[US•China Competition, Japan also chase… ‘Key of forth Industry’ Life and Death of Quantum Computer Development]


In order to preoccupy the fourth industry, such as autonomous driving and artificial intelligence, countries around the world are putting their lives to the competition for quantum computer development.

A quantum computer can complete operations that take 100 years for a supercomputer in hundreds of seconds. The United States and China are leading the way, and Japan is chasing fast, but Korea is still in early stages.

Reporter Seoyoung Son covered it.



The world’s first commercially available quantum computer that looks like a chandelier. Colorful pure gold parts are mounted inside the circular column. It works only at cryogenic temperatures, minus 273.15 degrees with zero electrical resistance.

Unlike ordinary computers that operate on ‘bit’ units, which are combinations of zeros or ones, quantum computers use states of 0 and 1 that overlap or become entangled.

Storage and processing capacity become up to trillions of times. It can complete operations that take 100 years for a today’s most powerful supercomputer in hundreds of seconds. When the quantum computer is put into practical use, it is possible to process large amounts of data quickly, which can greatly develop the fourth industry such as autonomous driving.

In particular, the world’s focus on quantum computers is their ability to solve complex cryptosystems.

US and China are also fiercely competing for a security using quantum computers. Japan, which has been intensively investing since the ’80s, is also closely following.

[June-Koo Kevin Rhee/Professor of KAIST School of Electrical Engineering : The fact that it can break the cryptosystem has led to a lot of investment in quantum computers, while these concerns have led to the development of new cryptosystems.“]

However, Korea still lags far behind Japan in new concept computing technologies such as quantum computers. The quantum industry market continues to grow, and by 2035 it is expected to reach 400 trillion won, close to the current semiconductor market.
