Gravity in the quantum lab
Abstract:
Quantum experiments are reaching relativistic regimes. Quantum
communication protocols have been demonstrated at long lenghts scales and
experiments are underway to distribute entanglement between Earth and
Satellite-based links. At these regimes the Global Positioning System
requieres relativistic corrections. Therefore, it is necessary to understand
how does motion and gravity will affect long-range quantum experiments.
Interestingly, relativistic effects can also be observed at small lengths
scales. Some effects have been demonstrated in superconducting circuits
involving boundary conditions moving at relativistic speeds and quantum
clocks have been used to measure time dilation in table-top experiments. In
this talk I will present a formalism for the study of gravitational effects
on quantum technologies. This formalism is also applicable in the
development of new quantum technologies that can be used to deepen our
understanding of physics in the overlap of quantum theory and relativity.
Examples include accelerometers, gravitational wave detectors and spacetime
probes underpinned by quantum field theory in curved spacetime.
