Introduction to Quantum Computing

A quantum computer is a physical device that follows the laws of quantum mechanics, performs high-speed calculations, stores and processes quantum information. Because it uses overlapping qubits (also known as qubits), 0 and 1 can appear “simultaneously” when processing data, completely subverting the existing principles of computer operations and inherent limitations. Therefore, its advantages are also very obvious: the processing speed is amazing, billions of times faster than traditional computers (note: the explanations in this article are just basic concepts, the real technology involved in quantum computers is much more profound than this).

Extremely difficult to make, let alone commercialization

We must take into account various commercially available and useful features such as ease of control and ensuring state maintenance and durability, in order to create a truly practical volume computing solution. Many companies claim to have found a way to manufacture large quantities of solid-state quantities, that is, Transmon manufacturing technology. Because this technology is similar to the existing chip manufacturing technology, many major players in the market (including Alphabet, International Business Machines’ Rigetti) chose to use Transmon technology; however, it is not easy to maintain the state because it needs to be controlled in an ultra-low temperature state. Transmon technology requires a complicated dilution refrigeration system, but another trapped-ion technology only requires liquid helium refrigeration.

The main obstacle at this moment

According to Intel, the current development of quantitative computing still encounters the following major obstacles to be overcome:

  • The measurement bit error correction method ensures that the measurement bit has a sufficient life span, and the life span must be long enough that it can complete some meaningful calculations. This is like the artificial solar fusion. The fusion must be found to have a long enough lifespan and can be controlled by humans before commercialization is possible.
  • Need the local control of the measurement of qubit, rather than through the remote connection to control.
  • The arrangement on the path, that is, how to put the measurement qubit into a physical measurement bit system.
  • The connection between the measurement qubits is to connect the measurement qubits to form a relatively large-scale system.

Participating vendors

At present, the major commercial quantum computer manufacturers in the world are in North America. Their progress, respective development, and milestones reached are as follows:

Where is its value?

Quantitative calculations can solve many problems that cannot be solved by conventional calculations in the past, such as material simulation, pharmaceutical simulation, and encryption algorithms in the post-quantity era. The most optimistic estimate is that it will take at least 10 years before the actual commercial use of mass calculations can be achieved. Even if it enters the commercial phase – that is to say, most of the existing algorithms are still It is still valid and will not make traditional calculation methods, such as deep learning, artificial intelligence, obsolete. For your information you can refer to my previous blog post “Artificial intelligence investment trap

It seems that measuring computers can definitely subvert the existing calculation methods that have been used for decades. Even the most recent supercomputers are just pediatrics in front of them. However, I would like to remind investors that, like supercomputers, measurement computers are very expensive, have limited uses, and have a small market – they will not be good investment targets. Otherwise, the world’s most famous Cray Inc. supercomputer company would not go bankrupt, because people who can afford it are very rare. In Taiwan, apart from unverifiable intelligence units, there is only the Central Meteorological Bureau.
