High quality quasinormal modes of phononic crystals for quantum acoustodynamics
Aleksey N. Bolgar, Shtefan V. Sanduleanu, Aleksandr Strelnikov +1
Phononic crystals are a promising platform for the study of quantum acoustodynamics. In a recent experiment, the interaction of a superconducting quantum bit with modes of a phonon…
Gradient projection method for constrained quantum control
Oleg Morzhin, Alexander Pechen
In this work, we adopt the Gradient Projection Method (GPM) to problems of quantum control. For general -level closed and open quantum systems, we derive the corresponding adjoi…
Routing algorithm within the multiple non-overlapping paths approach for quantum key distribution networks
Evgeniy O. Kiktenko, Andrey Tayduganov, Aleksey K. Fedorov
We develop a novel key routing algorithm for quantum key distribution (QKD) networks that utilizes a distribution of keys between remote, i.e., not directly connected by a QKD link…
Intensity correlations in decoy-state BB84 quantum key distribution systems
Daniil Trefilov, Xoel Sixto, Víctor Zapatero +3
The decoy-state method is a prominent approach to enhance the performance of quantum key distribution (QKD) systems that operate with weak coherent laser sources. Due to the limite…
Effect of Etching Methods on Dielectric Losses in Transmons
T. A. Chudakova, G. S. Mazhorin, I. V. Trofimov +9
Superconducting qubits are considered as a promising platform for implementing a fault tolerant quantum computing. However, surface defects of superconductors and the substrate lea…
Transpiling quantum assembly language circuits to a qudit form
Denis A. Drozhzhin, Anastasiia S. Nikolaeva, Evgeniy O. Kiktenko +1
In this paper, we introduce the workflow for converting qubit circuits represented by Open Quantum ASseMbly format (OpenQASM, also known as QASM) into the qudit form for execution…
Quantum channels, complex Stiefel manifolds, and optimization
Ivan Russkikh, Boris Volkov, Alexander Pechen
Most general dynamics of an open quantum system is commonly represented by a quantum channel, which is a completely positive trace-preserving map (CPTP or Kraus map). Well-known re…
Some Aspects of Remote State Restoring in State Transfer Governed by XXZ-Hamiltonian
Georgii A. Bochkin, Sergei I. Doronin, Edward B. Fel'dman +4
We consider the remote state restoring and perfect transfer of the zero-order coherence matrix (PTZ) in a spin system governed by the XXZ-Hamiltonian conserving the excitation numb…
Control landscapes for high-fidelity generation of C-NOT and C-PHASE gates with coherent and environmental driving
Alexander N. Pechen, Vadim N. Petruhanov, Oleg V. Morzhin +1
High fidelity generation of two-qubit gates is important for quantum computation, since such gates are components of popular universal sets of gates. Here we consider the problem o…
Control of the von Neumann Entropy for an Open Two-Qubit System Using Coherent and Incoherent Drives
Oleg Morzhin, Alexander Pechen
This article is devoted to developing an approach for manipulating the von Neumann entropy of an open two-qubit system with coherent control and incoherent control induci…
Phenomenon of a stronger trapping behaviour in -type quantum systems with symmetry
Boris Volkov, Anastasia Myachkova, Alexander Pechen
, , (ladder), and other three-level quantum systems with one forbidden transition (referred here as -type systems) play an important role in quantum physics. Various a…
Energy control in a quantum oscillator using coherent control and engineered environment
Alexander N. Pechen, Sergey Borisenok, Alexander L. Fradkov
We develop and analyze a new method for manipulation of energy in a quantum harmonic oscillator using coherent, e.g., electromagnetic, field and incoherent control. Coherent contro…
