  We present methods for evaluating the rate of change in quantities during
quantum evolution due to coupling to the environment (dissipation hereafter).
The protocol is based on repeating a given quantum circuit (or quantum
operation) twice, thrice, and so on, and measuring an expectation value after
each number of repetitions. We start by applying this method for measuring the
rate of purity changes in quantum circuits. This provides direct information on
the quality of the circuit. Furthermore, the presented scheme enables to
distill the dissipative contribution in the changes of quantities such as
energies and coherence. In particular, this can be applied to the local
Hamiltonians of specific qubits. Thus, our approach can be used to locate
"hotspots" where the dissipation takes place. A variant of this method can be
used to measure the entanglement buildup in quantum circuits. These methods are
scalable as they involve only a few observables which are relatively easy to
measure in NISQ devices.
