    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 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.
