Week End Reading from TechAptitude!

Great strides are being made in the effort to take Quantum Networks out of the lab and into the real world.

Quantum networks hold the potential to enable fundamentally new capabilities, including ultra-secure communication with unbreakable encryption, distributed quantum computing, and hold out the promise of creating a “Quantum Internet”.

It's not in the least bit ironic that #QuantumMechanics yields averaging functions ( yes _ it's not just one, you twitfarks) that make determination of an at least *conditionally objective* (and stable) observable reality, a thing. When high strangeness intrudes ( in the presence of say #NHI, for instance) it's because they bring their local bubble with them. That should not be surprising, in the arena of advanced intelligence. You just drew your hand on the cave wall again, didn't you ?

Quantum mechanics breaks every intuition you have about reality — and yet it's the most precisely tested theory in the history of science.
Particles in multiple states. Probability over certainty. A universe nothing like what we see.

One-way quantum synchronization could make quantum computers more reliable

Scientists at RIKEN have proposed a new way to make quantum systems synchronize in only one direction—like a one-way street for sound particles known as phonons. The breakthrough combines two quantum effects to create a form of one-way quantum synchronization that remains surprisingly stable even when exposed to manufacturing flaws and environmental noise, two major obstacles that have long hindered real-world quantum technologies.

Poetry: Representations

Finally, a revelation! I was asking myself: Why do I often find ancient, terse, illustration-free textbooks easier to follow than their modern, friendly, playful, illustrated, multi-media-enhanced counterparts? Case in point (and I know that not everybody will agree): Paul Dirac's legendary Principles of Quantum Mechanics or the definitive course on theoretical physics, the volumes by Landau and Lifshitz. In modern lectures and articles such resources may be announced as "valuable but not […]
