Quantum physics challenges our most basic concepts about physical reality. To fully understand its conceptual implications, it is essential to try to explore whether there is a fundamental boundary between the quantum and classical worlds.
Quantum optical systems are uniquely suited to this research program because they allow a high degree of experimental control and theoretical understanding. The recent impressive experimental progress in quantum optics would not have been possible without the inspiration and guidance provided by theoretical work.
My overarching research objective is to lay the theoretical groundwork for experimental research programs that promise to greatly extend the domain where quantum effects such as quantum superpositions and entanglement can be observed.
My interest is currently focused on three particular approaches that promise to make it possible to extend the quantum domain in different and complementary ways. The first approach, based on quantum repeaters, aims to extend the distance over which entanglement can be observed to the intercontinental scale, which, besides its fundamental interest, would also have important applications in quantum information processing, in particular for long-distance quantum cryptography. The second approach, based on high-gain parametric amplification of single photons, may allow quantum experiments with human eyes as detectors. The third approach, based on quantum opto-mechanical systems, may lead to the most massive quantum superpositions to date, and might make it possible to test proposals for the unification of quantum physics and gravity. All these approaches are pursued in close contact with leading experimental groups.
