Cryptography with Quantum Computing

What is the square root of -1? This is the first tool to understanding quantum computing. That is, your imagination! Quantum computing harnesses the bizarre principles of quantum mechanics—superposition and entanglement—to perform calculations. Unlike classical bits that are either 0 or 1, quantum bits (qubits) can be both simultaneously (superposition). Entanglement links qubits, so they share the same fate regardless of distance. This allows quantum computers to process vast amounts of information in parallel, potentially solving problems intractable for even the most powerful supercomputers, like drug discovery or complex optimization. Additionally, it allows for diverse cryptological methods of encryption. For example, a quantum wallet could be intrinsically linked to only one individual that could, from anywhere in the world, access the quantum money in it. Because of entanglement, there would be no way to steal quantum money. It would immediately become fundamentally altered, disappearing from the economic world, devoid of value, much like a coupon, if the potential thief was to possess it.
