Which of the following is the basic unit of information in quantum computing?

Correct option is D

A QUBIT (Quantum Bit) is the smallest unit of quantum information. Unlike classical bits, which can represent either 0 or 1, qubits leverage quantum superposition, allowing them to exist in a combination of both states simultaneously. This property significantly increases the computational power of quantum computers.
Important Key Points:
1. Superposition: Qubits can process multiple combinations of 0 and 1 at the same time, exponentially increasing computational possibilities.
2. Entanglement: Qubits can be linked such that the state of one directly influences the state of another, even at a distance.
3. Quantum Gates: Qubits are manipulated using quantum gates, which are similar to logic gates in classical computing.
4. Applications: Qubits enable advanced applications in cryptography, drug discovery, optimization problems, and AI development.
5. Challenges: Qubits are prone to decoherence, where quantum states are lost due to environmental interference.
Knowledge Booster:
· Physical Representation of Qubits: Qubits are implemented using particles like photons, electrons, or superconducting circuits.
· Quantum Supremacy: Achieved when a quantum computer solves a problem that is infeasible for classical computers.
· Global Players: Companies like Google, IBM, and Microsoft are leading quantum computing research.
· Current Quantum Computers: Still in the experimental stage, with limited qubits but rapid advancements being made.
