QuantumComm Workbench

Quantum communication tools from photon link to network scenario.

A browser-based workbench for cautious QKD estimates, protocol learning, mock key-delivery integration, and quantum-network scenario exploration.

Main sections

Learn

Protocol explainers and compact interactive demos.

Tools

Engineering calculators, API mocks, standards checks, and reports.

Networks

Scenario builder, routing, repeater optimization, and benchmarks.

Resources

Curated simulators, standards, protocols, and model cautions.

Flagship workflow

A complete MVP path from optical link assumptions to application key consumption and network scenario export.

QKD Engineering Lab

Combine link budget, QBER, post-processing, and risk proxies.

API/KMS Sandbox

Request demo-only keys, watch exhaustion, and simulate consumption.

Scenario Builder

Import, validate, and export quantum-network topology JSON.
