Russian researchers have created an Artificial Intelligence (AI)-based tool that has learned to predict the behaviour of a quantum system by “looking” at its network structure.

The neural network autonomously finds solutions that are well-adapted toward quantum advantage demonstrations, according to a study published in the New Journal of Physics.


This is expeted to aid researchers in developing new efficient quantum computers.

“We have been quite successful in training the computer to make autonomous predictions of whether a complex network has a quantum advantage,” said Leonid Fedichkin, Associate Professor at the Moscow Institute of Physics and Technology (MIPT).


What the Russian researchers did is they replaced the experts with AI. They trained the machine to distinguish between networks and tell if a given network will deliver quantum advantage. Pixabay

A wide range of problems in modern science are solved through quantum mechanical calculations.

Some of the examples are research into chemical reactions and the search for stable molecular structures for medicine, pharmaceutics, and other industries.

The quantum nature of the problems involved makes quantum computations better-suited to them. Classical computations, by contrast, tend to return only bulky approximate solutions.

Creating quantum computers is costly and time-consuming, and the resulting devices are not guaranteed to exhibit any quantum advantage – that is, operate faster than a conventional computer.

So researchers need tools for predicting whether a given quantum device will have a quantum advantage.

One of the ways to implement quantum computations is quantum walks. In simplified terms, the method can be visualised as a particle travelling in a certain network, which underlies a quantum circuit.

If a particle’s quantum walk from one network node to another happens faster than its classical analogue, a device based on that circuit will have a quantum advantage.

The search for such superior networks is an important task tackled by quantum walk experts.

What the Russian researchers did is they replaced the experts with AI. They trained the machine to distinguish between networks and tell if a given network will deliver quantum advantage. This pinpoints the networks that are good candidates for building a quantum computer.

The team used a neural network geared toward image recognition. An adjacency matrix served as the input data, along with the numbers of the input and output nodes. The neural network returned a prediction of whether the classical or the quantum walk between the given nodes would be faster.

“It was not obvious this approach would work, but it did,” Fedichkin said.

“The line between quantum and classical behaviours is often blurred. The distinctive feature of our study is the resulting special-purpose computer vision, capable of discerning this fine line in the network space,” added Alexey Melnikov from ITMO University in Russia.

The researchers created a tool that simplifies the development of computational circuits based on quantum algorithms. The resulting devices will be of interest in biophotonics research and materials science. (IANS)

As per the man, his wife had developed an illicit relationship with a man, living nearby their house. | Unsplash

High drama was witnessed in Kanpur Dehat for over an hour when a man, upset over his wife's alleged affair with a local man, climbed the tower with his children and threatened to commit suicide. The incident took place on Monday near Gandhi Nagar in Akbarpur, when the man threatened to commit suicide after throwing his kids down from a height of nearly 40-feet. Chaos prevailed around the area and the locals informed the police that rushed to the spot.

After about half-an-hour of convincing, the police managed to bring him and his children down. The man told the police that his wife's affair was going on with his neighbor. He had complained to the police, but no action was taken. Police said that as per the man, his wife had developed an illicit relationship with a man, living nearby their house. "As per the man, in his absence, his neighbor visited his house often. He said that he had reprimanded his neighbor many times, but to no avail," said the police.

The US forces continued their bombardment of buildings and institutions in Syria's northeastern Hasakah province, as part of their alleged manhunt of Islamic State (IS) fugitives, state news agency SANA reported. The US forces are shelling buildings and public institutions on Tuesday in the vicinity of the Sina'a prison in the Gweiran neighborhood in Hasakah "on the pretext of hunting down IS militants who fled the prison," said SANA.

Multiple avian influenza outbreaks have occurred in India, the UK, the Netherlands and Israel. | Unsplash

The circulating avian influenza outbreaks, including in India, do not seem to pose the 'high' risk but surveillance and biosecurity measures are necessary to reduce spillover risk between poultry and wild birds, a UN-backed scientific task force said. Throughout the past autumn and current winter in the northern hemisphere, multiple avian influenza outbreaks, caused predominantly by the H5N1 HPAI virus, plus other subtypes, including H5N8, have occurred in India, the UK, the Netherlands and Israel with the ever recorded mortality of the Svalbard barnacle geese in Solway Coast.
