Suppressing errors during qubit manipulation invariably demands increased energy expenditure from the controlling device. Calculations reveal this trade-off: achieving higher gate fidelities requires greater entropy production within the macroscopic controller itself. This demonstrates an inherent limit on optimising quantum operations, a constraint previously suspected but now quantified using concrete models.
