Overview

Q-READY provides a systematic methodology for predicting whether a given computational problem can benefit from quantum acceleration and how to optimally partition workloads between classical and quantum processors. As quantum computing transitions from research to practical infrastructure, this framework addresses the critical gap between theoretical quantum advantage and real-world application feasibility.

Core Methodology

1. Quantum Readiness Assessment

Assess problem characteristics against quantum advantage criteria:

• Problem Structure: Does the problem map to known quantum algorithms (QAOA, VQE, HHL, quantum simulation)?
• Instance Size: Is the problem size large enough that classical methods are struggling but small enough for NISQ-era quantum processors?
• Error Tolerance: Can the application tolerate NISQ-level noise, or does it require fault-tolerant quantum computation?
• Data Encoding: Is there an efficient quantum data encoding strategy available?
• Classical Baseline: What is the best classical algorithm's performance? Is there a proven quantum speedup?

2. Hybrid Partitioning Strategy

Decompose the computational workflow into quantum and classical components:

• Quantum-Suitable Subproblems: Identify subproblems that benefit from quantum properties (superposition, entanglement, interference)
• Classical Pre/Post-Processing: Data preparation, feature engineering, result interpretation, error mitigation
• Interface Design: Define data exchange formats and synchronization points between quantum and classical processors
• Iterative Refinement: Design feedback loops where classical optimization adjusts quantum circuit parameters

3. Feasibility Prediction Model

Use structured evaluation criteria:

Criterion	Score (1-5)	Description
Algorithm Mapping		Direct mapping to known quantum algorithms
Noise Resilience		Tolerance to NISQ-era errors
Encoding Efficiency		Overhead of classical-to-quantum data loading
Classical Competition		Gap between classical best and potential quantum
Infrastructure Access		Availability of quantum hardware/simulators
Total Score	≥15	Quantum-feasible; 10-14: Monitor; <10: Not feasible

Practical Checklist

When to Consider Q-READY

• Problem involves combinatorial optimization with many constraints
• Classical simulation is hitting computational limits
• Problem has known quantum algorithm mapping
• Team has access to quantum hardware or cloud quantum services
• Application can tolerate current quantum noise levels
• Data encoding overhead is manageable

When to Wait

• Classical algorithms are improving rapidly (e.g., tensor networks)
• Problem size exceeds near-term quantum capacity
• Noisy intermediate-scale results are insufficient for the use case
• Classical baseline already meets performance requirements
• No efficient quantum data loading strategy exists

Key Insights from Research

1. Predictive Assessment Over Reactive Experimentation: Q-READY shifts from "try quantum and see" to systematic feasibility prediction before resource investment.

2. Software Engineering Integration: First framework explicitly designed for software engineering workflows, not just algorithm research.

3. Hybrid-First Approach: Assumes quantum will augment, not replace, classical computation in the near-to-medium term.

4. Domain-Specific Criteria: Feasibility varies significantly by domain — what works for chemistry may not apply to software testing.

5. Evolving Threshold: Quantum feasibility thresholds shift as both quantum hardware improves and classical algorithms advance.

Pitfalls

• Overestimating Near-Term Quantum Advantage: NISQ devices have severe limitations; don't ignore noise and qubit count constraints
• Ignoring Classical Competition: Classical algorithms continue to improve (tensor networks, approximation algorithms)
• Data Loading Bottleneck: Quantum state preparation can dominate total runtime
• Benchmarking Bias: Compare against optimized classical baselines, not naive implementations
• Hardware Access Constraints: Cloud quantum computing has queue times and cost considerations
