Quantum is all the rage, but sorting real science from pop science isn’t easy. A century ago, physicists realized subatomic particles don't follow classical rules—electrons exist in superpositions of probability until observed, and entangled photons collapse instantly across vast distances. From Einstein’s doubts to atomic clocks and modern quantum communications, we explore the weird realities, unsolved mysteries, and transformative technology shaping our quantum future.

Happy New Year! 2025 was a dynamic year for the high-tech sector, including AI, space, quantum, and PNT, the areas where Xairos play. Here's our perspective:

The foundational need to know our location and time is at the heart of position, navigation, and timing (PNT) infrastructure. For the last half century, PNT and GPS (the US Global Positioning System) have been interchangeable; there are 8 billion GPS receivers in the world – one for every person on Earth - and GPS pervades all aspects of our lives: our location on digital maps and ridesharing apps, commercial and airline navigation, the timestamp on ATM, credit card and stock

Our relationship to time has always advanced in lockstep with technology. Our ancestors cared about seasons, so created calendars tied to...
