### What is quantum computing? ### What is quantum computing?
Nature -- including molecules like caffeine -- follows the laws of quantum mechanics, a branch of physics that explores how the physical world works at the most fundamental levels. At this level, particles behave in strange ways, taking on more than one state at the same time, and interacting with other particles that are very far away. Quantum computing harnesses these quantum phenomena to process information in a novel and promising way.

Quantum Computing is the study of quantum computation systems that make use of quantum mechanical phenomena, such as entanglement and superposition. Classical binary digit electronic computers (like your own PC!) are based on transistors, which stores data in binary digits (bits), each of which can be in one of two states (0 or 1). Quantum computers on the other hand store data into quantum bits, which can be in superpositions of states.

Classical binary digit electronic computers (like your own PC!) are based on transistors, which stores data in binary digits (bits), each of which can be in one of two states (0 or 1). Quantum computers on the other hand store data into quantum bits (Qubits), which can be in so-called 'superpositions' (that of being simultaneously in all possible positions).
Because a quantum computer is able to take advantage of these quantum mechanical properties, it is theorized that large scale quantum computers will be able to solve certain problems far quicker than a classical computer.

Classical computers encode information in bits. Each bit can take the value of 1 or 0. These 1s and 0s act as on/off switches that ultimately drive computer functions. Quantum computers, on the other hand, are based on qubits, which operate according to two key principles of quantum physics: superposition and entanglement. Superposition means that each qubit can represent both a 1 and a 0 at the same time. Entanglement means that qubits in a superposition can be correlated with each other; that is, the state of one (whether it is a 1 or a 0) can depend on the state of another. Using these two principles, qubits can act as more sophisticated switches, enabling quantum computers to function in ways that allow them to solve difficult problems that are intractable using today’s computers.
