The second generation of laser-interferometric gravitational wave (GW) detectors currently under construction will reach a sensitivity close to the Standard Quantum Limit, which is the equivalent of the Heisenberg Uncertainty Principle. In this seminar I will give an introduction to quantum noise and discuss various techniques that might enable us to beat the Heisenberg Limit: What is squeezed light? How can you make photons stiffer than diamond and why does that help you to detect GW? Can you use a Sagnac speedmeter to trick Heisenberg? Is the Michelson interferometer still the best configuration for third generation GW detectors such as ET and LIGO -3?
