Abstract
A method of mitigating errors when using a quantum computer comprising: performing Sa first operation () on the state of a qubit a plurality of times; wherein the first operation () has a first error rate (); obtaining Sa first measurement of the average state of the qubit; modifying Sthe error rate of the quantum computer from the first error rate () to a second error rate (); performing Sa second operation () on the state of the qubit a plurality of times; wherein the second operation () has the second error rate (); obtaining Sa second measurement of the average state of the qubit; modifying Sthe error rate of the quantum computer from the second error rate to a third error rate; performing Sa third operation on the state of the qubit a plurality of times; wherein the third operation has the third error rate; obtaining Sa third measurement of the average state of the qubit; modifying Sthe error rate of the quantum computer from the third error rate to a fourth error rate; performing Sa fourth operation on the state of the qubit a plurality of times; wherein the fourth operation has the fourth error rate; obtaining Sa fourth measurement of the average state of the qubit; fitting Sthe first, second, third and fourth measurements to a multi-exponential decay curve (); and extrapolating Sthe average state of the qubit at a fifth error rate () using the fitted curve (), wherein the fifth error rate () is lower than the first, second, third and fourth error rates.
