Quantum computing has been a futuristic technology for many years. While the theory behind quantum physics and quantum computing has been around for decades, Implementations have lagged behind. For several years, quantum computing has been“just around the corner” but has never arrived. In the last few years, this has changed, and the development of quantum computing has accelerated rapidly. Today, IBM has a 127-qubit quantum computer and plans to reach over 4,158 qubits by 2025. The emergence of quantum computing has significant implications for technology. Quantum computers work very differently from the classical ones today, making previously infeasible computations possible. While this has its benefits, it also has its downsides, especially in the areas of cryptography and cybersecurity.
