我们展示了在测量完成后如何通过数值补偿光电探测和量子态测量中的损失。当总效率超过1/2时，我们的配方适用于所有量子态。然而，对于较小的效率，补偿过程的收敛性取决于所研究的量子态。
We show how losses in photodetection and in quantum-state measurements can be numerically compensated after the measurements have been performed. When the overall efficiency exceeds 1/2, our recipe works for all quantum states. For smaller efficiencies, however, the convergence of the compensation procedure depends on the quantum state under investigation.
