Large baseline optical imaging assisted by single photons and linear quantum optics
Marta Maria Marchese, Pieter Kok
In this work, we show that by combining quantum metrology and networking tools, it is possible to extend the baseline of an interferometric optical telescope and thus improve diffr…
Spin-augmented observables for efficient photonic quantum error correction
Elena Callus, Pieter Kok
We demonstrate that the spin state of solid-state emitters inside micropillar cavities can serve as measure qubits in syndrome measurements. The photons, acting as data qubits, int…
Calculating Concentratable Entanglement in Graph States
Alice R. Cullen, Pieter Kok
We propose a method to calculate the purity of reduced states of graph states entirely within the stabilizer formalism, using only the stabilizer generators for a given state. We a…
Optical quantum super-resolution imaging and hypothesis testing
Ugo Zanforlin, Cosmo Lupo, Peter W. R. Connolly +3
Estimating the angular separation between two incoherent thermal sources is a challenging task for direct imaging, especially when it is smaller than or comparable to the Rayleigh…
