Quantum and coherent signal transmission on a single-frequency channel via the electro-optic serrodyne technique - publication
2024-07-26
Scientists have transmitted quantum and conventional internet data through the same fiber-optic channel, meaning a future quantum internet could theoretically use existing infrastructure.
Scientists have successfully transmitted quantum data and conventional data through a single optical fiber for the first time. The research demonstrates that quantum data in the form of entangled photons and conventional internet data sent as laser pulses can coexist in the same fiber-optic cable. Most research into building a quantum internet has focused on the need for separate infrastructure or dedicated channels for quantum data to avoid interference from “classical” data. But this new “hybrid” network could pave the way for more efficient implementation of quantum communications by enabling quantum and conventional data to share the same infrastructure. The researchers revealed their findings in a study published July 26 in the journal Science Advances.

Entangling Independent Particles by Path Identity - publication
2024-12-02
In the study ‘Entangling Independent Particles by Path Identity‘ scientists used PyTheus, an AI tool that has been specifically created for designing quantum-optic experiments.
The authors of the paper initially set out to reproduce established protocols for entanglement swapping in quantum communications. However, the AI tool kept producing a much simpler method to achieve quantum entanglement of photons. When particles such as photons become entangled, they can share quantum properties — including information — regardless of the distance between them. This phenomenon is important in quantum physics and is one of the features that makes quantum computers so powerful. But the bonds of quantum entanglement have typically proven challenging for scientists to form. This is because it requires the preparation of two separate entangled pairs, then measuring the strength of entanglement — called a Bell-state measurement — on a photon from each of the pairs. These measurements cause the quantum system to collapse and leave the two unmeasured photons entangled, despite them never having directly interacted with one another. This process of “entanglement swapping” could be used for quantum teleportation.

Quantum Computing Military 2026: The Race for Unhackable.
The dominant narrative about quantum computing is about breaking encryption. Shor’s algorithm, the RSA threat, the cryptopocalypse — the story has been told so many times it has acquired the comfort of familiarity. Nation-states are racing to build a quantum computer capable of breaking RSA-2048. Whoever gets there first reads everyone’s old messages. This is a real threat. It is also the distraction. The more consequential race is happening on the other side of the physics. Not quantum computing for breaking encryption, but quantum communication for creating encryption so perfect it is mathematically impossible to intercept without detection. The technology is quantum key distribution, and the three nations building operational military networks around it — China, the United States, and a lesser-known European consortium — are constructing a strategic advantage that, once established, cannot be reversed.
