Quantum processor exploring exotic phases of matter

In a landmark achievement, physicists from the Technical University of Munich (TUM), Princeton University, and Google Quantum AI have demonstrated a new exotic phase of matter using a 58-qubit superconducting quantum processor. Published in Nature, the research confirms that quantum computers are not just computational devices but also powerful laboratories for probing new states of matter (Phys.org article).

Beyond Equilibrium: A New Playground for Matter

We’re all familiar with the classic phases of matter—solids, liquids, gases, and plasmas. These conventional states exist under equilibrium conditions. But in nonequilibrium regimes, driven by time-dependent forces, entirely new phases can emerge. These are called nonequilibrium quantum phases, and they defy the rules of classical thermodynamics.

A particularly rich family of such states appears in Floquet systems, where quantum systems are rhythmically driven in time. In this study, researchers realized a Floquet topologically ordered state, a theoretically predicted phase that had never been observed experimentally—until now.

How the Quantum Processor Revealed an Exotic Phase

The team used their 58-qubit quantum chip to simulate and probe this exotic state. They directly imaged the directed edge motions characteristic of topological order and applied a novel interferometric algorithm to measure the system’s hidden topological properties. In doing so, they observed the dynamical transmutation of exotic particles—a phenomenon predicted in theory but never before seen in practice.

“Our results show that quantum processors are not just computational devices—they are experimental platforms for discovering and probing entirely new states of matter.” – Melissa Will, Ph.D. student, TUM

Implications for Quantum Physics and Technology

This discovery represents a major step forward in using quantum computers as quantum simulators. Classical computers struggle to simulate highly entangled nonequilibrium phases, but quantum processors can natively explore this vast and largely uncharted landscape.

The implications extend from fundamental physics—deepening our understanding of quantum many-body systems—to quantum technology. Insights gained could eventually aid in developing more robust quantum error correction, new types of quantum materials, and advanced quantum devices that leverage exotic properties of matter.

Quantum Computers as Discovery Engines

This work reinforces the idea that quantum processors are not merely tools for computation but platforms of discovery. Much like particle accelerators unlocked the physics of the subatomic world, quantum computers may become indispensable in exploring exotic and emergent quantum phenomena.

As research expands, quantum processors could help us design next-generation technologies—from materials with novel electronic properties to scalable architectures for quantum computing itself.

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...

Water Simulations Under Scrutiny: Researchers Confirm Methodological Errors

Image
Accurate water simulations are vital for research in biomolecular structures, drug discovery, and materials science. But a recent study from Oak Ridge National Laboratory (ORNL) has revealed a potential pitfall in long-standing computational methods, raising concerns about the reliability of countless molecular dynamics studies. The Time Step Problem in Simulations At the heart of the issue is the “time step” used in simulations—the small intervals at which calculations are performed. Since the 1970s, scientists have used time steps of 2 femtoseconds (quadrillionths of a second) to simulate molecular motion efficiently. However, the ORNL team has shown that using this standard can introduce significant errors when modeling liquid water, potentially leading to inaccurate predictions of properties such as density, pressure, and hydration energies. “Using longer time steps is tempting because it reduces computational cost,” explained senior scientist Dilip Asthagiri. “But a...

CrystalGPT: Redefining Crystal Design with AI-Driven Predictions

Image
July 18, 2025 In a major leap for materials chemistry, researchers in the UK have developed Molecular Crystal Representation from Transformers (MCRT) —an AI model likened to ChatGPT for its transformative impact. Dubbed "CrystalGPT" , this foundation model rapidly predicts the physical properties of molecular crystals, revolutionizing how chemists design materials in silico . The AI Revolution in Crystal Design Understanding and predicting the properties of molecular crystals is critical for designing new materials for applications ranging from pharmaceuticals to energy storage. Traditional computational approaches, though powerful, are often resource-intensive and slow. Machine learning methods such as Smooth Overlap of Atomic Positions (SOAP) and atom-centred symmetry functions (ACSFs) have offered improvements, but they struggle with large datasets and subtle structural nuances. CrystalGPT, developed by a team led by Andy Cooper at the University of Liverpool, o...
