What IBM's result means for quantum computing

In this episode:00:47 How to make quantum computers ready for real world applicationsQuantum computers have long held the promise of being able to perform tasks that classical computers can’t. However, despite this promise, there have been few applications that can only be accomplished by a quantum computer. Now though, researchers show that a quantum computer can resolve a physics problem concerning the orientation of quantum particles in a 2D material, which is difficult to accomplish with a ‘regular’ machine. They hope that this shows how quantum computers could be applied in real world research applications in the near future.Nature News: IBM quantum computer passes calculation milestoneResearch article: Kim et al.News and Views: Quantum computer scales up by mitigating errors10:11 Research HighlightsHow some bacteria turned their defences into weapons, and a forecast of how quickly arctic sea ice will disappear.Research Highlight: Cholera bacteria turn slime into an offensive weaponResearch Highlight: The Arctic could go ice-free in less than a decade12:45 How psychedelics might work in the brainPsychedelics are a group of drugs that affect perceptions of consciousness, and are of increasing interest in the treatment of conditions like depression, post-traumatic stress disorder, and addiction. However, a lot is unknown about how they affect the brain. Now, researchers have shown that these varied drugs may have a shared mechanism: making the brain more able to forge new connections between synapses. They hope that this will inform how best to use psychedelics in treatments.Research article: Nardou et al.News and Views: Timing is key for behavioural benefits of psychedelics20:17 Briefing ChatWe discuss some highlights from the Nature Briefing.
