Xanadu Borealis Achieves Quantum Advantage With Public-Facing Photonic Quantum Computer

Xanadu has achieved a landmark in quantum computing with the deployment of Borealis, the first publicly accessible, programmable photonic quantum computer to demonstrate quantum computational advantage. The machine synthesizes 216 squeezed-state qubits, entangled in three dimensions, and outperforms the world’s fastest supercomputers at a specific task by a factor of over 50 million; a calculation that would take a classical supercomputer approximately 9,000 years, Borealis completes in 36 microseconds. This achievement, published in Nature, marks the first time a startup company has reached this milestone and the first instance of quantum computational advantage realized in Canada. Christian Weedbrook, founder and CEO of Xanadu, said this demonstrates the talent at Xanadu and the scalability of photonic quantum computers.

Borealis Demonstrates Quantum Computational Advantage with 216 Qubits

Borealis, a 216-qubit photonic quantum computer developed by Xanadu, has achieved a feat previously confined to theoretical demonstrations; it now demonstrably outperforms the world’s most powerful supercomputers at a specific computational task. The machine synthesizes quantum states using squeezed-state qubits, entangled across three dimensions, and delivers results at a speed unattainable by classical systems, marking the first publicly available quantum computer to reach this milestone. Previous demonstrations of quantum advantage existed, but Borealis distinguishes itself as the first programmable photonic quantum computer to achieve this, granting users complete control over its quantum gates, a critical step toward practical applications. The speed differential is striking; generating a single sample that requires approximately 9,000 years for the fastest supercomputer takes Borealis just 36 microseconds, representing a runtime advantage exceeding 50 million times that of prior photonic experiments.

This computational leap is not merely academic, but a validation of Xanadu’s approach to quantum computing and a step toward solving currently intractable problems in fields ranging from materials science to financial modeling. Accessibility is central to Xanadu’s strategy; Borealis is available through Xanadu Cloud and Amazon Braket, allowing researchers and developers worldwide to test and validate quantum advantage claims firsthand. Richard Moulds, General Manager of Amazon Braket at AWS, noted that this access allows, for the first time, any researcher or developer to validate a claim of quantum advantage and evaluate how photonic quantum computing may eventually expand their choice of compute technologies, enabling them to innovate more quickly. This deployment in Canada also represents a first for the nation and for a startup company in the quantum computing space, signaling a broadening of innovation beyond established research institutions.

Photonic Quantum Computing Accessible via Xanadu Cloud & Amazon Braket

The field of quantum computing is rapidly shifting from theoretical possibility to demonstrable, albeit limited, computational power. Several companies are now offering access to early-stage quantum processors via cloud platforms, but a recent development from Xanadu significantly alters the playing field by achieving and publicly deploying quantum computational advantage with its Borealis machine. This level of control distinguishes Borealis from earlier systems with restricted functionality, opening the door to broader exploration and algorithm development. This leap in performance isn’t merely academic; it signals a tangible progression in photonic quantum computing’s ability to tackle problems intractable for conventional machines. Accessibility is further broadened through integration with Amazon Braket, AWS’s fully managed quantum computing service, allowing researchers and developers to validate claims of quantum advantage and explore the potential of photonic quantum computing as a viable technology.
