Estimating the precision for quantum process tomography
E. O. Kiktenko, D. N. Kublikova, A. K. Fedorov
Quantum tomography is a widely applicable tool for complete characterization of quantum states and processes. In the present work, we develop a method for precision-guaranteed quan…
Scalable quantum computing with qudits on a graph
E. O. Kiktenko, A. S. Nikolaeva, Peng Xu +2
We show a significant reduction of the number of quantum operations and the improvement of the circuit depth for the realization of the Toffoli gate by using qudits. This is done b…
Protecting quantum systems from decoherence with unitary operations
E. O. Kiktenko, A. S. Mastiukova, A. K. Fedorov
Decoherence is a fundamental obstacle to the implementation of large-scale and low-noise quantum information processing devices. In this work, we suggest an approach for suppressin…
Lightweight authentication for quantum key distribution
E. O. Kiktenko, A. O. Malyshev, M. A. Gavreev +4
Quantum key distribution (QKD) enables unconditionally secure communication between distinct parties using a quantum channel and an authentic public channel. Reducing the portion o…
Revealing quantum chaos with machine learning
Y. A. Kharkov, V. E. Sotskov, A. A. Karazeev +2
Understanding properties of quantum matter is an outstanding challenge in science. In this paper, we demonstrate how machine-learning methods can be successfully applied for the cl…
