Quantum computer is expected to come true: Stanford has developed a room temperature chip material

Lead researcher Elena Wakowik from the Stanford University Department of Electrical Engineering led the team recently published three papers in the magazine, claiming that they have developed quantum chip materials that can be operated at room temperature, including a quantum dot , Two kinds of "color center", so that the quantum processing device to take a big step forward to practical application.

It is understood that in the existing quantum computing technology, some cutting-edge research needs to cool the material to about zero degrees (-273.15 ℃), which hindered the quantum computer from theory to practical process. To solve this problem, scientists began to seek to replace traditional silicon-based computers with photon-based quantum computers. Quantum computers can perform a variety of complex computations faster, research biological systems, create encryption and big data systems, and solve many of the challenges involved with many variables.

Needle at sea: quantum computers are not afraid

As a leading scientist in the field of quantum computers, Wakowevik said: "When people think that one thing can not be done, they like to use" needle haystacks, "but quantum computing can do it." Quantum computers have Such a powerful capability lies in the complexity of the interaction between laser and electron on which it depends, which is the most crucial technique.

Quantum computers work by enclosing spintrons in a new type of semiconductor material. When laser light is applied to them, the laser interacts with the electrons to cause the electrons to assume different spin states. Conventional computers operate on binary systems with numbers 0 and 1; quantum computers operate on quantum bits. These qubits are superpositions of two states representing 0 and 1, and can be any number between 0 and 1. "In a quantum system, laser collisions with electrons create many possible spin states, and the more spin states, the more complex the quantum calculations that can be performed."

For nearly two decades, Wakomvik Lab has focused on the development of quantum chips that operate at room temperature. Recently, they worked with other labs to test three materials. As a result, one of the materials was fully capable of operating at room temperature. The quantum computer took a significant step forward, not just "talking on paper."
