Scientists of the National Research Council of Italy have succeeded in converting light into solid state for the first time. This achievement is being considered an important milestone in quantum physics.

Light Transformation to Solid: Italian scientists have created history with a unique discovery. Actually, these scientists have succeeded in converting light into solid state, which is being considered a historic discovery in quantum physics.

According to this research, light can behave as a supersolid, which is a rare state. This research, recently published in the journal ‘Nature’, is expected to revolutionize quantum computing and optical technologies.

What is supersolid light?

Actually, the supersolid state is a rare quantum state, which was considered very difficult to achieve. Earlier scientists had found it possible only at extremely cold temperatures, but now new research has shown that this state can be created under normal conditions as well. Till now, the supersolid state was seen only in Bose-Einstein condensate (BEC), which is formed when boson particles are cooled to near-zero temperature, but now, scientists from Italy’s National Research Council and the University of Pavia have shown that light can also turn into a supersolid state.

How did scientists ‘freeze’ the light?

In this study, instead of the traditional freezing process, scientists used quantum techniques. Scientists used a structure made of gallium arsenide, which had microscopic ridges. By firing a laser at this platform, hybrid light-matter particles, called polaritons, were created.

When the number of photons increased, scientists observed patterns indicating supersolidity. Researchers say, “At temperatures close to absolute zero, quantum effects emerge. This is the beginning of understanding supersolidity in light.”

Supersolid light can make quantum bits (qubits) more stable, which can accelerate quantum computing. This discovery will help in the development of optical devices, photonic circuits and sensitive quantum detectors. In the future, this technology will be further refined, which will allow supersolid light to be made in a more stable and controlled manner

Can light be made into a liquid?
Not just a solid, scientists have previously proven that light can flow like a liquid. This time, scientists have transformed it into a new state called a “quantum supersolid.”

Italian scientists create history
This achievement by Italian scientists will not only help in understanding the physical properties of light, but it can also revolutionise the development of new quantum materials and technologies. In the coming years, this discovery can lead to new possibilities in the field of quantum technology and optics

It’s fascinating how scientists are pushing the boundaries of our understanding of light! Here’s a breakdown of how Italian scientists achieved this remarkable feat, and what it really means:
Understanding the Breakthrough:

• Supersolid State:
• The key is that the scientists didn’t literally “freeze” light in the way we think of freezing water. Instead, they coaxed light into a “supersolid” state.
• A supersolid is an exotic state of matter that exhibits properties of both a solid (having a rigid structure) and a superfluid (being able to flow without friction).
• Light-Matter Interaction:
• The researchers didn’t manipulate pure light alone. They worked with a hybrid of light and matter.
• Specifically, they worked with “polaritons,” which are quasiparticles formed when light strongly interacts with matter.
• How They Did It:
• The team used quantum techniques to create conditions where these polaritons formed a supersolid. This involved carefully controlling the interactions between light and matter in a specific environment.
• They essentially caused the light to take on a crystalline structure, while also retaining the ability to behave as a superfluid.
  Key Points:
• This research expands our understanding of the fundamental nature of light and matter.
• It has potential implications for future technologies, particularly in the field of quantum computing and photonics.
• It is important to understand that the headlines of “freezing light” are somewhat of a simplification, of a very complex quantum physics experiment.
  In essence, the scientists achieved a state where light exhibited properties that were previously thought to be mutually exclusive, opening up new avenues for exploring the quantum world.
