    Study Notes

    Classical vs Quantum Computers

    • Classical computers use bits to store and process information, whereas quantum computers use qubits (quantum bits).
    • Qubits can exist in multiple states simultaneously, allowing for parallel processing and exponential scaling.

    Quantum Mechanical Phenomenon

    • Quantum particles can exist at multiple locations at the same time due to the phenomenon of superposition.
    • Superposition enables qubits to process multiple possibilities simultaneously, making quantum computers more efficient.

    Qubits vs Classical Bits

    • Qubits can exist in multiple states (0, 1, and both 0 and 1 simultaneously) due to superposition, whereas classical bits can only be in one of two states (0 or 1).
    • Qubits are highly sensitive to their environment and require careful control to maintain their state.

    Significance of Quantum Computers

    • Tapping into the quantum mechanical phenomenon allows quantum computers to solve certain problems much faster than classical computers.
    • Quantum computers have the potential to solve complex problems that are currently unsolvable or require an impractical amount of time to solve.

    Entanglement

    • Entanglement is a phenomenon where two or more particles become connected, allowing their properties to be correlated regardless of distance.
    • Entanglement enables qubits to be connected and processed simultaneously, further increasing the power of quantum computers.
