Abstract

Systems, computer-implemented methods, and computer program products to facilitate mapping conditional execution logic to different quantum computing resources are provided. According to an embodiment, a system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise a compiler component that maps a logical reference to a quantum bit data structure in an instruction, to a first engine component, and a deployment component that deploys the first engine component to a first block controller component operatively connected to a first quantum computing resource, wherein the first engine component controls the first quantum computing resource based on the instruction.

First claim

What is claimed is:

1 . A system, comprising:
a memory that stores computer executable components; and a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise:
a compiler component that maps a logical reference to a quantum bit data structure in an instruction, to a first engine component, and
a deployment component that deploys the first engine component to a first block controller component operatively connected to a first quantum computing resource, wherein the first engine component controls the first quantum computing resource based on the instruction.

2 . The system of claim 1 , wherein the first block controller component is operatively connected to a first quantum bit of the first quantum computing resource, and wherein the first engine component controls the first quantum computing resource further based on the first quantum bit.

3 . The system of claim 2 , wherein the first engine component is operatively linked to the first quantum bit via a quantum bit controller coupled to the first quantum bit, wherein the quantum bit controller interfaces with the first quantum bit by sending analog signals to, and receiving analog signals from, the first quantum bit.

4 . The system of claim 2 , wherein the first engine component further conditionally controls the first quantum computing resource based on a value of the first quantum bit.

5 . The system of claim 4 , wherein the compiler component further maps the logical reference of the instruction to a third engine component operatively coupled to a second block controller component of a second quantum computing resource, and wherein the first quantum computing resource and the second quantum computing resource have different structures.

6 . The system of claim 5 , wherein the compiler component selects the third engine component based on second organization data for the second quantum computing resource, wherein the second organization data comprises a structure of engine components of the second quantum computing resource.

7 . The system of claim 1 , wherein, based on the instruction, the deployment component further deploys a second engine component to a second block controller component operatively connected to a second quantum bit of the first quantum computing resource and the first block controller component, wherein the second engine component controls the first quantum computing resource based on the second quantum bit, the first engine component, and the instruction.

8 . The system of claim 7 , wherein, based on first organization data, the compiler component:
further maps execution of the instruction to the first engine component and the second engine component; and configures the first engine component to access a first element of the first quantum computing resource, wherein the first organization data comprises first organization data describing the first element of the first quantum computing resource.

9 . The system of claim 8 , wherein the instruction further comprises an additional logical reference to a register that stores a result of measuring a first quantum bit, and wherein the first element comprises the register.

10 . The system of claim 7 , wherein the first organization data further comprises a latency value corresponding to a duration to complete a communication of a program value between the first block controller component and the second block controller component, and wherein, based on the latency value, the deployment component deploys the second engine component to the second block controller component and the first engine component of the second quantum computing resource component.

11 . The system of claim 7 , wherein, based on the first organization data, the first engine component and the second engine component of the first quantum computing resource are operatively linked to each other in a hierarchical structure.

12 . The system of claim 1 , wherein the deployment component further deploys a fourth engine component to a fourth execution controller component, wherein without mapping by the compiler component, the fourth engine component controls the first quantum computing resource to execute a default instruction.

13 . A computer-implemented method, comprising:
mapping, by a system operatively coupled to a processor, a logical reference to a quantum bit data structure in an instruction, to a first engine component, and deploying, by the system, the first engine component to a first block controller component operatively connected to a first quantum computing resource, wherein the first engine component controls the first quantum computing resource based on the instruction.

14 . The computer-implemented method of claim 13 , further comprising:
deploying, by the system, a second engine component to a second block controller component operatively connected to a second quantum bit of the first quantum computing resource and the first block controller component, wherein the second engine component controls the first quantum computing resource based on the second quantum bit, the first engine component, and the instruction.

15 . The computer-implemented method of claim 14 , further comprising:
further mapping, by the system, based on first organization data, execution of the instruction to the first engine component and the second engine component; and configuring, by the system, the first engine component to access a first element of the first quantum computing resource, wherein the first organization data comprises first organization data describing the first element of the first quantum computing resource.

16 . The computer-implemented method of claim 15 , wherein the instruction further comprises a logical reference to a register that stores a result of measuring a first quantum bit, and wherein the first element comprises the register.

17 . The computer-implemented method of claim 15 , wherein the first organization data further comprises a latency value corresponding to a duration to complete a communication of a program value between the first block controller component and the second block controller component, and wherein, based on the latency value, the deployment component deploys the second engine component to the second block controller component and the first engine component of the second quantum computing resource component.

18 . A computer program product facilitating mapping conditional execution logic to quantum computing resources, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
map, by the processor, a logical reference to a quantum bit data structure in an instruction, to a first engine component, and deploy, by the processor, the first engine component to a first block controller component operatively connected to a first quantum computing resource, wherein the first engine component controls the first quantum computing resource based on the instruction.
