TL;DR
This paper demonstrates that heralding techniques enable noiseless attenuation of quantum states like Schrödinger cat states and squeezed vacuum states, preserving quantum coherence and interference effects without introducing noise or decoherence.
Contribution
It introduces a method for noiseless attenuation of quantum states using heralding, avoiding the noise typically associated with attenuation.
Findings
Heralding techniques enable noiseless attenuation.
Quantum interference effects are preserved.
Attenuation does not introduce noise or decoherence.
Abstract
Attenuating a quantum state using a beam splitter will introduce noise and decoherence. Here we show that heralding techniques can be used to attenuate Schr\"odinger cat states and squeezed vacuum states without any noise or decoherence [Mi\v{c}uda et al., Phys. Rev. Lett. 109, 180503 (2012)]. Noiseless attenuation also preserves quantum interference effects in nonclassical states such as squeezed vacuum states.
