Abstract : Recycling unmeasured photons in a system utilizing weak measurements can substantially improve the signal-to-noise ratio. We have performed a complete theoretical analysis of the tradeoffs, and demonstrated in a double-pass system that we could achieve an improvement by a factor of 1.36 over a system with no recycling. We also begin preliminary investigation into combining quantum states of light.
