2. Introduction to Quantum Computing
Quantum Bits (Qubits)
Qubits, the fundamental
units of quantum
information, can exist in
superposition, allowing
them to represent multiple
states simultaneously.
Quantum
Entanglement
Qubits can become
"entangled," where the
state of one qubit is
dependent on the state of
another, enabling
powerful quantum

Quantum Phenomena
Quantum computing
leverages the unique
properties of quantum
mechanics, such as
superposition and
entanglement, to perform
computations in ways that
are not possible with
classical computers.

3. Principles of Quantum Mechanics
1 Superposition
Qubits can exist in a superposition of multiple states, until they are
measured, at which point they collapse into a single state.
2 Entanglement
Qubits can become entangled, where the state of one qubit is dependent on
the state of another, even when they are physically separated.
3 Uncertainty Principle
The more precisely the position of a particle is determined, the less precisely
its momentum can be known, and vice versa.
