Quantum Computing Basics
Understanding the fundamental principles of quantum computing is essential for grasping the complexities of Quantum Federated Learning (QFL) and its applications in collaborative model training. Quantum computing operates based on the principles of quantum mechanics, offering distinct advantages over classical computing.
In classical computing, information is stored in bits that are either 0s or 1s, allowing for linear processing of data. On the other hand, quantum computing utilizes quantum bits or qubits, which can exist in multiple states simultaneously due to superposition, exponentially increasing computational power.
One of the key differences between quantum and classical computing is the concept of entanglement, where qubits can be correlated regardless of the distance between them. This property enables quantum computers to process vast amounts of data in parallel, leading to a significant speedup in certain calculations compared to classical computers.
Additionally, quantum computing benefits from quantum tunneling and interference phenomena, allowing for the solution of complex problems that are infeasible for classical computers within a reasonable timeframe.
How QFL Works
