Quantum Mechanics

Britain has scored a world-first with a series of test flights to demonstrate the core technologies of a future quantum navigation system that's designed to foil one of the most potentially dangerous, yet not very widely publicized, threats that transportation faces: GPS jamming and spoofing.

Causality is key to our experience of reality: dropping a glass, for example, causes it to smash, so it can’t smash before it’s dropped. But scientists have now demonstrated how that understanding of time can be violated to charge a quantum battery.

Using very small atoms to guide very large submarines, Q-CTRL has been awarded a contract by the Australian Department of Defence to develop quantum mechanics systems for the AUKUS treaty partners to navigate subs on long underwater missions.

It may seem like electronics will always get faster, but at some point the laws of physics intervene. Scientists have now calculated the absolute speed limit – the point at which quantum mechanics prevents microchips from getting any faster.

Sandia National Laboratories is developing an avocado-sized vacuum chamber made out of titanium and sapphire that could one day use quantum mechanical sensors to provide GPS-grade navigation without the need for satellites.

​​Researchers have come up with a way to generate truly random numbers using quantum mechanics. The method uses photons to generate a string of random ones and zeros, and leans on the laws of physics to prove that these strings are truly random, rather than merely posing as random.

Scientists at the Kavli Institute of Nanoscience at the Delft University of Technology (TUDelft) have developed a memory technology that achieves the ultimate physical limit by using individual atoms to represent a single bit of data.

Researchers have found a way to speed up the rate at which data can be securely transmitted using quantum cryptography. It's a development that could pave the way to faster, ultra-secure communications that are impossible to spy on.

A new device is set to make unbreakable, quantum-based cryptographic security available for everyone for the very first time. To do this, the device incorporates the quantum mechanics of random photon polarization to generate random numbers and create cryptographic keys.

Minecraft players can now be slightly closer to parsing the perplexities of quantum theory, thanks to qCraft. Now Minecraft can have more quantum teleportation, observer dependencies, and Schrödinger’s Cat.
