わたしたちの直感に反する量子力学の法則に従う粒子の集合「量子システム」を研究するのは容易ではない。量子論の土台であるハイゼンベルクの不確定性原理によれば、ある粒子の正確な位置と速度を同時に測定することは不可能だという。それがわからなければ、極めて重要な情報にもかかわらず、何が起きているか理解できない。 例えばある特定の電子の集合を研究するとき、研究者たちはあらゆることを考慮し実験に臨まなくてはならない。その実験は言ってみれば、電子を入れた箱にさまざまな刺激を与え、最終的にどんな様子になったかスナップショットを撮って記録するようなものだ。そうすることで、内部に働いている量子的な動きを見極めようというわけだ。...

It’s not easy to study quantum systems—collections of particles that follow the counterintuitive rules of quantum mechanics. Heisenberg’s uncertainty principle, a cornerstone of quantum theory, says it’s impossible to simultaneously measure a particle’s exact position and its speed—pretty important information for understanding what’s going on. In order to study, say, a particular collection of electrons, researchers have to be clever about it.

In February 2023, Google’s artificial intelligence chatbot Bard claimed that the James Webb Space Telescope had captured the first image of a planet outside our solar system. It hadn’t. When researchers from Purdue University asked OpenAI’s ChatGPT more than 500 programming questions, more than half of the responses were inaccurate.

Introduction If you’ve been making the same commute for a long time, you’ve probably settled on what seems like the best route. But “best” is a slippery concept. Perhaps one day there’s an accident or road closure, and your fastest route becomes the slowest. Scenarios like this are also a challenge for researchers who develop algorithms, the step-by-step procedures that computers use to solve problems.

The global population continues to face the detrimental effects of food insecurity and climate change, with an estimated 1.3 billion people having experienced food insecurity in 2022 [4]. At the 2023 United Nations Climate Change Conference (COP28)—which took place last December in Dubai, the United Arab Emirates (UAE)—more than 150 countries endorsed the COP28 UAE Declaration on Sustainable Agriculture, Resilient Food Systems, and Climate Action.
