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.

Apparatus and method for scalable representations of arbitrary quantum computing rotations. For example, one embodiment of an apparatus comprises: a memory to store a first waveform; and a base envelope generator to implement a base envelope, the base envelope applied to the first waveform to generate a second waveform usable to cause quantum rotation of a specified angle on a target quantum bit (qubit) of a quantum processor, and wherein the base envelope is selected out of a first plurality of envelopes based one or more characteristics specific to the target qubit on which the quantum rotation is performed.

Apparatus and methods for real time calibration of qubits in a quantum processor. For example, one embodiment of an apparatus comprises: a quantum processor comprising a plurality of qubits, each of the qubits having a state; a quantum controller to generate sequences of electromagnetic (EM) pulses to manipulate the states of the plurality of qubits based on a set of control parameters; a qubit measurement unit to measure one or more sensors associated with a corresponding one or more of the qubits of the plurality of qubits to produce one or more corresponding measured values; and a machine-learning engine to evaluate the one or more measured values in accordance with a machine-learning process to generate updated control parameters, wherein the quantum controller is to use the updated control parameters to generate subsequent sequences of EM pulses to manipulate the states of the plurality of qubits.

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.

Apparatus and method for quantum error correction without measurement or active feedback

Apparatus and method for performing a quantum rotation operation. For example, one embodiment of an apparatus comprises: a decoder to decode a plurality of instructions; execution circuitry to execute a first instruction or first set of the instructions to generate a floating point (FP) value and to store the FP value in a first register; the execution circuitry to execute a second instruction or second set of the one or more of the instructions to read the FP value from the first register and compress the FP value to generate a compressed FP value having a precision selected for performing quantum rotation operations; and quantum interface circuitry to process the compressed FP value to cause a quantum rotation to be performed on one or more qubits of a quantum processor.

An example quantum circuit assembly includes a quantum circuit component with a plurality of qubits operable by selectively applying control signals to various terminals of the qubits. The assembly further includes an array of analog memory cells, a DAC configured to sequentially generate analog values/signals to be stored in different ones of the analog memory cells, and a switching arrangement configured to selectively apply control signals to various ones of qubit terminals, where each control signal is applied by the switching arrangement electrically connecting an output terminal of a different analog memory cell of the array of analog memory cells to one of the qubit terminals. Performing digital-to-analog conversion ahead of performing qubit operations and storing results of the conversion in different analog memory cells allows pre-generating and storing analog voltages required for qubit operations that may be carried out during the qubit coherence time.
