The quantum computer named STARLING will be built by a leading company, IBM, with the help of 200 logical qubits up to the year 2029, and IMB set a plan to extend it to 2000 logical qubit machines in 2033 as their future vision. According to IBM scientists, they have cracked the biggest challenge in quantum computing which is quantum decoherence. Due to the interaction of qubits with environments, they lose their quantum state, which leads to error. Thus, a robust quantum computer requires a highly fault-tolerant infrastructure. 

New research shows an error-correction method which, according to the scientist's prediction, will hold the potential to build a quantum system 20,000 times more powerful in terms of quick and precise calculations and results than any existing quantum computer to date. As per new studies published on the preprint arXiv server, scientists have found new error-reduction and correction techniques that can handle these errors while offering nine times more scaling for hardware more efficiently than before. 

The system will be made up of roughly 10,000 physical qubits, and this will be achieved by the ‘Blue Jay’ machine, which will use nearly 2000 logical qubits in 2033. The new research has not yet been reviewed by other scientists and professionals within this sector, which is known as a novel fault-tolerance paradigm, and it shows IBM’s quantum low-density parity-check codes that will help researchers to scale quantum computer hardware way beyond what was previously done. 

The vice president of IBM, Mr. Jay Gambetta, who is currently working on quantum operations, stated to the media that, “The science has been solved” for expanded fault-tolerant quantum computing. To build a highly scalable quantum computer is merely an engineering barrier instead of the theoretical hurdle of quantum science. 

Error correction is a basic barrier to achieving quantum supremacy. Quantum calculations are more susceptible to errors than classical computer calculations as they require a highly controlled temperature to save a qubit from environmental interaction, leading to quantum decompression. However, the development of LPDC and its application within the established systems act as a catalyst for the transformation in quantum computing. The LPDC code system utilizes a set of checks to find errors and correct them, which will potentially enhance the “encoding rate”- a ratio of logical qubits to the physical qubits required to protect them.
