The unit that runs your microwave, your phone and the Radio 4 pips is up for review, and the clocks that would replace it are so precise they can spot a centimetre of altitude. A trip to Teddington to ask what 'accurate' even means when the universe refuses to hold still.
It is the fanciest fridge in the country and it contains no milk. We go inside the dilution refrigerators at British quantum labs to explain millikelvin cooling in plain English, count the electricity bills, and ask whether the UK has enough cryogenic engineers to keep the qubits shivering.
Empty space is not an empty bowl. In quantum field theory it is a simmering broth of fields, fluctuations and mathematical bubbles. We dunk a ladle into what 'quantum soup' actually means, visit the UK labs trying to cook with it, and serve a sceptical sidebar on the difference between real quantum weirdness and marketing garnish.
Can a plate of eggs, beans, bacon and toast explain superposition, entanglement and decoherence? Probably not literally — but it makes a cracking breakfast briefing. Pull up a chair at the quantum caff.
