AKLT Hamiltonian from Hubbard tripods
Claire Benjamin, Dániel Varjas, Gábor Széchenyi +2
We investigate how the spin-1 Affleck-Kennedy-Lieb-Tasaki (AKLT) Hamiltonian can emerge from a microscopic fermionic model based on half-filled Hubbard tripods. We first show that…
Readout sweet spots for spin qubits with strong spin-orbit interaction
Domonkos Svastits, Bence Hetényi, Gábor Széchenyi +4
Qubit readout schemes often deviate from ideal projective measurements, introducing critical issues that limit quantum computing performance. In this work, we model charge-sensing-…
Limitations of the -tensor formalism of semiconductor spin qubits
Zoltán György, András Pályi, Gábor Széchenyi
The -tensor formalism is a powerful method for describing the electrical driving of semiconductor spin qubits. However, up to now, this technique has only been applied to the si…
Practical scheme for efficient distillation of GHZ states
Áron Rozgonyi, Gábor Széchenyi, Orsolya Kálmán +1
We develop an efficient local operation and classical communication (LOCC) scheme for the distillation of Greenberger-Horne-Zeilinger (GHZ) states from tripartite systems subjected…
