International Business Machines (IBM) plans to have a practical quantum computer by 2029.
IBM also stated its goal of having a much larger system by 2033, planning to build the quantum computer "Starling" in a data center under construction in Poughkeepsie, New York, and claimed it will have about 200 logical qubits.
Qubits are the fundamental unit of quantum computing, and 200 qubits would be enough to begin showing advantages over classical computers (the current ones).
IBM is not the only company pursuing quantum computing; we also have Microsoft (MSFT), Google's parent company, Alphabet (GOOGL), Amazon (AMZN), and other companies that have been developing the next advancements in this industry, which is expected to be the next major technological breakthrough.
Quantum computers leverage quantum mechanics to solve problems that classical computers (current ones) would take thousands of years or more to solve.
However, current quantum computers must dedicate so much computational power to error correction that, in net terms, they are not faster than classical computers.
