Since you clearly know more than me what your talking about, is it correct to interpret the significance of china's quantum satellite communication as one of quantum cryptography (based on states changing post measurement) rather than potential high speed communication?
- roywiggins 5y agoThere's quantum superdense coding, which in theory could allow higher bandwidth (transmitting one qbit can be used to transmit two classical bits) but I believe the main point of quantum channels is for cryptography. If entanglement allowed FTL communication you'd see high-frequency traders already using it!
