Abstract: Apparatus and method for measurement-free (MF) quantum error correction (QEC). For example, one embodiment of a method comprises: determining an error syndrome on a first subset of ancilla qubits of a quantum processor; decoding the error syndrome to produce decoded results on a second subset of ancilla qubits of the quantum processor; applying the decoded results to one or more system qubits; and unconditionally resetting the first subset and/or second subset of ancilla qubits to remove entropy and/or noise from the quantum system, wherein the operations of determining the error syndrome, decoding the error syndrome, applying the error syndrome, and unconditionally resetting the first and/or second subset of ancilla qubits are performed responsive to a qubit controller executing quantum control instructions provided from or derived from a script and without transmitting measurement data related to the error syndrome to a non-quantum computing device.

Abstract: Apparatus and method for quantum drift compensation. For example, one embodiment of a quantum system comprises: a quantum processor comprising one or more data quantum bits (qubits) and one or more ancilla qubits; a quantum controller to control the qubits responsive to a quantum runtime; an error detector to detect errors in the qubits; a quantum drift compensator to determine a current system drift for the quantum processor based on the errors and to responsively generate a set of compensation values if the current system drift is determined to be above a threshold.
