Scientists have found a way of protecting quantum systems against noise using adaptively ‘shaped` pulses of laser light. Quantum systems are notoriously fragile as interactions with their surroundings disturb them - rather like an orchestra trying to stay in tune in a very noisy environment. The stability of quantum systems is essential for any engineering at the quantum level.
