Natural Evolutionary Strategy: A Quantum Leap in Computing Performance

In recent years, quantum computing has been at the forefront of technological advancements, promising to revolutionize industries from healthcare to finance. The latest breakthrough in this domain comes from an unexpected source: nature. Researchers have discovered that a natural evolutionary strategy can significantly enhance the performance of quantum computers.

A Novel Approach to Quantum Computing

Researchers from Intelligent Computing have recently unveiled a groundbreaking method that employs a natural evolutionary strategy to boost the performance of quantum computers. This innovative approach, known as NESAdaBelief, optimizes Variational Quantum Algorithms (VQAs). The strategy focuses on the calculation of quantum parameters, ensuring that these algorithms operate at their peak efficiency.

The Science Behind the Strategy

Natural evolutionary strategies (NES) are not new to the world of algorithms. They belong to a family of gradient-free black-box optimization algorithms. However, their application in the realm of quantum computing is a pioneering effort. The primary focus of this study was the optimization of randomly initialized parameterized quantum circuits (PQCs), especially in areas with vanishing gradients.

Two specific methods were implemented in this research:

  1. NESSGD (Natural Evolutionary Strategy Stochastic Gradient Descent): This method focuses on the natural evolutionary strategy combined with stochastic gradient descent to optimize the values of PQC parameters.
  2. NESAdaBelief: This method adapts the step size according to the belief in observed gradients, ensuring the optimization of PQC parameter values.

Implications for the Future

The implications of this research are vast. By harnessing the power of natural evolutionary strategies, quantum computers can achieve unparalleled performance levels. This not only accelerates the computational capabilities of these machines but also opens up new avenues for applications in various sectors.

Moreover, the team led by Yumin Dong of Chongqing Normal University has emphasized the significance of optimizing parametric quantum circuits. These circuits are a crucial component of variational quantum algorithms, and their optimization can lead to more efficient and accurate quantum computations.
