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…

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…

Cat Qubits 101
Bosonic “cat qubits” are quantum bits encoded in the states of bosonic oscillators (e.g. modes of a microwave cavity) that resemble Schrödinger’s famous alive/dead cat superposition. Instead of relying on a single two-level quantum element, a cat qubit stores information…
