Quantum computing is finally starting to heat up. In addition to well-funded emerging companies and startups like QuEra, IonQ, Quantum Computing, Quantinuum, D-Wave, and Alice & Bob, there are also renowned and resource-rich tech giants like Google, Microsoft, Amazon Web Services, and NVIDIA, which are either building quantum processors (QPUs), simulating quantum processors, or integrating quantum processors with traditional supercomputers.
In the past year or so, many such companies have made significant progress in error correction, qubit count, and decoherence, scale, and quantum advantage, where quantum advantage refers to quantum computers being able to solve problems that classical computers cannot solve, or more practically, solve problems that would take classical computers years to complete, making that approach impractical.
Among the many quantum computing companies, IBM is undoubtedly the most noteworthy one. This tech giant with 114 years of history has been committed to the challenges of quantum computing for decades and has frequently made headlines in the past year. Notably, IBM unveiled its quantum computing roadmap in June this year (as shown below), aimed at integrating the various components needed to build Quantum Starling. Quantum Starling is a large-scale, fault-tolerant quantum system, and IBM executives stated that the system will be built in 2028 and put into use a year later through the quantum data center built by IBM in Poughkeepsie, New York.
