Which one of the following is the context in which the term “qubit” is mentioned?
- Cloud Services
- Quantum Computing
- Visible Light Communication Technologies
- Wireless Communication Technologies
Explanation
Option (b) is correct
- Quantum computers use qubits (quantum bits) as the basic unit of information. Binary bits can represent either 0 or 1, but qubits can exist in a superposition of states, meaning they can represent both 0 and 1 simultaneously. This allows qubits to carry more information. This property also allows quantum computers to perform multiple calculations parallelly.
Option (a) is incorrect
- Cloud Services refer to the delivery of computing services such as servers, storage, databases, networking, software, and more over the cloud (internet).
Option (c) is incorrect
- Visible Light Communication (VLC) refers to the use of visible light for communication purposes, such as Li-Fi (Light Fidelity). VLC uses light in the visible spectrum to transmit data wirelessly.
Option (d) is incorrect
- Wireless Communication Technologies involve the transmission of data over electromagnetic waves without physical connections. This includes technologies like Wi-Fi, Bluetooth, and cellular networks.
