Harvard, Quera, Mit and Nist/University of Maryland are introducing a new era of quantum calculations by launching complex quantum algorithms on 48 logical cubits.
The leading developer of quantum computers using neutral atoms, Quera Computing, announced significant progress in the study and presented the results in the scientific journal Nature. In experiments carried out by Harvard University in close cooperation with Quer Computing, Mit and Nist/UMD, scientists successfully implemented large -scale algorithms on a quantum computer with 48 logical angles and hundreds of related logical operations. This significant breakthrough in quantum calculation meant the beginning of the development of really scalable and errors resistant quantum computers capable of solving virtually difficult classic problems.
Flatting errors is a key challenge for achieving efficient quantum calculation, requiring the use of quantum error correction for scale processing. However, the redundancy in the implementation of “logical” cubits, in which information is coded by many physical cubits to ensure reliability, creates serious challenges for scientists and researchers in creating quantum calculations on a scale.
Previous demonstrations of error correction showed one, two or three logical cubic. This new work shows the correction of quantum errors in 48 logical cubits, improving computing stability and reliability when solving the error problem.
Using control at logical level and using zone architecture in programmable neutral atoms, scientists combined two goals with high loyalty, random connections and fully programmable uniforms and medium chain reading. By launching this logical processor with different types of coding, they showed improvement of two -year logical gates by increasing the distance of the surface code, preparing the cubic color code with startward loyalty, impartial generation of GHz logical states and teleportation of a related connection and action of 40 code cubs. Using 3D code blocks, they implemented the compulsory sampling circuits with 48 logical cubs connected to hypercube connectivity with 228 logical gates of two squares and 48 logical CCZ gates.
Scientists have found that this logical coding significantly improves the efficiency of algorithmic errors detecting, exceeding the reliability of physical cubits in both inter -wing comparative simulations and rapid quantum entanglement. These results mean the beginning of the early quantum calculation era corrected by errors and indicate the way to large logical processors.
Achieving 48 logical cubits is an important milestone in the field of quantum calculations. This breakthrough not only accelerates the adoption of practical quantum applications, but also opens up new problems to solve problems, which were previously considered difficult using traditional calculation methods. It is a game changer and significantly increases the commercial importance of quantum calculations. Scientists suggest that enterprises and companies in various sectors should pay attention to this study, because the race for quantum advantage has gained a significant rush.
If subsequent experiments are equally effective, we can soon have scalable, damage resistant quantum calculations that could solve some of the most difficult problems in the world.
The future of quantum technology is here!
