IBM Quantum Computers Show Superiority over Classic Supercomputers in Recent Experiment
Scientists from IBM Quantum, the University of California, Berkeley, and the National Laboratory of Lawrence Berkeley have demonstrated that a 127-cubic quantum computer can outperform classic supercomputers in specific calculations, showcasing a significant quantum breakthrough. The results of their study were published in the scientific journal Nature.
Addressing Vulnerability to Noise
During calculations, interference such as heat and vibrations can introduce errors. To combat this, IBM has developed a strategy called zero noise extrapolation (ZNE) to minimize errors. By controlling the noise within the quantum system and extrapolating the results back to evaluate the calculations without noise, IBM’s ZNE greatly reduces errors.
The Experimental Comparison
In an experiment conducted by IBM, the Quantum Eagle quantum computer went head to head with a traditional supercomputer. Despite the noise affecting the calculations, the quantum computer consistently produced accurate results that surpassed those of the classic supercomputer.
Future Prospects
The promising results of the experiment have inspired scientists to explore new methods for further enhancing both quantum and classic algorithms. IBM’s simulation of ZNE is an example of one such approach, with researchers aiming to determine if the concept of error reduction can be applied to classic tensor network simulations.
“Now we ask if we can apply this concept of reducing errors to classic tensor network simulations to see if we can get the best classic results,” said Sajant Anand, co-author of the study.
This breakthrough experiment demonstrates the potential usefulness of quantum computers in the modern world, even without extensive error correction. It also paves the way for studying quantum properties and developing new electronic materials.
