A system for quantum key synchronization within a server-cluster is provided. The system may include a plurality of silicon-based servers encapsulated in quantum cases. Each quantum case may include a quantum tunneling transmitter module, a quantum random number generator and a quantum entanglement module. The quantum cases may communicate with each other via the quantum tunneling transmitter module or any other suitable manner. The quantum cases may only communicate with cases with which they are entangled. Therefore, in the event of a compromise on one of the servers, the quantum entanglement module, included in the case that encapsulates the compromised server, may become disentangled, and therefore not be able to communicate with the other servers included in the cluster using an internal communications protocol.
