Abstract
A feedback controller is provided to generate a quantum feedback operation to control one or more ancilla qubits in a quantum error correcting code. The quantum feedback operation is based on the measurement of the one or more ancilla qubits. The feedback controller is operable to dynamically adjust a state discrimination according to previous measurements of the one or more ancilla qubits.
Claims21
1-40. (canceled)
A system, comprising:
- a controller configured to generate a quantum feedback operation according to one or more ancilla qubits in a quantum error correcting code, wherein the quantum feedback operation is configured to increase a likelihood that the one or more ancilla qubits will subsequently be measured in a predetermined state.
A method, comprising:
- via a quantum controller:
- measuring one or more ancilla qubits in a quantum error correcting code;
- generating a quantum feedback operation according to the one or more ancilla qubits, wherein the quantum feedback operation is configured to increase a likelihood that the one or more ancilla qubits will subsequently be measured in a predetermined state;
- applying the quantum feedback operation;
- and
- subsequently measuring the one or more ancilla qubits.
