Dynamic nuclear spin polarization in nitrogen-vacancy centers in diamond
Laima Busaite, Reinis Lazda, Andris Berzins +3
We studied the dynamic nuclear spin polarization of nitrogen in negatively charged nitrogen-vacancy (NV) centers in diamond both experimentally and theoretically over a wide range…
Lackadaisical quantum walks on triangular and honeycomb 2D grids
Nikolajs Nahimovs
In the typical model, a discrete-time coined quantum walk search has the same running time of for 2D rectangular, triangular and honeycomb grids. It is known…
Cross-relaxation studies with optically detected magnetic resonances in nitrogen-vacancy centers in diamond in an external magnetic field
Reinis Lazda, Laima Busaite, Andris Berzins +5
In this paper cross-relaxation between nitrogen-vacancy (NV) centers and substitutional nitrogen in a diamond crystal was studied. It was demonstrated that optically detected magne…
Ultraprecise Rydberg atomic localization using optical vortices
Ning Jia, Teodora Kirova, Gediminas Juzeliunas +2
We propose a robust localization of the highly-excited Rydberg atoms, interacting with doughnut-shaped optical vortices. Compared with the earlier standing-wave (SW)-based localiza…
A random-walk benchmark for single-electron circuits
David Reifert, Martins Kokainis, Andris Ambainis +2
Mesoscopic integrated circuits achieving high-fidelity control of elementary quantum systems require new methodology for benchmarking. We offer circuit-level statistical descriptio…
Quantum Coupon Collector
Srinivasan Arunachalam, Aleksandrs Belovs, Andrew M. Childs +3
We study how efficiently a -element set can be learned from a uniform superposition of its elements. One can think of $|S\rangle=\sum_{i\in S}|i\rang…
