Fig.1 Schematic of the experimental setup for continuous-variable entanglement-assisted quantum comumication. Alice encodes classical signals on the ancilla beam by an amplitude modulator (AM) and a ...

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, ...

Dense coding is arguably the protocol that launched the field of quantum communication. Today, however, more than a decade after its initial experimental realization, the channel capacity remains ...

The quantum low-density parity check (QLDPC) codes, the “holy grail” of quantum error correction research and development for 30 years, have a breakthrough ...
