A comment on: Universal control of superexchange in linear triple quantum dots with an empty mediator
Marko J. Rančić
In a recent preprint arXiv:2203.15521 G. X. Chan, P. Huang, and X. Wang claim that triple-quantum dot superexchange in a (1, 0, 1) charge configuration exhibits a change of sign (g…
Self-controlled growth of highly uniform Ge/Si hut wires for scalable qubit devices
Fei Gao, Jian-Huan Wang, Hannes Watzinger +13
Semiconductor nanowires have been playing a crucial role in the development of nanoscale devices for the realization of spin qubits, Majorana fermions, single photon emitters, nano…
Entangling Spins in Double Quantum Dots and Majorana Bound States
Marko J. Rančić, Silas Hoffman, Constantin Schrade +2
We study the coupling between a singlet-triplet qubit realized in a double quantum dot to a topological qubit realized by spatially well-separated Majorana bound states. We demonst…
Low-Error Operation of Spin Qubits with Superexchange Coupling
Marko J. Rančić, Guido Burkard
In this theoretical work we investigate superexchange, as a means of indirect exchange interaction between two single electron spin qubits, each embedded in a single semiconductor…
