Practical application-specific advantage through hybrid quantum computing
Michael Perelshtein, Asel Sagingalieva, Karan Pinto +7
Quantum computing promises to tackle technological and industrial problems insurmountable for classical computers. However, today's quantum computers still have limited demonstrabl…
Terahertz Kerr effect in a methylammonium lead bromide perovskite crystal
A. A. Melnikov, V. E. Anikeeva, O. I. Semenova +1
We have observed short-lived optical birefringence in a CHNHPbBr single crystal induced by a powerful nearly single-cycle terahertz pulse. Apart from the instantaneous…
Spin transport-induced damping of coherent THz spin dynamics in iron
L. Brandt, R. Verba, N. Liebing +6
We study the damping of perpendicular standing spin-waves (PSSWs) in ultrathin Fe films at frequencies up to 2.4 THz. The PSSWs are excited by optically generated ultrashort spin c…
Control of ultrashort spin current pulses in metallic multilayers
Alexey Melnikov, Liane Brandt, Niklas Liebing +3
We study the emission of femtosecond spin current pulses at Fe/Au interfaces. Using optical second harmonic generation we demonstrate the control of pulse shape and duration by var…
Effective exchange interaction for terahertz spin waves in iron layers
Liane Brandt, Ulrike Ritzmann, Niklas Liebing +5
The exchange stiffness is a central material parameter of all ferromagnetic materials. Its value controls the Curie temperature as well as the dynamic properties of spin waves to a…
Quantum walk processes in quantum devices
Anandu Kalleri Madhu, Alexey A. Melnikov, Leonid E. Fedichkin +2
Simulation and programming of current quantum computers as Noisy Intermediate-Scale Quantum (NISQ) devices represent a hot topic at the border of current physical and information s…
