Transport Signatures of a Majorana Qubit and Read-out-induced Dephasing
Lupei Qin, Xin-Qi Li, Alexander Shnirman +1
Motivated by recent proposals of Majorana qubits and the read-out of their quantum state we investigate a qubit setup formed by two parallel topological wires shunted by a supercon…
Finding the ground state of the Hubbard model by variational methods on a quantum computer with gate errors
Jan-Michael Reiner, Frank Wilhelm-Mauch, Gerd Schön +1
A key goal of digital quantum computing is the simulation of fermionic systems such as molecules or the Hubbard model. Unfortunately, for present and near-future quantum computers…
Effects of gate errors in digital quantum simulations of fermionic systems
Jan-Michael Reiner, Sebastian Zanker, Iris Schwenk +4
Digital quantum simulations offer exciting perspectives for the study of fermionic systems such as molecules or lattice models. However, with quantum error correction still being o…
Mesoscopic electron transport and atomic gases, a review of Frank W. J. Hekking's scientific work
Luigi Amico, Denis M. Basko, F Sebastián Bergeret +8
Frank W. J. Hekking performed his PhD work on "Aspects of Electron Transport in Semiconductor Nanostructures" at the TU Delft in 1992. He then worked as a postdoc at the University…
Decoherence of a quantum two-level system by spectral diffusion
Shlomi Matityahu, Alexander Shnirman, Gerd Schön +1
We study the dephasing of an individual high-frequency tunneling two-level system (TLS) due to its interaction with an ensemble of low-frequency thermal TLSs which are described by…
Superconducting quantum metamaterials as active lasing medium: Effects of disorder
Martin Koppenhöfer, Michael Marthaler, Gerd Schön
A metamaterial formed by superconducting circuits or quantum dots can serve as active lasing medium when coupled to a microwave resonator. For these artificial atoms, in contrast t…
