     Potential Risks

     1. Cryptographic Vulnerability:
        • Quantum computers could break widely used cryptographic schemes like RSA and ECC, leading to potential breaches in data security. The need for quantum-resistant cryptography is urgent.
     2. High Cost and Accessibility:
        • The development and maintenance of quantum computers are extremely expensive. Access to quantum computing resources may be limited to a few large organizations and governments, potentially exacerbating technological inequality.
     3. Technical Challenges:
        • Quantum computing faces significant technical hurdles, including error rates, decoherence, and qubit stability. These challenges must be overcome before practical and reliable quantum computers can be developed.
     4. Ethical and Security Concerns:
        • The power of quantum computing could be misused for malicious purposes, such as breaking encryption to access sensitive information or developing advanced weaponry. Ethical guidelines and regulations will be necessary to mitigate these risks.
     5. Job Displacement:
        • As with any disruptive technology, quantum computing may lead to job displacement in certain sectors. Professionals in fields reliant on classical computing may need to reskill to stay relevant.
