Determining the boundary of dynamical chaos in the generalized Chirikov map via machine learning
Daniil Chernyshov, Arkady Satanin, Lev Shchur
We investigate the boundary separating regular and chaotic dynamics in the generalized Chirikov map, an extension of the standard map with a control parameter and a phase-shift…
Single-photon sources created by nature millions of years ago
D. G. Pasternak, A. M. Romshin, R. A. Khmelnitsky +6
Single photons source (SPS) is a key component required by quantum communication devices. We report the finding of bright diamond-based SPS created by nature millions of years ago.…
Speeding up qubit control with bipolar single-flux-quantum pulse sequences
Vsevolod Vozhakov, Marina Bastrakova, Nikolay Klenov +2
The development of quantum computers based on superconductors requires the improvement of the qubit state control approach aimed at the increase of the hardware energy efficiency.…
Fano-type effect in hydrogen-terminated pure nanodiamond
O. S. Kudryavtsev, R. H. Bagramov, A. M. Satanin +7
Two novel properties, unique for semiconductors: a negative electron affinity [1-2], and a high p-type surface electrical conductivity [3-4], were discovered in diamond at the end…
Picosecond operations on superconducting quantum register based on Ramsey patterns
M. V. Bastrakova, N. V. Klenov, V. I. Ruzhickiy +2
An ultrafast qubit control concept is proposed to reduce the duration of operations with a single and multiple superconducting qubits. It is based on the generation of Ramsey fring…
Classical and quantum dissipative dynamics in Josephson junctions: an Arnold problem, bifurcation and capture into resonance
Dmitrii Pashin, Arkady M. Satanin, Chang Sub Kim
We theoretically study the phase dynamics in Josephson junctions, which maps onto the oscillatory motion of a point-like particle in the washboard potential. Under appropriate driv…
Amplitude and phase effects in Josephson qubits driven by a biharmonic electromagnetic field
A. M. Satanin, M. V. Denisenko, A. I. Gelman +1
We investigate the amplitude and phase effects of qubit dynamics and excited-state population under the influence of a biharmonic control field. It is demonstrated that the biharmo…
Quantum metamaterial without local control
A. Shvetsov, A. M. Satanin, Franco Nori +2
A quantum metamaterial can be implemented as a quantum coherent 1D array of qubits placed in a transmission line. The properties of quantum metamaterials are determined by the loca…
Amplitude spectroscopy of two coupled qubits
A. M. Satanin, M. V. Denisenko, Sahel Ashhab +1
We study the effect of a time-dependent driving field with a large amplitude on a system composed of two coupled qubits (two-level systems). Using the rotating wave approximation (…
