Calculation with electron spins in a quantum computer assumes that the spin states last for a sufficient period of time. Physicists have now demonstrated that electron exchange in quantum dots fundamentally limits the stability of this information. Control of this exchange process paves the way for further progress in the coherence of the fragile quantum states.
