Serious Quantum Excitement With Entanglement Transfer!

Posted by Scott Holstad on September 3, 2019

Okay, my quantum (and other physicist/scientist/researcher/etc.) friends and colleagues. I’m sure some of you know this and may already have read the paper, but if not, get ready! We all know that while people are working hard in/on quantum computers, there’s still a world of difference between that and a quantum Internet. Entanglement. Quantum information can’t be copied and transmitted over a traditional network. Quantum particles require a different interface, allegedly. However, Austrian researchers led by Ben Lanyon have successfully completed a documented unreal experiment: They were essentially able to transmit quantum entanglement 50 km over basic fiber!

The paper discussing this experiment was published August 27, 2019 and you can find it at “Light-matter entanglement over 50 km of optical fibre.”

 

Caveat: For those less familiar with quantum research, the paper might appear to be fairly technical, but not overly so for many, I believe. Graduate level and above quantum physics. Don’t get mad at me if I turn out to be wrong. Quantum’s not for everyone…

Important! Quantum Computing

Posted by Scott Holstad on December 9, 2018

This is a brief post about a very important subject. Unfortunately, a lot of people don’t really know just how important it is, let alone know anything about it at all.

Listen please! This is a very important & urgent topic. I strongly support US government-funded research in quantum science & quantum computing. And perhaps most importantly, encryption capable of reliably standing up to the power of those using such computers against others, etc. Quantum computing is technically here. And it’s unreal! Current encryption standards are about to become obsolete & useless to those who possess this technology. As this article states, “Quantum computers pose a significant risk to encrypted devices & communications. Due to many current encryption methods being based on a complex series of math equations, encryption becomes more vulnerable to quantum computers which can process up to 100 million times faster than a traditional computer. As such, even quantum computer prototypes have the ability to invalidate many forms of cybersecurity.” And while the technology is already here, & as it’s likely to be broadly available in the next 5-10 years, the truly worrisome thing is that most experts feel that sufficient security technology to protect against such systems is 20 years away. By then, it won’t even matter anymore. Please educate yourselves on this crucial topic & support serious research. It’s truly critical.
