Third quantization for bosons: symplectic diagonalization, non-Hermitian Hamiltonian, and symmetries
Steven Kim, Fabian Hassler
Open quantum systems that interact with a Markovian environment can be described by a Lindblad master equation. The generator of time-translation is given by a Liouvillian superope…
Optimal gauge for the multimode Rabi model in circuit QED
Marco Roth, Fabian Hassler, David P. DiVincenzo
In circuit QED, a Rabi model can be derived by truncating the Hilbert space of the anharmonic qubit coupled to a linear, reactive environment. This truncation breaks the gauge inva…
Exact Rotating Wave Approximation
Daniel Zeuch, Fabian Hassler, Jesse J. Slim +1
The Hamiltonian of a linearly driven two-level system, or qubit, in the standard rotating frame contains non-commuting terms that oscillate at twice the drive frequency, , rende…
Majorana Qubits
Fabian Hassler
Contribution to the 44th IFF Spring School held at the Forschungszentrum Jülich in 2013 on "Quantum Information Processing". The notes include a pedagogic (but incomplete) introduc…
From Majorana Fermions to Topological Order
Barbara M. Terhal, Fabian Hassler, David P. DiVincenzo
We consider a system consisting of a 2D network of links between Majorana fermions on superconducting islands. We show that the fermionic Hamiltonian modeling this system is topolo…
