(ANSAmed) - MILAN, 16 AGO - A team of researchers
coordinated by Enrico Prati of the Institute for Photonics and
Nanotechnologies (IFN) at the Italian National Research Council
(CNR) in Milan developed a quantum computer that beats the
competition of Google, in a study published in the Nature
Research journal Communications Physics.
Applying artificial intelligence and deep learning to the
compiler opened the way for programming an algorithm that adapts
to any quantum computer based on logic gates.
The result was obtained with the collaboration of Matteo Paris
of the University of Milan and Marcello Restelli of Milan
Polytechnic.
"Similar to conventional computers, in which bits are subjected
to calculations through logic gates, in quantum computers it is
necessary to use quantum logic gates, which, however, must be
programmed by a sort of operating system that knows which
operations can be carried out," Prati said in the study.
"However, there are many different versions of hardware that
provide different achievable operations, like a small deck of
playing cards to choose from," he said.
Lorenzo Moro of CNR said the team therefore used deep learning
to develop a compiler able to find the right order "for playing
the five to six cards available, including with sequences
hundreds of plays long, choosing one by one the right ones to
form the entire sequence".
"After a training phase, which goes from a few hours to a couple
days, the artificial intelligence learns how to build new pieces
for every quantum logic gate, starting from the available
operations, but taking just a few milliseconds," he said.
The CNR Italy research has been patented.
"Our model surpasses a similar patent by Google, which uses
artificial intelligence after training but only for one logic
gate at a time, after which it needs a new training".
The researchers in this study discovered how to build all the
quantum logic gates with only one training, after which the
solution can immediately be recalled for any logic gate, in what
is known as deep learning.
Google recently inaugurated its Quantum AI Campus for the
development of quantum computers in Santa Barbara, California.
Eric Lucero, the lead engineer at Google Quantum AI, explained
at the inauguration how quantum computing will be necessary in
the coming years.
"Looking ahead 10 years, many of the biggest global challenges,
from climate change to the management of the next pandemic, will
require a new type of computing," he said. (ANSAmed).
