TL;DR: Key points with love ❤️Toronto startup Xanadu Quantum Technologies Inc. has achieved a worldwide first by creating a single light-based quantum chip that embodies a powerful type of error-detection code (Gottesman-Kitaev-Preskill or GKP codes). This breakthrough is a significant step towards developing scalable, reliable quantum computers for commercial use, addressing the challenge of quantum systems being error-prone.
Trending- 1 2001: Gottesman-Kitaver-Preskill (GKP) codes first proposed.
- 2 Earlier this year: Xanadu published a result showing how its quantum computing could be easily modularized.
- 3 Last week: Nord Quantique demonstrated successful encoding of microwave photons with a GKP code.
- 4 Wednesday (current article): Xanadu's technical description of the new chip was published in the journal Nature.
- Significant step towards scalable and reliable quantum computing
- Potential for quantum computers to operate at data center scale
- Continued race in quantum computing development
What: Toronto startup Xanadu Quantum Technologies Inc. has created the first single light-based quantum chip with a powerful error-detection code (GKP code).
When: Wednesday (technical description published); Earlier this year (Xanadu published modularization result); Last week (Nord Quantique demonstrated GKP code)
Where: Toronto, Canada (Xanadu's location); University of Arizona in Tucson, Arizona, USA (Dr. Soh's location); Sherbrooke, Quebec, Canada (Nord Quantique's location); Palo Alto, California, USA (PsiQuantum's location).
Why: To overcome the inherent error-proneness of quantum systems and enable the development of scalable, reliable quantum computers for commercial applications.
How: Xanadu researchers created a chip that corrals photons into a quantum state to form a GKP qubit, with four outputs for error detection.
