Xanadu Quantum: the Frontier of Practical Quantum Computing

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.

Xanadu Quantum, founded in 2016 and headquartered in Toronto, is a leading developer of photonic quantum computing that went public on the Toronto Stock Exchange in March 2026. Xanadu’s photonic quantum computing technology uses light and photonic circuits to produce and manipulate qubits. The result is a modular, scalable architecture that the company believes can produce fault-resistant quantum computers with millions of qubits.

Xanadu’s latest hardware, Aurora, announced in 2025, is a 12-qubit machine that demonstrates the potential of Xanadu’s approach. As the world’s first scalable, modular, and networkable quantum computer, Aurora is a testament to the future of quantum computing. Paired with Xanadu’s suite of quantum computing software development tools, these products offer a glimpse of a made-in-Canada quantum industry that may revolutionize computing as we know it.
