Quantum Computing Quiz

Why do advanced quantum computers need to be kept near absolute zero?

• To reduce the size of the computer

• To prevent overheating of the system

• To ensure the computer operates faster

• To make use of quantum phenomena and avoid calculation errors

What is a unique feature of a qubit compared to a classical bit?

• It can only represent a zero

• It can represent both one and zero simultaneously

• It can only represent a one

• It cannot represent any value

What is decoherence in the context of quantum computing?

• The method of increasing qubit speed

• The technique of isolating qubits from each other

• The interaction of qubits with the environment causing loss of information

• The process of cooling qubits

What is one approach to managing the heat generated by quantum computers?

• Using traditional cooling fans

• Developing qubits that can operate at warmer temperatures

• Increasing the size of the computer

• Reducing the number of qubits

What advantage do silicon-based qubits have over superconductor-based qubits?

• They are cheaper to produce

• They can operate at much higher temperatures

• They require no cooling at all

• They are faster in processing data
