Quantum Computing Fundamentals
This section covers the basic building blocks of quantum computing, including qubits, quantum gates, superposition, and entanglement. It lays the groundwork for understanding how quantum systems process information.
- Qubits can exist in superposition, representing 0 and 1 simultaneously.
- Quantum gates are unitary operators that transform qubit states reversibly.
- Entanglement allows qubits to be linked, where the state of one instantly influences the other.
- The gate-based model is the most common framework for quantum computation.
Quantum Algorithms
This part details foundational quantum algorithms that demonstrate significant speedups over classical counterparts, such as Shor's for factoring, Grover's for search, and HHL for linear systems.
- Shor's algorithm offers exponential speedup for integer factorization.
- Grover's algorithm provides a quadratic speedup for unstructured database search.
- The HHL algorithm can exponentially speed up solving linear systems under certain conditions.
- Quantum Phase Estimation (QPE) is a critical subroutine for many advanced algorithms like Shor's.
Quantum Machine Learning (QML) & QDL
This section explores the integration of quantum computing with machine learning, covering data encoding techniques and specific QML algorithms like SVM, k-means, and PCA, as well as Quantum Deep Learning (QDL).
- Data encoding (basis, amplitude) is crucial for converting classical data into quantum states.
- Quantum SVM and k-means can achieve significant speedups for classification and clustering.
- Quantum PCA offers exponential speedup for dimensionality reduction.
- QDL aims to enhance neural networks with quantum principles for improved performance and memory.
