Abstract: Apparatus and method for compiling and executing hybrid classical-quantum programs. For example, one embodiment of a method comprises: reading source code specifying both non-quantum operations to be performed by a host processor and quantum operations to be performed by a quantum accelerator; compiling the source code to generate a target object file, wherein portions of the source code specifying the quantum operations are compiled into quantum basic blocks (QBBs) in the target object file, each QBB comprising one or more quantum instructions to be executed by the quantum accelerator and wherein portions of the source code specifying the non-quantum operations are compiled into native instructions to be executed by the host processor.

Abstract: Apparatus and method including a probabilistic compute element for analyzing measured quantum values and responsively adjusting error correction parameters. For example, one embodiment of an apparatus comprises: a quantum controller to generate physical pulses directed to qubits on a quantum processor in response to operations specified in a quantum runtime; quantum measurement circuitry to measure quantum values associated with the qubits following completion of at least a first cycle of quantum runtime operations; and a probabilistic compute engine to analyze the one or more quantum values using inferencing and to responsively adjust a quantum error correction depth value for minimizing a number of errors to be detected on subsequent cycles of the quantum runtime.

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.

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.
