Beyond boundaries!Superconductors and semiconductors meet in shock, a new chapter in science and technology
When we enter the fantasy world of superconductivity, it is like entering a utopia with no resistance. Here, the current flows unimpeded, as if it is flying freely in a space without any resistance. It's a wonderful phenomenon that only superconductors can have, and once the temperature drops to near zero, the resistance disappears instantaneously, allowing the current to pass through unimpeded.
If superconductors are a universe without resistance, then semiconductors are like our electronic circuits in the real world. From mobile phones to TVs, to cars, to airplanes, to data centers, almost everything is tied to semiconductors. They are the "heart" of electronic products, injecting more intelligence and convenience into our lives.
The magic of quantum computers: the mystery between semiconductors and superconductivity.
You might never think that there is an even more mysterious connection between semiconductors and superconductivity: quantum computers. In the computers of the future, semiconductor chips will be used to manipulate qubits, just like wireless communication. It is precisely because of this technology that we can find the same laws in various fields, and then design a new technology according to the laws to change the world.
However, when designing qubits, it is difficult to do so. The technology requires operation in extremely low temperature environments, which presents unprecedented challenges to chip design. However, just as humanity's quest for technology never stops, we have made significant progress in this area. In this context, the "low-temperature superconducting quantum computer qubit control chip" independently developed by Tsinghua University came into being.
Prospects for the development of room-temperature superconductors and their effects.
Let's take another look at another kind of magic of superconductors. If we can achieve superconductivity, such as the superconductor of LK-99, at room temperature and apply it to qubits, it means a leap forward for superconducting quantum computers. This will greatly lower the threshold for quantum computing technology and provide more opportunities for more scientific research institutions. This is a rare opportunity. Due to the existence of room-temperature superconductors, existing quantum computers no longer need extremely low temperature refrigeration devices, which will greatly reduce the difficulty of manufacturing quantum computers.
Achieving superconductors at room temperature will have a profound impact on qubit chips. While the critical value of superconductivity can be lowered, the requirements for qubit-controlled chips are not. Since the fidelity of qubits and correlation processes has always been the main bottleneck restricting the development of quantum computing, the realization of qubit control chip performance is the key to achieving this goal.
