Entanglement Distribution Techniques in Quantum Networks
Quantum entanglement is a unique resource that enables new forms of communication and computation impossible with classical means. Distributing entanglement between distant locations is essential for applications such as quantum key distribution (QKD), quantum teleportation, and connecting quantum computers for…

Can we afford to keep ignoring Open RAN security?
I’m skeptical of ‘futurists’. Work closely enough with the development of technology solutions and you’ll know that the only certain thing about the future is that it’s constantly changing. For example, few ‘futurists’ predicted the Covid-19 outbreak that brought the…

Dynamic Data Masking Protects the View, Not the Model
Masking rewrites what a query returns and leaves the stored data alone. Whoever builds your training set either reads through the mask or under it, and neither outcome gives the resulting model any privacy property at all.

Every Thumbs-Up Can Become a Training Label
Flipping 0.3% of preference labels reached a near-perfect attack success rate against safety alignment. The old defence advice assumes a labelled dataset you can audit, and that is not where labels live now.

Wave Function Collapse: When Quantum Possibilities Become Reality
Wave function collapse is the idea that a quantum system, described by a wave function embodying several possible states at once, suddenly reduces to a single state when observed. In simple terms, before you measure it, a quantum object can…
