2. Unlike classical bits, quantum bits or qubits can exist in multiple states simultaneously.

3. Superposition allows quantum computers to process vast amounts of information in parallel.

Superposition in quantum computing allows qubits (quantum bits) to exist in multiple states simultaneously. Unlike classical bits, which can only be in one of two states (0 or 1) at a time, qubits can be in a superposition of both states simultaneously. This property enables quantum computers to perform computations on all possible inputs at the same time, exponentially increasing their processing power for certain types of problems. By exploiting superposition, quantum algorithms can explore many potential solutions simultaneously, leading to faster problem-solving in areas such as optimization, cryptography, and quantum simulation.

4. Entanglement is a phenomenon where qubits become correlated and the state of one qubit can affect another, regardless of distance.

Entanglement is a unique quantum mechanical phenomenon where two or more qubits become correlated with each other in such a way that the state of one qubit instantaneously affects the state of another, no matter the distance between them. This correlation persists even if the entangled qubits are separated by vast distances, violating classical notions of locality and suggesting a deeper interconnectedness at the quantum level.

When qubits are entangled, the quantum state describing their combined system cannot be decomposed into individual states for each qubit; instead, the system must be described as a whole. This means that measuring the state of one entangled qubit instantly determines the state of the other(s), even if they are light-years apart. This instantaneous correlation is what Einstein famously referred to as "spooky action at a distance."

Entanglement is crucial for quantum computing because it allows quantum algorithms to operate on a massively parallel scale. By entangling qubits, computations can be performed collectively across all entangled states simultaneously, vastly increasing the computational power and efficiency of quantum computers for certain tasks such as quantum teleportation, cryptography (quantum key distribution), and more.

In summary, entanglement is a profound quantum phenomenon where the states of qubits become interconnected in such a way that changes in one qubit are instantly reflected in others, regardless of their physical separation. This property underpins many of the potential advantages of quantum computing over classical computing.
