A new protocol demonstrating quantum enhanced robustness to noise has been implemented by the Quantum Photonics Lab
The novel scheme requires only one additional bit of data and entanglement to dramatically increase the data recovery probability.
When a single data bit is transmitted, the success probability is experimentally enhanced by over 20%.
Furthermore, when a two-bit message is transmitted, the enhancement is over 50% compared to optimal clasical protocol.
These key results have recently been published in Physical Review A.
