Question 1

What's the difference between Quantum Computing and classical computing?

Accepted Answer

Classical computers use bits (0 or 1). Quantum computers use qubits, which can represent combinations of 0 and 1 (superposition) and can be linked (entanglement). This can make some types of problems—like certain simulations, optimization, and cryptography-related math—potentially much faster, but most everyday workloads still run best on classical computers.

Question 2

When should I use Quantum Computing?

Accepted Answer

Use quantum computing when you have a research or innovation need and a problem that maps well to known quantum approaches—such as molecular simulation, certain optimization problems, or exploring post-quantum cryptography impacts. In practice, most teams start with a hybrid approach: run the main application on classical cloud infrastructure and call quantum hardware only for specific subproblems, while validating results against classical baselines.

Question 3

How much does Quantum Computing cost?

Accepted Answer

Costs depend on (1) the provider and device type (gate-based vs annealing), (2) how many runs/shots you execute, (3) queue time and reserved capacity options, and (4) simulator usage and classical compute used for pre/post-processing. Many platforms charge per task/job plus per-shot or per-usage unit, and simulators are typically billed like standard cloud compute. Because experiments often require many iterations, budgeting should include repeated runs, error-mitigation overhead, and classical optimization loops.
