World’s First ‘Supersolid’ Created from Light: A Groundbreaking Discovery

In a major scientific breakthrough, researchers have successfully transformed light into a supersolid—a new phase of matter that combines properties of both superfluids and solids. This discovery, published on March 5 in Nature, has profound implications for quantum computing, materials science, and energy storage. Scientists at CNR-INO, CNR-Nanotec, and the University of Pavia have demonstrated that this light-based supersolid maintains a coherent quantum droplet structure while allowing friction-free flow, a property unique to superfluids. This milestone opens new avenues in understanding light-matter interactions and may lead to advanced photonic applications in the future.

Key Highlights of the Discovery

1. What is a Supersolid?

• A supersolid is a unique state of matter that behaves both like a solid and a superfluid.
• It has an ordered crystalline structure but can flow without friction, similar to a superfluid.
• The newly created supersolid is composed of light, challenging traditional views of light as pure energy.

2. How Was the Light-Based Supersolid Created?

• Researchers used semiconductor nanostructures to manipulate light into a supersolid phase.
• The experiment involved quantum droplets arranged periodically, allowing them to flow without disruption while maintaining their spatial arrangement.
• This is a novel approach, differing from previous atomic-based supersolids.

3. Potential Applications

• Quantum Computing: Supersolids could enhance qubit stability in quantum processors.
• Materials Science: Understanding supersolids could lead to new high-performance materials.
• Energy Storage: Exploring light-based supersolids may revolutionize photonic energy storage.
• Light-Emitting Devices: This discovery could enable next-generation optical technologies.

4. Expert Insights

• Iacopo Carusotto (CNR-INO): Describes the supersolid as a fluid with coherent quantum droplets maintaining a crystalline order.
• Dimitrios Trypogeorgos (CNR-Nanotec): Emphasizes that this is not just an atomic analogy but a fundamentally new approach to supersolidity.
• Daniele Sanvitto (CNR-Nanotec): Highlights its potential to bridge the gap between fundamental science and real-world applications.
• Dario Gerace (University of Pavia): Believes this exotic state of light-based matter could transform photonic device technology.
