High -felt confused door remote super conducting quantum processors connect

Quantum computers are capable of solving some correction and data processing problems that cannot be dealt with by classical computers. Many intelligent quantum computing platforms so far are based on super -conducting quat, small circuits based on super conducting materials.

Despite their good performance, most super -conducting quantum processors still show important limits that prevent their high and deployment. These include the frequency crowds (ie, interference between multiple quaties with overlaping resonance frequency) and many cobs -related controls or measurements.

To overcome these boundaries, some physicists and engineers are searching for the possibility of understanding distributed quantum computing, including contacts between several small processors that act as a large system. This will require the establishment of so -called confused doors, instructions that work on two or more causes simultaneously and link them through a quantum mechanical effect known as confusion.

Researchers from the Beijing Academy of Quantum Information Sciences and the Chinese Academy of Sciences recently presented a new approach to creating a high -minded gates between two remote super -conducting quantum processors. In a recent article, which appeared Physical review postsHe reported the cognition of the highly sincere gates between the two processors, which was 30 cm away.

“The work began last year with a question posed by Dr. Fei Yan (one of the co -authors),” said Wen Gang Zhang, co -author of the article, told Faz. Rag. “He asked, ‘Can we realize the two cobbut -confused gate between two remote quantum chips?’

“As stated in the dissertation, remote contacts between quantum chips have been demonstrated. However, these enforcement have always been dependent on quantum state transfer (QST), which is not suitable for the circuit -based quantum computing.

The main purpose of the team’s recent study was to remove the boundaries of the QST -based approach to understand the doors that confused the remote quantum chips. In particular, researchers managed to realize the two -wide coat -confused doors, known as CNOT and CZ.

Zhang explained, “We felt the two cobbut -confused doors (the perfect antingler) that the cross -echo effects use the effect.” “This effect is widely used to understand the gates between super -conducting cobs on the same chip. In these tasks, they are combined with cobs capsators.

As part of their study, researchers discovered the possibility of using microwave cables in the couple’s remote cubs. Subsequently, they took advantage of an effect known as the ‘Cross Impact’ to understand the enthusiasm of their desired doors.

Zhang said, “This task shows the first direct two cobat gate between different quantum chips with such high loyalty.” “In particular, the protocol is a significant easy to put into practice, which does not require extra quet or control lines. We believe it will be a major building block for distributed quantum computing.”

This recent work of Jong and his colleagues can soon open new prospects for the universal and distributed quantum information processing. In the future, the methods used as part of this study can also be used for a couple in the same quantum chip, which also enables quantum LDPC error correction codes (ie quantum computers to detect and correct errors).

Zhang added, “So far, we realized a simple demonstration of two cobbut -confused gates between two remote chips.” “In the future, we plan to prepare some big chips that have ~ 100 cubits and are confused to achieve the purpose of distributed quantum computing. Also, the microwave cable is closed on the chip. We want to plug and play it so that we can remove one of the chips.”
