Quantum mechanics has revolutionised information processes like computing and communication. However, full-scale quantum networks and quantum computing are still years away. In the short term we can expect benefits from quantum technologies in the areas of sensing and metrology. In this talk I will present the foundations of quantum imaging and metrology, and explore how we can use quantum...
I will propose a technique called the "expanding ejecta method" (EEM) to determine angular diameter distances to supernovae based purely on geometry, augmenting the calibration of the cosmic distance ladder or even enabling a direct inference of the cosmic expansion rate. I will also introduce a new variant of intensity interferometry --- "extended-path intensity correlation". EPIC enables...
The Quantum Astrometry project at Brookhaven National Laboratory (USA) is working towards a demonstration of the SNSV scheme of intensity interferometry, as first proposed in Stankus et al. (2022, DOI: astro:2010.09100). By measuring the oscillation of HBT visibility between two optically-disconnected telescope stations as the Earth rotates, the SNSV scheme determines the opening angle between...
Using intensity correlations measured by intensity interferometers one can infer the angular 2-point correlation function containing precisely half the information of corresponding amplitude interferometry measurements. If one has a phase reference, say, as provided by a bright point source in the field one can recover all the information available to amplitude interferometry. I will show...
Intensity interferometry has proven to be a powerful method for measuring the angular sizes of stellar objects and is increasingly regarded as a reliable technique for achieving high-resolution imaging. With current advancements in detector technology, the time resolution has improved to the point where we are able to to resolve the shape of the correlation peaks. Such sensitivity opens the...
