Part 9/11:
Each of these approaches faces significant engineering challenges, especially around the issues of decoherence (the loss of quantum information due to interaction with the environment) and scalability (the practical ability to increase qubit numbers while maintaining entangled states). Strategies for overcoming these hurdles include quantum error correction to create fault-tolerant systems and sophisticated shielding methods to protect quantum states from environmental noise.
Future Applications
While the complete realization of quantum computers capable of solving practical problems is still in the future, their potential applications are diverse and far-reaching. Fields such as:
