Markets are currently fearful (Fear & Greed 27) and risk-off, so esoteric scientific news is ignored. However, for crypto investors, each step toward practical quantum control increases the urgency for quantum-resistant cryptography standards. This particular result—boosting nonlinear tunnelling with squeezed vacuum—is a niche but real step in quantum manipulation.

Bright squeezed vacuum light boosts nonlinear atomic tunnelling ionization more than 20-fold compared with coherent light, enabling quantum control without increasing classical intensity.
