Quantum computing is changing data privacy faster than most legal teams realize. In his latest article, #JoeBartolo explains why Q‑Day will redefine “reasonable security” and why governance is the real priority: legalversemedia.com/quantum-data... #QuantumPrivacy #LegalTech

This research proves perfect privacy is impossible in distributed quantum sensing using Gaussian states. A new 'relative privacy' measure quantifies how much privacy can be achieved while maintaining sensitivity gains in quantum metrology.
