    Study Notes

    Quantum Computing

    • Quantum computing is a new approach to computing, leveraging quantum mechanics to solve problems classical computers struggle with.
    • Unlike classical computers using bits (0 or 1), quantum computers use qubits, which can exist in multiple states (0 and 1 simultaneously) due to superposition.
    • Entanglement allows qubits to be correlated, meaning measuring one qubit instantaneously affects the others, no matter the distance.
    • Quantum mechanics introduces wave-particle duality and quantization, unlike classical physics' continuous properties.

    What Comes After Supercomputers?

    • The COVID-19 pandemic highlighted issues classical computers face with vast amounts of complex data.
    • Scientists need to analyze vast amounts of data, understand how viruses spread, and test potential treatments quickly.

    Bits and Information Processing Paths

    • Classical computers use bits (0 or 1) to process data, executing processes sequentially.
    • Finding solutions involves calculating every possible option and selecting the best one.
    • The calculation time grows exponentially as the number of variables increases.

    Schrödinger's Cat

    • Schrödinger's cat thought experiment illustrates superposition, where the cat can exist in both alive and dead states simultaneously until observed.
    • Observation forces the system into one outcome (superposition collapses), impacting quantum computing's measurement problem.
    • The process of superposition and measurement helps understanding quantum mechanics better.

    Quantum Information Science Kit (Qiskit)

    • Qiskit is an open-source framework for quantum computing, enabling the design, execution, and analysis of quantum circuits using classical computers.
    • Qiskit Terra: This is the fundamental foundation within Qiskit to form quantum circuits and implement quantum gates.
    • Qiskit Aer: Provides high performance simulators for quantum experiments to ensure they run reliably with no need for actual quantum computers.

    Key Concepts in Quantum Mechanics

    • Wave-Particle Duality: Particles like electrons or photons have wave and particle qualities simultaneously.
    • Quantization: Energy and momentum only exist at specific discrete values ("quanta"), unlike classical physics with continual changes.
    • Uncertainty Principle: Uncertainty exists in determining certain pairs of properties like position and momentum in quantum particles.
    • Superposition: Particles exist in multiple states or positions simultaneously until measured.
    • Entanglement: Particles become linked, and measuring one immediately affects the others, irrespective of distance.

    Quantum Algorithms and Their Applications

    • Quantum algorithms leverage quantum mechanics to perform calculations and solve problems more efficiently than classical approaches.
      • Shor's Algorithm: Factors large integers, impacting cryptography.
      • Grover's Algorithm: Searches unstructured databases or large datasets.
      • Quantum Fourier Transform (QFT): A quantum version of the classical Fourier transform, crucial in various quantum algorithms like Shor's algorithm.
      • Quantum Phase Estimation: Used to determine eigenvalues (properties) of quantum systems.
      • Quantum Approximate Optimization Algorithm (QAOA): Calculates approximate optimal solutions for combinatorial optimisation problems.
      • Variational Quantum Eigensolver (VQE): Provides a method to estimate ground state energies of molecules or systems.
      • Quantum Annealing (D-Wave): Provides a solution to solve optimization issues by changing the quantum system's energy state.
      • HHL Algorithm (Harrow-Hassidim-Lloyd): Solves systems of linear equations faster than conventional solutions.

    Quantum Applications

    • Quantum algorithms impact diverse fields like cryptography, optimisation (supply chain logistics, and finance), chemistry (drug discovery, and materials science), machine learning, artificial intelligence, and physics simulation.
