Qubit Reservation Service for Quantum Computing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In quantum computing systems, qubits are a finite resource, and multiple applications may concurrently require them, leading to potential failures or non-execution of quantum applications due to unavailability of qubits at the time of execution, as users lack real-time information on qubit availability.
Innovation Solution
A qubit reservation service that allows users to reserve qubits in advance for future execution, ensuring that reserved qubits are allocated exclusively to the reserving application, and are returned to the pool upon termination, thereby guaranteeing resource availability when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If qubits are allocated on a first-come, first-served basis, then the system is simple to operate, but quantum applications may fail to execute due to unavailability of qubits
Solution Approach 1:
The patent implements a reservation system where users can reserve qubits in advance before they are needed for quantum application execution. This preliminary action ensures that qubits are secured ahead of time, preventing execution failures due to unavailability while maintaining a relatively simple allocation mechanism through metadata tracking.
2Reliability
If qubits are reserved in advance, then qubit availability is guaranteed for the reserving application, but other applications cannot access the reserved qubits during the reservation period
Solution Approach 1:
The reservation system allows applications to secure qubits in advance, guaranteeing availability for the reservation period. The system tracks reserved qubits through metadata and ensures exclusive access during the reservation timeframe, while automatically releasing qubits when the reservation expires or the application terminates.
Solution Approach 2:
The system maintains metadata that continuously tracks the reservation status of qubits, providing feedback to both reserving and other applications about qubit availability. This feedback mechanism enables the system to manage resource allocation dynamically while ensuring guaranteed availability for reserved applications.
3Productivity
If users can reserve qubits for future execution, then quantum applications can be scheduled with guaranteed resource availability, but the system requires tracking and managing reservation metadata
Solution Approach 1:
The system enables advance reservation of qubits for future quantum application execution, allowing users to schedule applications with guaranteed resource availability. This preliminary reservation action improves execution efficiency by ensuring resources are ready when needed, while the system manages the associated metadata through structured tracking mechanisms.

AI summary
Qubit reservation is disclosed. A first request to reserve at least one qubit is received from a requestor. The first request includes an application identifier (ID) of a first quantum application. Qubit metadata that describes characteristics of a first plurality of qubits implemented by a first quantum computing system is accessed to identify a first qubit that is available to be reserved. The qubit metadata is modified to reserve the first qubit to thereby inhibit access to the first qubit by any quantum application other than the first quantum application.
