Frequently asked questions

How is a qubit different from a standard computer bit?

A standard bit holds either a zero or a one, while a qubit can exist in a superposition of both states simultaneously. This allows quantum processors to explore many possible solutions at once. Classical bits are stable, but qubits are fragile and require extreme cooling to maintain their state.

When will quantum computers become commercially available for general use?

General-purpose, fault-tolerant quantum computers are not expected to be commercially available until the 2030s or 2040s. Current devices are noisy intermediate-scale quantum machines, useful for specific research tasks. Major companies like IBM and Google are actively working to solve error correction challenges to achieve this milestone.

Will quantum computers break current internet encryption methods?

Yes, large-scale quantum computers could break widely used encryption standards like RSA and ECC. This threat has led to the development of post-quantum cryptography, which uses mathematical problems resistant to quantum attacks. The National Institute of Standards and Technology has already standardised several new algorithms to prepare for this transition.

What temperature is required to operate a superconducting quantum computer?

Superconducting qubits must operate at temperatures near absolute zero, typically around 15 millikelvin. This is colder than outer space. Dilution refrigerators achieve this temperature to prevent thermal noise from destroying the delicate quantum states, ensuring the hardware functions correctly during complex calculations.

How many qubits are needed to solve complex chemistry problems?

Simulating a single medium-sized molecule, such as a drug candidate, may require thousands of logical qubits. Current hardware has fewer than a thousand physical qubits, which are error-prone. Researchers estimate that millions of physical qubits are needed to create the logical qubits required for practical, error-free chemical simulations.
