Researchers Demonstrate Quantum Computing's Abilities in Chemistry
Cleveland Clinic

Kenneth Merz, PhD, of Cleveland Clinic's Center for Computational Life Sciences, and a research team are testing quantum computing’s abilities in chemistry through integrating machine learning and quantum circuits. Chemistry is one of the areas where quantum computing shows the most potential because of the technology’s ability to predict an unlimited number of possible outcomes. To determine quantum computing's ability to perform complex chemical calculations, Dr. Merz and Hongni Jin, PhD, decided to test its ability to simulate proton affinity, a fundamental chemical process that is critical to life. Dr. Merz and Dr. Jin focused on using machine learning applications on quantum hardware. This is a critical advantage over other quantum research which relies on simulators to mimic a quantum computer’s abilities. In this study, published in the Journal of Chemical Theory and Computation, the team was able to demonstrate the capabilities of quantum machine learning by creating a

Scientists Merge Two “Impossible” Materials Into New Artificial Structure
Rutgers University-New Brunswick

An international team led by Rutgers University-New Brunswick researchers has merged two lab-synthesized materials into a synthetic quantum structure once thought impossible to exist and produced an exotic structure expected to provide insights that could lead to new materials at the core of quantum computing. The work, described in a cover story in the journal Nano Letters, explains how four years of continuous experimentation led to a novel method to design and build a unique, tiny sandwich composed of distinct atomic layers.

Universal Conservation Laws of the Wave–Particle–Entanglement Triad
Chinese Academy of Sciences

Wave-particle duality and entanglement are cornerstone concepts in quantum physics, yet their exact relationship has long remained a mystery. Researchers from China and Singapore have forged a theoretical framework that unifies wave-particle behaviours with entanglement. By introducing conservation laws that bridge these quantum phenomena, they unveiled deep connections between them. These predictions were experimentally verified using silicon-integrated nanophotonic quantum chips, offering transformative insights into the fundamental principles of quantum mechanics.

Quasi-particles are collective quantum elements of condensed matter. They are foundationally important for understanding physics of materials and for technological applications of semiconductors. Using ultrafast optical pump-probe technique, scientists discovered a series of new spectral features that are not attributable to existing quasi-particles. By using advanced quantum many-body theories, these spectral features could be uniquely explained by the existence of a new quasi-particle called quadruplon, a genuine four-body composite particle, different from the known bi-exciton.

Simulations of equations from the Standard Model of particle physics are too difficult for classical supercomputers. In this research, scientists for the first time created scalable quantum circuits to prepare a simulation of the starting state for a particle accelerator collision to test aspects of strong interactions. The researchers first determined these circuits for small systems using classical computers, then scaled the quantum circuits to a large system on more than 100 qubits of IBM’s quantum computers.

Simulations of quantum many-body problems are a challenge for even the most powerful conventional computers. Quantum computing has the potential to solve this challenge using an approach called an analog quantum simulation. To succeed, these simulations need theoretical approximations of how quantum computers represent many-body systems. In this research, nuclear physicists developed a new framework to analyze these approximations and minimize their effects.
