Abstract
A method of mitigating errors when using a quantum computer comprising: performing S101 a first operation (21) on the state of a qubit a plurality of times; wherein the first operation (21) has a first error rate (32); obtaining S102 a first measurement of the average state of the qubit; modifying S103 the error rate of the quantum computer from the first error rate (32) to a second error rate (34); performing S104 a second operation (23) on the state of the qubit a plurality of times; wherein the second operation (23) has the second error rate (34); obtaining S105 a second measurement of the average state of the qubit; modifying S106 the error rate of the quantum computer from the second error rate to a third error rate; performing S107 a third operation on the state of the qubit a plurality of times; wherein the third operation has the third error rate; obtaining S108 a third measurement of the average state of the qubit; modifying S109 the error rate of the quantum computer from the third error rate to a fourth error rate; performing S110 a fourth operation on the state of the qubit a plurality of times; wherein the fourth operation has the fourth error rate; obtaining S111 a fo…
