Noise-Enhanced Quantum Kernels

Description

Quantum kernel method implementation for analog quantum computers with noise-enhanced performance characteristics.

Core Concepts

Analog Quantum Kernel

• Constructed for analog quantum computing platforms
• Alternative to gate-based quantum circuits
• Competitive against classical kernel methods

Hybrid Quantum Kernel

• Combines analog and digital elements
• Suitable for benchmarking tasks
• Applications in non-Markovianity estimation

Noise-Enhanced Performance

• Operational noise improves kernel performance
• Mechanism: improved expressivity and model complexity
• Counterintuitive beneficial effect of noise

Applications

Benchmarking Tasks

• Performance comparison with classical kernels
• Validation on standard datasets

Non-Markovianity Estimation

• Estimating non-Markovianity from sparse data
• Practical quantum machine learning problem
