What is the primary difference between classical and quantum computing?

• Quantum computing is slower than classical computing.

• Classical computing is based on quantum mechanics.

• Quantum computing can solve problems faster and handle more variables than classical computing.

• Classical computing uses qubits, while quantum computing uses bits.

What is a qubit?

• A classical computing bit that can be either 0 or 1.

• A type of quantum algorithm.

• A unit of classical computing power.

• A quantum bit that can hold values of 0, 1, or both simultaneously.

Why are qubits considered unstable?

• They can hold only one value at a time.

• They require high temperatures to function.

• They are easily influenced by external factors and have a short shelf life.

• They are made of unstable materials.

What is the role of startups in the quantum computing market?
