PsiQuantum aims to build a pioneering quantum computer using photons, while Norway works on the world’s longest and deepest subsea road tunnel beneath the North Sea.
- PsiQuantum targets a functional quantum computer leveraging photons.
- Norway builds the deepest subsea road tunnel at 1,280 feet below sea.
- Engineering advances persist amid complex technical and environmental challenges.
What happened
PsiQuantum, a quantum computing startup founded in 2016 by four UK physicists, is developing a quantum machine that uses photons traveling through optical switches to perform computations potentially unsolvable by classical computers. The design will encompass hundreds of chips in stainless steel cabinets housed in a data center-like room, although the machine itself has yet to be realized.
Meanwhile, in Norway, construction is underway for a subsea highway tunnel stretching 16.6 miles beneath the North Sea fjords. This tunnel will reach depths of 1,280 feet below sea level, making it the longest and deepest of its kind. The endeavor demonstrates significant engineering capabilities under harsh environmental conditions.
Why it matters
PsiQuantum’s approach to quantum computing could eventually deliver transformative capabilities in fields that require massive computational power, such as cryptography, material science, and complex simulations. Achieving a functional quantum computer would mark a major milestone in technology and herald new possibilities for problem-solving.
The Norwegian subsea tunnel project highlights the continuing ambition in infrastructure development despite logistical and environmental challenges. Such infrastructure is critical for improving transportation and connectivity in regions with complex geography, and underscores human capacity for large-scale engineering projects.
What to watch next
Key developments to monitor include PsiQuantum’s progress toward building and validating their photon-based quantum computer architecture. Success will depend on scaling their technology and reliably detecting photon states to perform precise computations, which remains an intricate technical challenge.
For the subsea tunnel, attention will focus on the timeline for completion and the innovative construction techniques used to manage immense underwater pressure and ensure safety. The project’s outcomes may influence future infrastructure endeavors even beyond Norway.
