Query: Quantum state magnification   Quantum metrology exploits entangled states of particles to improve sensing
precision beyond the limit achievable with uncorrelated particles. All previous
methods required detection noise levels below this standard quantum limit to
realize the benefits of the intrinsic sensitivity provided by these states.
Remarkably, a recent proposal has shown that, in principle, such low-noise
detection is not a necessary requirement. Here, we experimentally demonstrate a
widely applicable method for entanglement-enhanced measurements without
low-noise detection. Using an intermediate magnification step, we perform
squeezed state metrology 8 dB below the standard quantum limit with a detection
system that has a noise floor 10 dB above the standard quantum limit. Beyond
its conceptual significance, this method eases implementation complexity and is
expected to find application in next generation quantum sensors.
