QUANTUM COMPUTING(PART-1)

 Introduction:

Quantum computing is a type of computing that takes advantage of the principles of quantum mechanics to perform calculations. It differs fundamentally from classical computing, which relies on bits to encode information as either 0s or 1s. In contrast, quantum computing uses quantum bits or qubits, which can represent and store information as 0s, 1s, or both simultaneously (a quantum superposition of states).

Let's delve deeper into the key concepts and principles that underpin quantum computing:

Quantum Bits (Qubits): 

• Basic Unit: In classical computing, the basic unit of information is the bit, which can represent a state of either 0 or 1.
• Quantum Superposition: Qubits, on the other hand, can exist in a superposition of states, meaning they can represent both 0 and 1 simultaneously until measured.
• Measurement: When a qubit is measured, it collapses to a classical state (either 0 or 1).

Quantum Entanglement:

•    Correlation: Qubits can become entangled, where the state of one qubit is directly related to the state of another, even if they are separated by large distances.

•    Instantaneous Effect: Changes to one entangled qubit can instantly affect the state of the other, a phenomenon Einstein famously referred to as "spooky action at a distance."
