Wedoany.com Report on Feb 11th, The core challenge in quantum computing lies in the scalable expansion of qubits, with their fragility and susceptibility to noise interference limiting system stability. Recently, research from Columbia University in the United States has provided a new path for qubit scaling by combining laser technology with surface encoding.

As the fundamental unit of quantum computing, the scalable expansion of qubits requires overcoming the problem of physical qubits being easily disturbed by noise. Traditional methods have had limited success in simultaneously expanding the number of both physical and logical qubits. The research team employed metasurface optical tweezer array technology, using a two-dimensional array composed of nanoscale pixels to reshape the light beam, successfully capturing 1000 strontium atoms capable of functioning as qubits, with plans to scale up to one hundred thousand atoms.
This laser-based metasurface technology can achieve consistency across the entire atomic ensemble, enhancing the stability of the qubit array. This breakthrough provides a new perspective for the scalability of quantum computing and may advance research areas such as quantum teleportation. Laser technology played a crucial role in this process, becoming an important tool for manipulating microscopic particles.
The connection between quantum computing and laser technology is becoming increasingly close. Last November, TRUMPF, in collaboration with the Fraunhofer Institute for Laser Technology and the Free University of Berlin, launched a project to study laser physics using quantum algorithms. The project aims to simulate quantum processes inside lasers using quantum computers, accelerating the development of semiconductor lasers and CO2 lasers, and laying the groundwork for industrial applications.
Although quantum computers are not yet capable of handling complex industrial simulation tasks, such research helps accumulate specialized knowledge and prepares for future technological applications. The synergistic development of laser technology and quantum computing is propelling both fields towards practical breakthroughs.
