IBM demonstrates quantum advantage in a real-life scenario

Industry news

  • IBM claims to have demonstrated quantum advantage over classical computers in solving real-life problems, according to a research paper published in Nature Physics by the company on June 28, 2021. 

  • The experiment aimed to prove that quantum computers, even with noise (errors), could still offer more value than classical computers. A theoretical experiment on a noiseless quantum computer demonstrated 100% accuracy compared to 87.5% in a classical computer. Even when adjusting for noise, which is common in today's real-life quantum computers, the performance was better with 93% accuracy. 

  • It also disproved the "Holevo's boundary," which claims that one qubit can only store one bit of information. 

  • IBM has quantum processors ranging from 5-qubits to 65-qubits, and the company aims to develop a fully operational 1,000-qubit quantum computer that is 37 times faster by 2023. The company launched a quantum computer in Germany in June 2021 and is set to launch another in Japan in July 2021 to accelerate the development of real-life quantum applications.
