LIGO Enhances Gravitational Wave Detection with Squeezed Light Technology: A Breakthrough in Sensitivity

Squeezed Light Technology

Introduction to Squeezed Light Technology

A research team at LIGO in the U.S. has designed a squeezed light system aimed at boosting the sensitivity of gravitational wave detection.

Key Findings Published in Science

Published in the journal Science, the group's paper describes how their changes to the observatory reduced flicking, allowing them to detect more gravitational waves.

Insights from Yoichi Aso

In a Perspective published in the same journal, Yoichi Aso of the National Astronomical Observatory of Japan explains LIGO's functionality and how the team has enhanced its detection sensitivity.

Historical Context of LIGO's Achievements

In 2017, Caltech's team received the Nobel Prize in Physics for their pivotal role in developing LIGO, which enabled the groundbreaking detection of gravitational waves in 2015. These space-time distortions validated theories first introduced by Albert Einstein. Since then, the LIGO team has consistently detected gravitational waves while striving to enhance detection precision.

How LIGO Operates

LIGO operates by dividing a laser beam and directing the resulting beams through two long, perpendicular tunnels before reflecting them back with mirrors.

Any discrepancies in the beams signal the presence of gravitational waves, which stretch space-time within the tunnel arms.

Continuous Efforts to Enhance Sensitivity

Since its inception, LIGO scientists have recognized the challenge of distinguishing gravitational waves from quantum field fluctuations, prompting continuous efforts to enhance the observatory's sensitivity.

Recent Technological Advancements

In this latest advancement, the team integrated a custom-designed crystal into the detector, along with new mirrors and lenses. This allowed them to "Squeeze" the light in the beams into a quantum state, effectively reducing flickering.

Testing and Results of Recent Enhancements

The first round of testing showed that the improvements were increasing sensitivity to high-frequency gravitational waves only, prompting further modifications to capture lower-frequency waves as well.

Impact of Enhancements on Gravitational Wave Detection

The combined enhancements had what the team called a "Stunning Effect," doubling the number of detected gravitational waves. This, they observed, enables them to explore more expansive regions of the universe and potentially unlock new scientific discoveries, including the study of black holes that merged close to the era when the first stars formed.

NASA chile scientists comet 3i atlas nickel mystery

NASA and Chilean Scientists Study 3I/ATLAS, A Comet That Breaks the Rules Interstellar visitors are rare guests in our Solar System , but when they appear they often rewrite the rules of astronomy. Such is the case with 3I/ATLAS , a fast-moving object that has left scientists puzzled with its bizarre behaviour. Recent findings from NASA and Chilean researchers reveal that this comet-like body is expelling an unusual plume of nickel — without the iron that typically accompanies it. The discovery challenges conventional wisdom about how comets form and evolve, sparking both excitement and controversy across the scientific community. A Cosmic Outsider: What Is 3I/ATLAS? The object 3I/ATLAS —the third known interstellar traveler after "Oumuamua (2017) and 2I/Borisov (2019) —was first detected in July 2025 by the ATLAS telescope network , which scans he skies for potentially hazardous objects. Earlier images from Chile's Vera C. Rubin Observatory had unknowingly captured it, but ...

Quantum neural algorithms for creating illusions

Quantum Neural Networks and Optical Illusions: A New Era for AI? Introduction At first glance, optical illusions, quantum mechanics, and neural networks may appear unrelated. However, my recent research in APL Machine Learning Leverages "quantum tunneling" to create a neural network that perceives optical illusions similarly to humans. Neural Network Performance The neural network I developed successfully replicated human perception of the Necker cube and Rubin's vase illusions, surpassing the performance of several larger, conventional neural networks in computer vision tasks. This study may offer new perspectives on the potential for AI systems to approximate human cognitive processes. Why Focus on Optical Illusions? Understanding Visual Perception O ptical illusions mani pulate our visual  perce ption,  presenting scenarios that may or may not align with reality. Investigating these illusions  provides valuable understanding of brain function and dysfunction, inc...

fractal universe cosmic structure mandelbrot

Is the Universe a Fractal? Unraveling the Patterns of Nature The Cosmic Debate: Is the Universe a Fractal? For decades, cosmologists have debated whether the universe's large-scale structure exhibits fractal characteristics — appearing identical across scales. The answer is nuanced: not entirely, but in certain res pects, yes. It's a com plex matter. The Vast Universe and Its Hierarchical Structure Our universe is incredibly vast, com prising a p proximately 2 trillion galaxies. These galaxies are not distributed randomly but are organized into hierarchical structures. Small grou ps ty pically consist of u p to a dozen galaxies. Larger clusters contain thousands, while immense su perclusters extend for millions of light-years, forming intricate cosmic  patterns. Is this where the story comes to an end? Benoit Mandelbrot and the Introduction of Fractals During the mid-20th century, Benoit Mandelbrot introduced fractals to a wider audience . While he did not invent the conce pt —...
