Supersolid Light: Scientists Reshape Quantum Matter with Photonic Breakthrough

Introduction

In a revolutionary leap for quantum science, researchers have successfully transformed light into a supersolid, a never-before-seen state of matter that fuses the rigid structure of solids with the frictionless flow of superfluids. This paradigm-shifting discovery, published in Nature on March 5, 2025, challenges the conventional understanding of light as a massless, intangible wave or particle—and redefines it as a quantum state with matter-like behavior.

Led by teams from CNR-INO, CNR-Nanotec, and the University of Pavia, this breakthrough opens exciting possibilities for quantum computing, energy storage, and next-generation photonic devices. It may pave the way for designing supersolid light-based systems that are more stable, coherent, and efficient than anything previously imagined in optical physics.

 What Is a Supersolid? Understanding This Exotic Quantum Phase

A supersolid is one of the most enigmatic phases of matter ever theorized. It possesses a rare duality that blends characteristics typically found in mutually exclusive states:

• Solid structure: Atoms or particles are arranged in a consistent, rigid crystalline lattice.
• Superfluid behavior: The material flows with zero viscosity, allowing frictionless movement.

This combination allows a supersolid to retain shape like a solid while flowing like a fluid, creating a dynamic material that behaves in extraordinary ways. Originally theorized decades ago, supersolids were mostly associated with ultra-cold atomic systems like Bose-Einstein condensates.

What sets this discovery apart is that scientists have now created a supersolid from light—an entity long thought to lack mass, structure, or the ability to behave like matter.

Turning Light into a Supersolid: How the Breakthrough Happened

Researchers at CNR-INO, CNR-Nanotec, and the University of Pavia achieved this feat by engineering a system that manipulates photons into behaving like quantum particles of matter. Here’s how the process unfolded:

 The Methodology

• Scientists used semiconductor nanostructures, specifically microcavities, to confine and control light.
• Inside these microcavities, photons interacted with excitons (bound electron-hole pairs), forming polaritons—hybrid light-matter quasiparticles.
• These polaritons condensed into quantum droplets that exhibited both ordered structure (like a solid) and frictionless flow (like a superfluid).

The result? A lattice of supersolid light droplets—coherent, stable, and mobile, behaving with properties never seen before in optical systems.

What Makes It Different

Previous experiments with supersolids relied on:

• Ultra-cold atoms
• Bose-Einstein condensates
• High vacuum and magneto-optical traps
