Quantum computers have the potential to outperform our fastest classical computers in specific areas, according to a recent study conducted by Google Quantum AI researchers. The study revealed that quantum computers can achieve a “stable computationally complex phase” with existing quantum processing units (QPUs), allowing them to perform calculations that surpass the capabilities of even the fastest supercomputers.
The research, led by quantum computing researcher Alexis Morvan, was published in the journal Nature. Google Quantum AI representatives emphasized the importance of developing practical applications for quantum computers that are beyond the capabilities of classical computers. The ultimate goal is to demonstrate a “beyond classical” application with real-world impact.
While quantum computers show promise, they still face challenges related to noise in the data they produce. Quantum computers rely on qubits, which operate based on the principles of quantum mechanics and can perform calculations in parallel. The more qubits a quantum computer has, the more powerful it becomes exponentially. However, qubits are sensitive to interference and prone to failure, requiring sophisticated error-correction technologies to maintain their performance.
Despite these challenges, the recent experiment conducted by Google scientists demonstrated that quantum computers can outperform classical computers in specific calculations even in the presence of noise. The experiment involved testing the fidelity of a 2D grid of superconducting qubits using a method called random circuit sampling (RCS). The results showed that working qubits could transition to a “weak noise phase,” where they could outperform classical computers in complex computations.
This breakthrough is a significant step towards realizing the full potential of quantum computers and developing applications that are beyond the capabilities of classical computers. As quantum computing continues to advance, researchers are optimistic about the possibilities it holds for the future of technology and innovation.
