Quantum Pigeonhole Effect | Quantum Computing Weekly #9

This is a syndicated version of my weekly e-mail round-up of news about Quantum Computing. Visit the homepage to subscribe to updates and check out previous issues.

🎉Happy new year and welcome to the first issue of 2019!

These next two weeks will be a bit on the light side as I’m ramping up work with my company for the new year as well as finally going on my honeymoon — that said, I will still do my best to deliver my favorite quantum computing news and tidbits!

Looking for a particular area of quantum computing you’d like to see covered in the next issue? Ping me and let me know!

Tiny Fact of the week

You may have heard of quantum entanglement, but have you heard of its cousin, cosmic correlation connections? Using pre-selection and post-selection, we can get a connection between two particles — in other words, measurements made in different times (like the future) can affect quantum systems in the present. Check this out to learn more about the research and get an introduction to the idea of how 3 pigeons can occupy two pigeonholes without any being shared. If you’d really like to dive deep down into the pigeon hole, then here’s the original paper.

This week I’d like to draw attention to this great video by Microsoft Research about quantum computing for (classical) computer scientists. It dips into real examples, and uses code written in Q# (based on F#) which I personally hadn’t seen before!
