Quantum reservoir computing with a single nonlinear oscillator

Understand

Realizing the promise of quantum information processing remains a daunting task, given the omnipresence of noise and error.

• Adapting noise-resilient classical computing modalities to quantum mechanics may be a viable path towards near-term applications in the noisy intermediate-scale quantum era.
• Here, we propose continuous variable quantum reservoir computing in a single nonlinear oscillator.
• Through numerical simulation of our model we demonstrate quantum-classical performance improvement, and identify its likely source: the nonlinearity of quantum measurement.
