Quantum computers have long been promised to reshape the leading edge of computing technology, facilitating machines capable of completing operations unthinkably time-intensive for classical computers. Leading quantum computing companies including Toronto-based Xanadu Quantum are making this promise a reality, building and bringing quantum computing to the commercial mainstream.
As described by quantum mechanics, at very small scales, particles exhibit special behaviours including superposition, entanglement and interference. Quantum computers utilize these behaviours to complete computations in a fundamentally distinct way from classical computers. While bits in classical computers typically store and represent information as either a 1 or a 0, quantum qubits encode a superposition of likely states enabling analysis of many states in parallel.
