Optimal quantum metrology for two-photon absorption
Athena Karsa, Ranjith Nair, Andy Chia +2
Two-photon absorption (TPA) is a nonlinear optical process with wide-ranging applications from spectroscopy to super-resolution imaging. Despite this, the precise measurement and c…
Energetic Considerations in Quantum Target Ranging
Athena Karsa, Stefano Pirandola
While quantum illumination (QI) can offer a quantum-enhancement in target detection, its potential for performing target ranging remains unclear. With its capabilities hinging on a…
Quantum Illumination with a generic Gaussian source
Athena Karsa, Gaetana Spedalieri, Quntao Zhuang +1
With the aim to loosen the entanglement requirements of quantum illumination, we study the performance of a family of Gaussian states at the transmitter, combined with an optimal a…
Noisy receivers for quantum illumination
Athena Karsa, Stefano Pirandola
Quantum illumination (QI) promises unprecedented performances in target detection but there are various problems surrounding its implementation. Where target ranging is a concern,…
