Exchange-interaction of two spin qubits mediated by a superconductor
Fabian Hassler, Gianluigi Catelani, Hendrik Bluhm
Entangling two quantum bits by letting them interact is the crucial requirements for building a quantum processor. For qubits based on the spin of the electron, these two-qubit gat…
Second-order coherence of microwave photons emitted by a quantum point contact
Fabian Hassler, Daniel Otten
Shot-noise of electrons that are transmitted with probability through a quantum point contact (biased at a voltage ) leads to a fluctuating current that in turn emits radi…
Measurement-induced entanglement of two transmon qubits by a single photon
Christoph Ohm, Fabian Hassler
On-demand creation of entanglement between distant qubits is a necessary ingredient for distributed quantum computation. We propose an entanglement scheme that allows for single-sh…
Changing anyonic ground degeneracy with engineered gauge fields
Emilio Cobanera, Jascha Ulrich, Fabian Hassler
For systems of lattice anyons like Majorana and parafermions, the unconventional quantum statistics determines a set of global symmetries (e.g., fermion parity for Majoranas) admit…
Majorana-assisted nonlocal electron transport through a floating topological superconductor
Jascha Ulrich, Fabian Hassler
The nonlocal nature of the fermionic mode spanned by a pair of Majorana bound states in a one-dimensional topological superconductor has inspired many proposals aiming at demonstra…
Dephasing due to quasiparticle tunneling in fluxonium qubits: a phenomenological approach
Samuele Spilla, Fabian Hassler, Anna Napoli +1
The fluxonium qubit has arisen as one of the most promising candidate devices for implementing quantum information in superconducting devices, since it is both insensitive to charg…
Simulation of supersymmetric quantum mechanics in a Cooper-pair box shunted by a Josephson rhombus
Jascha Ulrich, Daniel Otten, Fabian Hassler
Supersymmetries in quantum mechanics offer a way to obtain degeneracies in the excitation spectrum which do not originate from selection rules. The mechanism behind the degeneracie…
