Detecting lower bounds to quantum channel capacities
Chiara Macchiavello, Massimiliano F. Sacchi
We propose a method to detect lower bounds to quantum capacities of a noisy quantum communication channel by means of few measurements. The method is easily implementable and does…
Efficient superdense coding in the presence of non-Markovian noise
Bi-Heng Liu, Xiao-Min Hu, Yun-Feng Huang +7
Many quantum information tasks rely on entanglement, which is used as a resource, for example, to enable efficient and secure communication. Typically, noise, accompanied by loss o…
Experimental generation of entanglement from classical correlations via non-unital local noise
Adeline Orieux, Mario A. Ciampini, Paolo Mataloni +3
We experimentally show how classical correlations can be turned into quantum entanglement, via the presence of non-unital local noise and the action of a CNOT gate. We first implem…
