correlations
- Authors: Alexander V. Poshakinskiy and Alexander N. Poddubny
- Abstract summary: We study theoretically the second-order correlation function $g(2)(t)$ for photons transmitted through a periodic Bragg-spaced array of superconducting qubits, coupled to a waveguide.
We demonstrate that photon bunching and anti-bunching persist much longer than both radiative and non-radiative lifetimes of a single qubit.

- Abstract: We study theoretically the second-order correlation function $g^{(2)}(t)$ for
photons transmitted through a periodic Bragg-spaced array of superconducting
qubits, coupled to a waveguide. We demonstrate that photon bunching and
anti-bunching persist much longer than both radiative and non-radiative
lifetimes of a single qubit. The photon-photon correlations become immune to
non-radiative dissipation due to the Borrmann effect, that is a strongly
non-Markovian collective feature of light-qubit coupling inherent to the Bragg
regime. This persistence of quantum correlations opens new avenues for
enhancing the performance of setups of waveguide quantum electrodynamics.

spectroscopy [0.0]
The radiative quantum cascade, i.e. the consecutive emission of photons from a ladder of energy levels, is of fundamental importance in quantum optics.
Here, we use exciton polaritons to explore the cascaded emission of photons in the regime where individual transitions of the ladder are not resolved.
Remarkably, the measured photon-photon correlations exhibit a strong dependence on the polariton energy, and therefore on the underlying polaritonic interaction strength.
