Quantum Advantage Emerges Over Classical Machines in Groundbreaking Sampling
A new benchmark for quantum computation has been set with the emergence of quantum advantage over classical machines in random circuit sampling (RCS). This groundbreaking achievement marks a significant milestone in the development of quantum computing, as it demonstrates the ability of quantum computers to solve complex problems exponentially faster than classical computers.
The Emergence of Quantum Advantage: A Historical Context
The concept of quantum advantage has been around for decades, but it wasn’t until 2019 that the first claim of quantum advantage was made by researchers at Google. They reported that their 53-qubit Sycamore processor had solved an RCS problem in just 200 seconds, a feat that would take the world’s most powerful classical supercomputers an estimated 10,000 years to accomplish.
However, this initial claim of quantum advantage was short-lived, as subsequent improvements to classical algorithms reduced the estimated time required to solve the problem to less than 15 seconds. This pattern has continued, with experimentalists pushing the boundaries of quantum computing forward, even as information theorists make quantum advantage harder to achieve by improving techniques used to simulate quantum algorithms on classical computers.
In recent years, researchers have continued to push the boundaries of quantum advantage, with claims of achieving quantum advantage in RCS problems. In October 2024, Google researchers announced that their 67-qubit Sycamore processor had solved an RCS problem that would take an estimated 3600 years for the Frontier supercomputer at the US’s Oak Ridge National Laboratory to complete.
The Zuchongzhi-3 Chip: A Breakthrough in Quantum Processing
The latest breakthrough in quantum advantage comes from researchers at the University of Science and Technology of China (USTC), who have developed a 105-qubit quantum processor called the Zuchongzhi-3. This processor has been designed to solve RCS problems with unprecedented speed and efficiency.
The Zuchongzhi-3 chip features 105 qubits and 182 couplers integrated on the same chip, allowing it to perform complex quantum computations with high fidelity. The design and architecture of the chip have been optimized to improve qubit coherence times and readout efficiency, making it possible to achieve quantum advantage in RCS problems.
The Zuchongzhi-3 chip is a significant breakthrough in quantum processing, as it demonstrates the ability to scale up quantum computing to larger numbers of qubits while maintaining high fidelity. This achievement paves the way for further advances in quantum computing, including the development of more complex quantum algorithms and applications.
Demonstrating Quantum Advantage in Random Circuit Sampling
Random circuit sampling (RCS) is a complex problem that has been used to benchmark the performance of quantum computers. In RCS, a quantum computer is tasked with sampling the output of a random quantum circuit, which is a complex problem that requires the manipulation of multiple qubits.
The Challenge of Random Circuit Sampling (RCS)
RCS is a challenging problem because it requires the ability to manipulate multiple qubits with high fidelity, while also maintaining control over the quantum circuit. Classical algorithms have been developed to simulate RCS, but they are limited by their computational resources and are unable to solve large-scale RCS problems efficiently.
Quantum computing, on the other hand, promises to solve RCS problems exponentially faster than classical computers. This is because quantum computers can manipulate multiple qubits simultaneously, allowing them to explore an exponentially large solution space in parallel.
The USTC Team’s Achievements: A New Benchmark for RCS
The USTC team has achieved a new benchmark for RCS by demonstrating the ability to solve large-scale RCS problems with high fidelity using the Zuchongzhi-3 processor. This achievement marks a significant milestone in the development of quantum computing, as it demonstrates the ability to achieve quantum advantage in a complex problem.
The Zuchongzhi-3 processor has been shown to be capable of solving RCS problems that would take billions of years for the world’s most powerful classical supercomputers to solve. This achievement has been made possible by the development of advanced quantum algorithms and the improvement of qubit coherence times and readout efficiency.
The USTC team’s achievement has set a new benchmark for quantum advantage in RCS, and it is expected to have significant implications for the development of quantum computing. The ability to solve complex problems exponentially faster than classical computers has the potential to revolutionize fields such as cryptography, optimization, and machine learning.
Implications and Future Directions
Quantum Error Correction: The Next Frontier
The importance of error correction in quantum computing cannot be overstated. As Xiaobu Zhu, a physicist at the University of Science and Technology of China (USTC), notes, “The requirements for error-correction readout are much more difficult than for RCS. RCS only needs one readout, whereas error-correction needs readout many times.”
The USTC team plans to demonstrate quantum error correction on Zuchongzhi 3.0, which will involve using an error correction code such as the surface code to combine multiple physical qubits into a single “logical qubit” that is robust to errors.
This achievement has significant implications for the development of quantum-resistant cryptography, as it would provide a means of encrypting and decrypting data that is resistant to quantum attacks.
The Potential Impact on Classical Computing
The role of quantum computing in solving complex problems is significant, as it has the potential to speed up calculations by orders of magnitude.
The potential for quantum-classical hybrid approaches is also significant, as it could allow classical computers to take advantage of quantum computing’s speed while still maintaining the reliability and fault tolerance of classical computing.
The implications for the future of artificial intelligence and machine learning are also significant, as quantum computing could provide a means of training and optimizing AI models faster and more efficiently than classical computers.

Quantum Computing’s Potential Impact on Industry and Society
Applications in fields like chemistry, materials science, and optimization are significant, as quantum computing could provide a means of simulating complex systems and optimizing processes more efficiently than classical computers.
The potential for quantum computing to revolutionize healthcare and finance is also significant, as it could provide a means of analyzing complex data sets and making predictions more accurately and efficiently than classical computers.
The need for further research and development to realize these prospects is significant, as the development of practical quantum computing applications will require significant advances in areas such as error correction, quantum control, and scaling.
