It aims to produce large-scale multiphoton graph states with programmable connections, going beyond the limited instances previously demonstrated. The authors position the technique for use in measurement-based quantum computing and quantum repeaters without quantum memories.
OutlookPlausible

The acquisition is intended to combine IonQ's post-quantum cryptography and quantum key distribution capabilities with Elisity's Zero Trust platform. The combined offering aims to address current and future quantum-related security threats.

The work aims to check that both simulators produce consistent and accurate outputs. Both tools are intended for studying quantum network management policies and dynamics under complex noise models.

Cisco's Outshift division has released version 0.2.0 of its Quantum Network Controller and Network-Aware Quantum Compiler for managing multi-node quantum networks. The controller offers on-demand entanglement provisioning across heterogeneous quantum hardware. The compiler integrates circuit compilation, qubit partitioning, and distributed quantum error correction.

Early multi-vendor quantum network testbeds could adopt Cisco's controller as a common orchestration layer for entanglement distribution, reducing the need for bespoke control software.
Researchers at Imperial College London demonstrated hybrid networking protocols that push dependable quantum processor links from the prior d+1 distance-unit limit out to 2d+1 units. The approach also restores perpendicular connectivity from roughly half of d+1 to the full d range. The team frames this as a step toward larger distributed quantum systems where operations are less immediately constrained by loss.

A preprint proposes a scheme for performing distributed lattice surgery between matter-based quantum processors using photonic fusion networks, designed to tolerate photon loss and other link noise stronger than local noise. The work addresses the challenge of implementing logical operations across lossy, probabilistic photonic interconnects.

A new arXiv preprint looks at how the no-cloning theorem constrains quantum secret sharing. It points out that access structures which are easy to realise classically can be ruled out once the shared secret is quantum. The abstract suggests no-cloning may exactly mark the boundary between attainable and unattainable quantum access structures.
OutlookSpeculative
A precise link between no-cloning and quantum access structures could allow protocol designers to rule out impossible quantum secret sharing schemes before implementation, reducing trial and error in early quantum networks.
