About this episode
A quantum computer has performed a calculation considered impossible for conventional computers, but how meaningful is the result? As our guest reveals, this quantum state can be hugely significant and garbage – at the same time.
Also we look at a new method of gene editing, which avoids cutting up DNA, get to grips with where the worlds worms live and watch elements being created in distant solar collisions.
