnichenko
In this paper we present the quantum control attack on quantum key distribution systems. The cornerstone of the attack is that Eve can use unitary (polar) decomposition of her posi…
