Armata F, Calajo G, Jaako T, Kim MS, Rabl Pet al., Harvesting multi-qubit entanglement from ultrastrong interactions in circuit QED, Physical Review Letters, ISSN: 0031-9007

We analyze a multi-qubit circuit QED system in the regime where the qubit-photon couplingdominates over the system’s bare energy scales. Under such conditions a manifold of low-energystates with a high degree of entanglement emerges. Here we describe a time-dependent protocol forextracting these quantum correlations and converting them into well-defined multi-partite entangledstates of non-interacting qubits. Based on a combination of various ultrastrong-coupling effects theprotocol can be operated in a fast and robust manner, while still being consistent with experimentalconstraints on switching times and typical energy scales encountered in superconducting circuits.Therefore, our scheme can serve as a probe for otherwise inaccessible correlations in strongly-coupledcircuit QED systems. It also shows how such correlations can potentially be exploited as a resourcefor entanglement-based applications.

Quantum interference lies at the basis of fundamental differences betweenquantum and classical behaviors. It is thus crucial to understand theboundaries between what interference patterns can be described by classicalwave mechanics and what, on the other hand, can only be understood with aproper quantum mechanical description. While a lot of work has already beendone for the simple case of two-mode interference, the multi-mode case has notbeen fully explored yet. Here we derive bounds for classical models of lightfields in a general scenario of intensity interferometry, and we show how theycan be violated in a quantum framework. As a consequence, this violation actsas a non-classicality witness, able to detect the presence of sources withsub-Poissonian photon-number statistics. We also derive a criterion forcertifying the indivisibility of a quantum interferometer and obtain a methodto simultaneously measure the average pairwise distinguishability of the inputsources.
