Recap of Week 1 and preview of Week 2

In Week 1, we learned why people are Wanting Quantum. Next, we look forward to Being Quantum.
This brings us to the end of Week 1. We hope that you have a feel for why we are so excited about quantum computers, why we are “Wanting Quantum”.

Quantum computers will change the way we solve some important, but difficult, problems: factoring and search/optimization are perhaps the two best known, but quantum chemistry has a strong case for being the first area where significant contributions will actually be made, and there is a great deal of excitement these days around the integration of machine learning and quantum technology.

This week ended with a long Activity on waves, superposition and interference. These concepts are vital to understanding how quantum algorithms work, so if you don’t yet feel fully comfortable with them, plan to refer back to the corresponding Steps as necessary.

Next week we will introduce the basic ideas of qubits (first one, then larger groups), the enigma of quantum entanglement, and how superposition and interference solve problems for us, then connect these abstract notions to the real world by looking at the physical phenomena that will carry quantum data for us.

You might be feeling overwhelmed, excited, or both. Don’t worry, those feelings are natural! Quantum computing involves phenomena and ideas we don’t encounter in daily life, so naturally it results in a bit of a workout for your brain. We’re here to support your learning as best we can. See you in Week 2!


これで第1週は終わりです。 この週を通して、私たちがなぜ量子コンピュータにとても興味を抱いており、なぜ「量子を望んでいる」かを少しだけでも感じていただけていたら幸いです。

量子コンピュータは、一部の重要かつ困難な問題を解決する手法/手段を与えてくれることでしょう。 素因数分解と検索/最適化の2つは最もよく知られていますが、特に量子化学は実際に大きな進歩を生むことが期待されています。また、機械学習への量子技術の応用の可能性も大きな注目を集めています。

今週は波、特に波の重ね合わせと干渉に関して深く学びました。 これらの概念は、量子アルゴリズムの仕組みを理解する上で不可欠なため、まだ十分に理解できない場合は、必要に応じて部分的にもう一度読み直してみてください。


学習を進めていくに当たり、途方にくれたり、興奮したりする時があるかもしれませんが、安心してください、それらの気持ちは当然のものです! 量子コンピューティングは、私たちが日常生活では遭遇することのない現象や考え方を含んでいるため、当然、脳が活発に働くことになるでしょう。

あなたの学習を最大限にサポートするために私たちがついています。それでは 第2週目にまたお会いしましょう!
