We interact with bits and bytes everyday — whether that’s through sending a text message or receiving an email. There’s also quantum bits, or qubits, that have critical differences from common bits and bytes. These photons — particles of light — can carry quantum information and offer exceptional capabilities that can’t be achieved any other way. Unlike binary computing, where bits can only represent a 0 or 1, qubit behavior exists in the realm of quantum mechanics. Through “superpositioning,” a qubit can represent a 0, a 1, or any proportion between. This vastly increases a quantum computer’s processing speed compared to today’s computers. Experts are now investigating the inside of a quantum-dot-based light emitter.
