Implementation of two-qubit Rydberg operations on neutral Rb-87 atoms in systems with different intermediate states
I. V. Iukhnovets, O. V. Bychkova, I. B. Bobrov +4
This work presents an experimental setup for implementing two-qubit operations on neutral atoms (Rb) with the possibility of using two different Rydberg excitation schemes.…
Dynamics of a spin qubit in an optical dipole trap
L. V. Gerasimov, R. R. Yusupov, I. B. Bobrov +5
We present a theoretical investigation of coherent dynamics of a spin qubit encoded in hyperfine sublevels of an alkali-metal atom in a far off-resonant optical dipole trap. The qu…
Raman sideband cooling of a single atom in an optical dipole trap: Towards theoretical optimum in a three-dimensional regime
V. M. Porozova, L. V. Gerasimov, I. B. Bobrov +3
We clarify the optimal conditions for the protocol of Raman sideband cooling (RSC) of a single atom confined with a tightly focused far-off-resonant optical dipole trap (optical tw…
Reconfigurable photonics on a glass chip
Ivan Dyakonov, Ivan Pogorelov, Ivan Bobrov +5
Reconfigurability of integrated photonic chips plays a key role in current experiments in the area of linear-optical quantum computing. We demonstrate a reconfigurable multiport in…
Post-selection free spatial Bell state generation
E. V. Kovlakov, I. B. Bobrov, S. S. Straupe +1
Spatial states of single photons and spatially entangled photon pairs are becoming an important resource in quantum communication. This additional degree of freedom provides an alm…
Imaging of Spatial Correlations of Two-Photon States
Ivan B. Bobrov, Dmitry A. Kalashnikov, Leonid A. Krivitsky
We use a fiber based double slit Young interferometer for studying the far-field spatial distribution of the two-photon coincidence rate (coincidence pattern) for various quantum s…
Schmidt-like coherent mode decomposition and spatial intensity correlations of thermal light
I. B. Bobrov, S. S. Straupe, E. V. Kovlakov +1
We experimentally study the properties of coherent mode decomposition for intensity correlation function of quasi-thermal light. We use the technique of spatial mode selection deve…
Self-calibrating Tomography for Angular Schmidt Modes in Spontaneous Parametric Down-Conversion
Stanislav Straupe, Denis Ivanov, Alexander Kalinkin +3
We report an experimental self-calibrating tomography scheme for entanglement characterization in high-dimensional quantum systems using Schmidt decomposition techniques. The self-…
Angular Schmidt Modes in Spontaneous Parametric Down-Conversion
S. S. Straupe, D. P. Ivanov, A. A. Kalinkin +2
We report a proof-of-principle experiment demonstrating that appropriately chosen set of Hermite-Gaussian modes constitutes a Schmidt decomposition for transverse momentum states o…
