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