Large diameter multiwall nanotubes of MgB2: structural aspects and stability of superconducting nanotubular magnesium boride
P. Banacky, P. Noga, V. Szocs +1
Based on a theoretical study, we demonstrated that magnesium boride nanotubes can reach the same stability as bulk MgB2 structure. However, most stable nanotubular forms are not st…
Electronic structure and energy level schemes of RE3+:LaSi3N5 and RE2+:LaSi3N5-xOx phosphors (RE= Ce, Pr, Nd, Pm, Sm, Eu) from first principles
Ismail A. M. Ibrahim, Zoltan Lences, Pavol Sajgalik +2
First principles calculations of rare earth (RE)-doped LaSi3N5 host lattice are performed to obtain the electronic structure, the band gap (BG), and the character of electronic tra…
Simulating long-distance entanglement in quantum spin chains by superconducting flux qubits
Stefano Zippilli, Miroslav Grajcar, Evgeni Il'ichev +1
We investigate the performance of superconducting flux qubits for the adiabatic quantum simulation of long distance entanglement (LDE), namely a finite ground-state entanglement be…
Spin relaxation anisotropy in a GaAs quantum dot
P. Scarlino, E. Kawakami, P. Stano +4
We report that the electron spin relaxation time, T1, in a GaAs quantum dot with a spin-1/2 ground state has a 180 degree periodicity in the orientation of the in-plane magnetic fi…
Generation and Detection of Spin Currents in Semiconductor Nanostructures with Strong Spin-Orbit Interaction
Fabrizio Nichele, Szymon Hennel, Patrick Pietsch +5
Storing, transmitting, and manipulating information using the electron spin resides at the heart of spintronics. Fundamental for future spintronics applications is the ability to c…
Perturbative gadgets without strong interactions
Yudong Cao, Daniel Nagaj
Perturbative gadgets are used to construct a quantum Hamiltonian whose low-energy subspace approximates a given quantum -body Hamiltonian up to an absolute error . Typically,…
Optimal single shot strategies for discrimination of quantum measurements
Michal Sedlak, Mario Ziman
We study discrimination of m quantum measurements in the scenario when the unknown measurement with n outcomes can be used only once. We show that ancilla-assisted discrimination p…
Counter-ions between or at asymmetrically charged walls: 2D free-fermion point
L. Samaj, E. Trizac
This work contributes to the problem of determining effective interaction between asymmetrically (likely or oppositely) charged objects whose total charge is neutralized by mobile…
Two Notes on Grover's Search: Programming and Discriminating
Daniel Reitzner, Mario Ziman
In this work we address two questions concerning Grover's algorithm. In the first we give an answer to the question how to employ Grover's algorithm for actual search over database…
Entanglement sensitivity to signal attenuation and amplification
Sergey N. Filippov, Mario Ziman
We analyze general laws of continuous-variable entanglement dynamics during the deterministic attenuation and amplification of the physical signal carrying the entanglement. These…
An adaptive attack on Wiesner's quantum money
Aharon Brodutch, Daniel Nagaj, Or Sattath +1
Unlike classical money, which is hard to forge for practical reasons (e.g. producing paper with a certain property), quantum money is attractive because its security might be based…
Mean-field universality class induced by weak hyperbolic curvatures
Andrej Gendiar, Michal Daniska, Roman Krcmar +1
Order-disorder phase transition of the ferromagnetic Ising model is investigated on a series of two-dimensional lattices that have negative Gaussian curvatures. Exceptional lattice…
