1. A computer-implemented method for quantum-safe quantum streaming of data items from a first endpoint device to a second endpoint device via a server of a quantum cloud platform, the method, performed at the first endpoint device, comprising:
splitting a data item into a plurality of data shards that allow reconstruction of the data item;
encrypting each of the data shards separately using a first cryptographic key,
wherein the first cryptographic key is shared between the first endpoint device and the second endpoint device;
establishing a series or a first plurality of secure channels with a server of a quantum cloud platform using a second cryptographic key,
wherein the second cryptographic key is shared between the endpoint and the server; and
transmitting the plurality of encrypted shards towards the second endpoint device via the server over the series or plurality of secure channels.
