A novel interferometer to beat the standard quantum limit using optical
transverse modes in multimode waveguide
Jian Fu
abstract: We propose a novel interferometer by using optical transverse modes in
multimode waveguide that can beat the standard quantum limit. In the scheme,
the classical simulation of $N$-partical quantum entangled states is generated
by using $N$ independent classical fields and linear optical elements. Similar
to the quantum-enhanced measurements, the classical simulation can also achieve
$\sqrt{N}$ enhancement over the precision of the measurement $N$ times for
independent fields. Due to only using classical fields and linear optical
elements, the scheme can be realized much more easily.
