A new nanometer-scale measurement tool exploits the quantum properties of light for better precision and speed

Summary

Nutrition label

90% Informative

University of Illinois developed new tool for precision measurement at the nanometer scale in scenarios where background noise and optical loss from the sample are present.

New optical interferometry technology leverages quantum properties of light to enable faster and more precise measurements than widely used classical and quantum techniques can achieve.

Technology has ready applications in medical diagnostics, remote system monitoring, material characterization, and material characterization.

Entanglement is a quantum phenomenon in which the states of two particles are linked, regardless of the distance separating them.

By entangling a property of the photons, in this case their color, the interferometer sensitivity increases.

The greater the difference in the photons' colors, the greater the sensitivity.

The new technology holds strong implications for applications across many fields.
