Correcting The Counts

Single-qubit readout calibration on a device:

prepared measured 0 measured 1
∣0⟩\lvert 0\rangle 0.97 0.03
∣1⟩\lvert 1\rangle 0.08 0.92

You run a circuit for 10,000 shots and observe 4,000 counts of 1.

Treating the observed distribution as A ptrueA,p_{\text{true}} with A=(0.970.080.030.92)A = \begin{pmatrix} 0.97 & 0.08 \ 0.03 & 0.92 \end{pmatrix}, what is the corrected estimate of P(1)P(1)?

A

0.3700.370

B

≈0.416\approx 0.416

C

0.4000.400

D

≈0.435\approx 0.435
