Nonequilibrium Green's Function simulation of Cu2O photocathodes for photoelectrochemical hydrogen production
Lassi Hällström, Ilkka Tittonen
In this work we present a simulation of the semiconductor electrodes of photoelectrochemical (PEC) water splitting cells based on the nonequilibrium Green's function (NEGF) formali…
Exploring the optimality of approximate state preparation quantum circuits with a genetic algorithm
Tom Rindell, Berat Yenilen, Niklas Halonen +3
We study the approximate state preparation problem on noisy intermediate-scale quantum (NISQ) computers by applying a genetic algorithm to generate quantum circuits for state prepa…
On quantum factoring using noisy intermediate scale quantum computers
Vivian Phan, Arttu Pönni, Matti Raasakka +1
We study the performance and resource usage of the variational quantum factoring (VQF) algorithm for different instance sizes and optimization algorithms. Our simulations show bett…
Large-area implementation and critical evaluation of the material and fabrication aspects of a thin-film thermoelectric generator based on aluminum-doped zinc oxide
Kirsi Tappura, Taneli Juntunen, Kaarle Jaakkola +4
A large-area thermoelectric generator (TEG) utilizing a folded thin-film concept is implemented and the performance evaluated for near room temperature applications having modest t…
Broadband laser polarization control with aligned carbon nanotubes
He Yang, Bo Fua, Diao Lia +12
We introduce a simple approach to fabricate aligned carbon nanotube (ACNT) device for broadband polarization control in fiber laser systems. The ACNT device was fabricated by pulli…
Unpolarized, incoherent repumping light for prevention of dark states in a trapped and laser-cooled single ion
T. Lindvall, T. Fordell, I. Tittonen +1
Many ion species commonly used for laser-cooled ion trapping studies have a low-lying metastable 2D3/2 state that can become populated due to spontaneous emission from the 2P1/2 ex…
