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,…
