It’s All About Time: Satellite Based Quantum Time Synchronization
It is well understood that all modern networks and electronics rely on a timing signal from GPS that is not nearly secure or accurate enough for the job.
How do you solve this problem? With entangled photons!
Our Product and Strategy Lead, Tanya Ramond, describes the path to a new space-based timing architecture using quantum technology in a recent TTI/Vanguard presentation that you can check out here.
The quantum links form the core of a secure and accurate time distribution between satellites and ground nodes. The last mile timing distribution can utilize traditional methods, but will benefit from the recent Facebook Time Appliance which was released as an open source design.
The timing accuracy improvement yields huge benefits for distributed databases: “making the timekeeping 80x more precise (making any time discrepancies 80x smaller) made a distributed database run 3x faster – an incredible performance boost on the same server hardware, just from keeping more accurate and more reliable time.”
But the long term goal is an accurate and secure timing system that is completely independent of GPS, providing benefits for all telecommunications, networks, industrial robotics, IOT devices, autonomous vehicles, and position devices.

The More You Know…

In presentations, we like to highlight the events of January 26, 2016, when communication networks around the world started to fail due to a 13 millisecond error in GPS clocks.
But in reality GPS failures occur all the time and this error is only one of dozens of major disruptions.
This has spurred governments and private industry to develop PNT solutions that augment GPS that are mostly focused on delivering position information over RF signal.
Our solution is focused on timing, addressing the majority of the $1.4T in economic benefit delivered by GPS.
At its core is our quantum optical technology that is orders of magnitude more accurate and secure than GPS and other RF-derived time transfer solutions, as described in our recent presentation.
And, despite the connotation of quantum hardware being difficult, this system architecture is actually much simpler: we only need one satellite for time distribution instead of many satellites to derive position; don’t need RF spectrum; can address enterprise customers with fixed sites as well as terrestrial networks; and leverages off-the-shelf hardware and quantum funding.
