Quantum metrology for fundamental physics

Presented by Konrad Lehnert, JILA

Can quantum metrology and emerging quantum technologies, in some way, improve or enhance searches for fundamental physics? Indeed, the use of optical squeezing in gravitational wave observatories is a beautiful example that they can. In addition to this one prominent example, the search for dark matter may offer several other near-term experiments that can, and perhaps must, use enhanced quantum sensing methods. I’ll describe several methods for creating and efficiently measuring non-classical states in laboratory high-Q oscillators, both mechanical and electrical. In particular detail, I’ll discuss the case of searching for a hypothetical dark matter particle known as the axion and accelerating the search using quantum squeezing approaches.
