Barcoding photons can provide a host of functionalities that could benefit future quantum communication systems and networks beyond today's imagination. As significant application barcoding photons, we introduce code division multiple-access (CDMA) for various applications. In this context, discuss the fundamental principles novel CDMA (QCDMA) technique based on spectrally encoding decoding con...

Quantum communication provides an absolute security advantage, and it has been widely developed over the past 30 years. As an important branch of quantum communication, quantum secure direct communication (QSDC) promotes high security and instantaneousness in communication through directly transmitting messages over a quantum channel. The full implementation of a quantum protocol always require...

We consider a variation of the multi-party communication complexity scenario where the parties are supplied with an extra resource: particles in an entangled quantum state. We show that, although a prior quantum entanglement cannot be used to simulate a communication channel, it can reduce the communication complexity of functions in some cases. Specifically, we show that, for a particular func...
