For instance, factorizing large numbers, simulating quantum systems, and optimizing complex problems are areas where quantum algorithms show great promise. These capabilities could have transformative applications in cryptography, drug discovery, material science, optimization, and more.

Quantum computers also benefit from another property called entanglement. Entanglement enables the correlation of qubits, even when physically separated. Manipulating one entangled qubit affects its correlated partner instantaneously, regardless of the distance between them. This property opens up possibilities for secure communication and more efficient data processing.

However, it's important to note that quantum computing is still in its early stages of development. Challenges like decoherence, which refers to the fragility of qubits and their susceptibility to external disturbances, pose significant hurdles. Researchers are actively working on error correction techniques and improving qubit stability to make quantum computers more reliable.

In summary, quantum computing harnesses the principles of quantum mechanics to perform advanced computations. Its potential applications span various fields, and it offers advantages such as exponential speedup and the ability to solve complex problems that are currently infeasible for classical computers. While there are challenges to overcome, the progress made in quantum computing holds promise for groundbreaking advancements in multiple domains.
