Noise Protected Logical Qubit in a Open Chain of Superconducting Qubits with Ultrastrong Interactions
Roberto Stassi, Shilan Abo, Daniele Lamberto +4
To achieve a fault-tolerant quantum computer, it is crucial to increase the coherence time of quantum bits. In this work, we theoretically investigate a system consisting of a seri…
Experimental Liouvillian exceptional points in a quantum system without Hamiltonian singularities
Shilan Abo, Patrycja Tulewicz, Karol Bartkiewicz +2
Hamiltonian exceptional points (HEPs) are spectral degeneracies of non-Hermitian Hamiltonians describing classical and semiclassical open systems with losses and/or gain. However,…
Experimental hierarchy of two-qubit quantum correlations without state tomography
Shilan Abo, Jan Soubusta, Kateřina Jiráková +4
A Werner state, which is the singlet Bell state affected by white noise, is a prototype example of states, which can reveal a hierarchy of quantum entanglement, steering, and Bell…
Hybrid photon-phonon blockade
Shilan Abo, Grzegorz Chimczak, Anna Kowalewska-Kudlaszyk +3
We describe a novel type of blockade in a hybrid mode generated by linear coupling of photonic and phononic modes. We refer to this effect as hybrid photon-phonon blockade and show…
Pure Dephasing of Light-Matter Systems in the Ultrastrong and Deep-Strong Coupling Regimes
Alberto Mercurio, Shilan Abo, Fabio Mauceri +5
Pure dephasing originates from the non-dissipative information exchange between quantum systems and environments, and plays a key-role in both spectroscopy and quantum information…
Two-photon blockade and photon-induced tunneling generated by squeezing
Anna Kowalewska-Kudlaszyk, Shilan Ismael Abo, Grzegorz Chimczak +3
Inspired by the recent experiment of Hamsen et al. [Phys. Rev. Lett. 118, 133604 (2017)], which demonstrated two-photon blockade in a driven nonlinear system (composed of a harmoni…
