Qudit-native simulation of the Potts model
Maksim A. Gavreev, Evgeniy O. Kiktenko, Aleksey K. Fedorov +1
Simulating entangled, many-body quantum systems is notoriously hard, especially in the case of high-dimensional nature of physical underlying objects. In this work, we propose an a…
Transition-aware decomposition of single-qudit gates
Denis A. Drozhzhin, Evgeniy O. Kiktenko, Aleksey K. Fedorov +1
Quantum computation with -level quantum systems, also known as qudits, benefits from the possibility to use a richer computational space compared to qubits. However, for an arbi…
Coherence restoring in communication line via controlled interaction with environment
E. B. Fel'dman, I. D. Lazarev, A. N. Pechen +1
We consider the state-restoring protocol based on the controlled interaction of a linear chain with environment through { incoherent control by} the specially adjusted step-wise ti…
Analog Circuit-QED Simulator of Quantum Spin Dynamics Through the Extended Bose-Hubbard Model
Ivan V. Dudinets, Jaehee Kim, Tomás Ramos +3
We propose and validate a framework for analog simulation of the Heisenberg spin model using a circuit quantum electrodynamics (circuit-QED) platform. To this end, we develop a con…
Regularizing quantum loss landscapes by noise injection
Daniil S. Bagaev, Maxim A. Gavreev, Alena S. Mastiukova +2
The difficulty of training variational quantum algorithms and quantum machine learning models is well established. In particular, quantum loss landscapes are often highly non-conve…
Optical-pumping attack on a quantum key distribution laser source
Maxim Fadeev, Anastasiya Ponosova, Qingquan Peng +3
We report a new type of vulnerability in practical implementations of quantum key distribution systems. We show that it is possible to increase the pulse energy of a source laser d…
Simulating methylamine using symmetry adapted qubit-excitation-based variational quantum eigensolver
Konstantin M. Makushin, Aleksey K. Fedorov
In this work, we propose and analyze optimization strategies for the VQE algorithm that combine various methods, including molecular point group symmetries (symmetry adaptation), c…
