China New Quantum Computer- Is It Superior to Google?

  • The Chinese developers claim that the new quantum computer takes close to 200 seconds to complete the calculations.
  • The quantum computers work by manipulating quantum objects, such as individual photons, electrons, or atoms.
  • Quantum technology has been expanding at the lightening speed.

The engineers from China announced the new work pertaining the new quantum computer Jiuzhang. The Chinese developers claim that the new quantum computer takes close to 200 seconds to complete the calculations. According to the published research, it is supposedly the fastest computer in the world.

China wants to claim the  quantum superiority. However, Chinese inventions have not been superior in the past. Therefore, it is premature to give China the leader title in the quantum technology.

Nevertheless, if it is true, the new quantum computer would be superior in comparison to the Google Sycamore computer. Sycamore is the name of Google’s quantum processor, comprising 54 qubits.

In 2019, Sycamore completed a task in 200 seconds that Google claimed, in a Nature paper, would take a state-of-the-art supercomputer 10,000 years to finish. Additionally, Google invests into the metal based superconducting qubits  vs Jiuzhang.

Furthermore, the quantum computer team was  led by Jian-Wei Peng at the laboratories of the University of Science and Technology of China.   The team from Shanghai was responsible for the  design and programming  the Jiuzhang photonic computer. The full work titled “Quantum computational advantage using photons” published here.

Moreover, the  quantum computers work by manipulating quantum objects, such as individual photons, electrons, or atoms, whilst utilizing the unique quantum properties. Quantum computers provide a large speed increase in comparison to the “classic” computers.

However, quantum technology has been expanding at lightening speed. Quantum technology is a class of technology that works by using the principles of quantum mechanics (the physics of sub-atomic particles), including quantum entanglement and quantum superposition. It should be noted, it is still very challenging to develop the full size quantum computer.

 

At present, the experiments that are being conducted show that some quantum objects are better suited to solving specific computational problems than others . Unprecedented computing power-qubits, photons qubits have unprecedented computing power due to their ability to exist in a double quantum state and therefore perform multiple calculations simultaneously.

Researchers expect that, armed with fairly stable qubits, quantum computers will shake up industries ranging from artificial intelligence to the myriad of industries and logistic chains. To note, qubits are difficult to scale.

According to the laws of quantum physics, photons seem to travel all possible paths simultaneously (superposition). The result of calculations can be recorded by measuring how many photons go to which output of the network.

There are challenges with the quantum computer technology. One of them is that photons have  strange quantum properties that complicate the development and impossible to predict which path they will choose.

Moreover, if two identical photons hit the beam splitter at the same time, they stick together and both move along the same randomly selected path. All this makes it very difficult for classical computers to identify patterns of photon behavior and predict the output configuration of photons based on how the particles were introduced.

It is highly likely, in this decade there will be full scale quantum computer made. Overall, the technology continues to evolve and the quantum has an important role.
