Quantum computing is an emerging technology that will take conventional computing to a new level with its powerful processors.
In a landmark study, researchers at the University of Science and Technology of China in Hefei have demonstrated artificial intelligence on a quantum computer, reported the blog The Physics arXiv.
The computer scientists used machine learning, a process where an algorithm learns from existing sets of data, to train the computer. The researchers trained the computer to recognize the difference between a handwritten 6 and a handwritten 9.
With machine learning, they taught the algorithm to convert each image into a vector by analyzing the number of image pixels in each part of the picture.
Their quantum computer could recognize handwritten characters, similar to humans.
"This is the first demonstration of quantum artificial intelligence," said Zhaokai Li, a physicist and computer scientist who led the project.
The increased power in quantum computing is derived from superposition, a phenomenon where a quantum object can exist in two states at the same time.
Using binary code, one of those states represents a 1 and the other a 0, forming a quantum bit or qubit.
A qubit, using an atomic nucleus as an example, can perform a calculation on two numbers at the same time. The more nuclei, the more powerful is the computer.
"Two nuclei can handle 4 numbers, 3 nuclei 8 numbers and 20 nuclei can perform a calculation using more than a million numbers simultaneously," according to The Physics arXiv.
In this experiment, the quantum computing machine is made of organic liquid carbon-13-iodotrifluroethylene, a molecule consisting of two carbon atoms attached to three fluorine atoms and one iodine atom. One of the carbon atoms is a carbon-13 isotope.
Each of the three fluorine atoms and the carbon-13 atom can store a single qubit.
This experiment is a big leap for quantum computation, not only for character recognition, but for potential applications of Big Data and data analytics.
"The successful classification of characters shows the ability of our quantum machine to learn and work like an intelligent human," said Li. "This work paves the way to a bright future where the Big Data is processed efficiently in a parallel way provided by quantum mechanics."
Researchers in the field are attempting to build more powerful quantum computers. This task will require devices that can an increased number of qubits.
