China has made a breakthrough
in the research of quantum computing.
The quantum laboratory of the University
of Science and Technology of China recently
announced its success in developing a
semiconductor quantum chip.
According to a CNTV
report on Aug. 11, the quantum chip is
equivalent to the "brain" of future
quantum computers; it enables quantum operations
and information processing. Besides computing,
technologies for quantum storage and control
are also essential to the future of
this technology. The "sandwich-type" solid-state
quantum memory can be operational at a
low temperature with magnetic auxiliary equipment.
Zhou Zongquan, a researcher
at the Key Laboratory of Quantum Information
under the Chinese Academy of Sciences
(CAS), said that the direction of future
development is to prolong the life of
quantum memory.
"Ultimately we hope
to fit it into a classic, portable
USB in order to achieve the long-distance
transmission of quantum information," Zhou
said.
Quantum computers are
expected to overtake existing computers in
both speed and performance. The quantum
chip is the core element that distinguishes
a quantum computer from an ordinary one.
At present, many foreign research institutions
have begun research in this field, and
China remains at the forefront.
According to Guo Guangcan,
an academician with CAS, quantum computers
constitute disruptive technology. Once the technology
is successfully developed, it will be
able to crack passwords and solve various
problems related to big data. Currently,
quantum technology is still in the experimental
stage. There is a long way to go
before commercialization.
