What the article says around this equation

No question about a “computational advantage” is well posed until an actor states which clock it is asking about and which currency it is spending. Three candidate rates exist, and they are not interchangeable: operations per unit of the processor’s own proper time τ\tau ; operations per unit of the distant bookkeeper’s coordinate time t ; and operations per unit of energy actually invested, measured in whichever frame that energy was paid from. A fourth candidate, operations per bit irreversibly erased, belongs to Landauer’s accounting rather than to the quantum speed limit and is treated separately near the end of this piece [ 6 ] .
