1. A method for mitigating errors in measurements from a quantum system, the method comprising:
training a discriminator to classify measurements of quantum states of qubits as corresponding to a first quantum state or a second quantum state;
defining a first region of trust based on a first discriminator boundary and a second region of trust based on a second discriminator boundary corresponding to trusted measurements of said first quantum state and said second quantum state, respectively, using said trained discriminator;
receiving a measurement result of a qubit state; and
rejecting said measurement result in response to not being located within said first region of trust or said second region of trust.
