IBM has unveiled its plans to build Starling, the world’s first fault-tolerant quantum computer, by 2029. The company claims to have overcome the major hurdle in quantum computing, paving the way for a machine that will be 20,000 times more powerful than current quantum computers. In a recent breakthrough, IBM researchers introduced new error-correction techniques that allow for a more efficient scaling of quantum hardware.
The upcoming quantum computer, named Starling, will feature 200 logical qubits and around 10,000 physical qubits. Following Starling, IBM aims to launch Blue Jay in 2033, a machine with 2,000 logical qubits. This advancement signifies a significant leap in quantum computing capabilities, with experts stating that the science behind fault-tolerant quantum computing has been successfully addressed.
Quantum computers today are limited in their performance compared to classical systems, primarily due to errors in quantum calculations. These errors compound as more qubits are added to processors, necessitating advancements in quantum error correction. IBM’s novel quantum low-density parity check (LDPC) codes offer a solution to this challenge, enabling a more efficient scaling of quantum systems.
The LDPC codes utilize error detection and correction mechanisms to enhance the reliability of quantum computations. By reducing the number of physical qubits required for error mitigation, IBM’s approach aims to significantly improve the encoding rate of logical qubits. This breakthrough is projected to make error correction processes about 90% faster than existing techniques, marking a critical milestone in quantum computing development.
Starling is anticipated to perform 100 million quantum operations using 200 logical qubits, equivalent to 10,000 physical qubits. Blue Jay, on the other hand, is expected to handle 1 billion quantum operations with its 2,000 logical qubits. These advancements underscore the potential of IBM’s quantum computing technology to revolutionize computation capabilities in the near future.
To fully leverage the capabilities of Starling and Blue Jay, IBM emphasizes the need for quantum algorithms and software tailored for these systems. The company recently introduced Qiskit 2.0, an open-source development kit designed to facilitate the execution of quantum circuits on IBM’s hardware, aiming to empower researchers in harnessing the power of quantum computing tools.
IBM’s progress in quantum computing signifies a significant step towards achieving fault-tolerant quantum systems. By addressing key challenges in error correction and scalability, the company is poised to usher in a new era of quantum computing capabilities that could revolutionize various industries and scientific disciplines.
