A new breakthrough described in a recent study published in Nature has opened the door to revolutionary developments in quantum technology. For the first time, researchers have both theoretically and experimentally demonstrated how superfluorescence—an exotic quantum state typically only seen at cryogenic temperatures—can be achieved at room temperature, thanks to the formation of so-called solitons in hybrid perovskite materials.

This advance could enable the development of quantum computers, sensors, and communication systems that do not require elaborate and expensive cooling systems. The research represents a major step toward realizing practical, scalable quantum technologies.

What Is Superfluorescence?

Superfluorescence is a type of macroscopic quantum coherence, a phenomenon in which particles act as a single giant quantum state. It's similar to how a school of fish moves in perfect sync or fireflies blink in unison. In quantum systems, this synchronization leads to unique properties like superconductivity, superfluidity, and superradiance.

But typically, achieving such coherence requires extremely low temperatures, since thermal noise disrupts the fragile synchronization of quantum particles. That limitation has been a major bottleneck in the deployment of quantum technologies outside the lab.

The Role of Hybrid Perovskites

In this groundbreaking study, a team led by Kenan Gundogdu of North Carolina State University uncovered the mechanism that protects quantum coherence at high temperatures in hybrid perovskite materials. These materials have been drawing attention for their photonic and electronic properties, especially in applications like solar cells and LEDs.

Earlier research suggested that the atomic lattice of certain hybrid perovskites could host large polarons—quasi-particles formed by electrons and the local deformation of the lattice—effectively shielding light-emitting dipoles from thermal noise. The new study goes a step further, showing that when the density of these polarons crosses a threshold, they self-organize into solitons: coherent, ordered quantum structures that suppress thermal disturbances and allow room-temperature quantum effects to emerge.

Visualizing the Soliton Mechanism

Imagine a stretched fabric (the atomic lattice) with small balls (excitons) placed on it. Each ball creates a dip in the fabric. Under the right conditions, these dips align to form a wave-like structure—a soliton—that moves as a unified entity. This process was directly observed and measured in the lab, marking one of the first experimental verifications of room-temperature macroscopic quantum state formation.

Implications for High-Temperature Quantum Devices

The ability to achieve superfluorescence at room temperature represents a major paradigm shift. According to the study, this mechanism could guide the development of new quantum materials and devices that function in everyday conditions, without the need for costly cryogenics.

"Now that we understand the underlying physics, we can engineer materials specifically tailored to maintain coherence at high temperatures," said Gundogdu. This paves the way for innovations in:

  • Quantum Computing: Enabling error-resistant qubits operating at ambient conditions.
  • Quantum Communication: Facilitating entanglement and secure transmission without refrigeration.
  • Quantum Sensing: Allowing ultrasensitive detectors for medical imaging, navigation, and more.

Collaboration and Simulation

The study brought together experts from NC State, Duke University, Boston University, and the Institut Polytechnique de Paris. Theoretical work by Mustafa Türe and experimental validation by Melike Biliroglu were instrumental, supported by quantum simulations from Volker Blum (Duke) and Vasily Temnov (CNRS, École Polytechnique).

A Blueprint for the Future

This work not only describes a new phenomenon but provides a quantitative theory and replicable methodology. It suggests that with the right perovskite structures and excitation conditions, solitonic superfluorescence could become a foundational feature of next-generation quantum devices.

According to Franky So, another co-author from NC State, “Prior to this work it wasn’t clear if there was a mechanism behind high-temperature quantum effects in these materials. Now we have that clarity.”

Quantum Chemistry Meets AI: A New Era for Molecular Machine Learning

Image
In a powerful leap forward for computational chemistry and materials design, researchers from Carnegie Mellon University have developed a new kind of molecular machine learning model—one that goes beyond simplistic molecular graphs and integrates fundamental principles of quantum chemistry. Their work, published in Nature Machine Intelligence , could radically enhance our ability to predict chemical behavior, optimize catalysts, and discover new drugs, all while using less data and gaining more scientific insight. The Problem: Traditional Molecular Representations Fall Short Molecular machine learning (ML) models underpin key processes in drug discovery, materials science, and catalysis. However, most existing models use simplified representations such as SMILES strings, 2D graphs, or coordinate matrices. These techniques often lack the quantum-chemical information that governs how molecules truly behave—particularly electron interactions that define reactivity, stability, and...
