Quantum computing applies the properties of quantum physics to process information. Operating with nanoscale components at temperatures colder than intergalactic space, quantum computing has the potential to solve some of the world’s toughest challenges. Taking only days or hours to solve problems that would take billions of years using today’s computers, quantum computers will enable new discoveries in the areas of healthcare, energy, environmental systems, smart materials, and beyond.
In quantum computing, a qubit (short for quantum bit) is a unit of quantum information—similar to a classical bit. Where classical bits hold a single binary value such as a 0 or 1, a qubit can hold both values at the same time in what's known as a superposition state. When multiple qubits act coherently, they can process multiple options simultaneously. This allows them to process information in a fraction of the time it would take even the fastest non quantum systems.
Where current computers would require tens of billions of years to solve some of the world’s most challenging problems, a quantum computer would be able to find a solution in only minutes, hours, or days. Quantum computing will enable researchers to simulate and develop new catalysts and materials, improve medicines, accelerate advances in artificial intelligence, and even answer fundamental questions about the origins of our universe.
