Quantum waste management: Utilizing residual states in quantum information processing
Karol Horodecki, Chirag Srivastava, Leonard Sikorski +1
Quantum resource theories use distillation protocols to convert less resourceful states into fully resourceful ones. However, these protocols often also generate an additional, unu…
Cost of quantum secret key
Karol Horodecki, Leonard Sikorski, Siddhartha Das +1
In this paper, we develop the resource theory of quantum secret key. Operating under the assumption that entangled states with zero distillable key do not exist, we define the key…
Limitations on quantum key repeaters for all key correlated states
Leonard Sikorski, Karol Horodecki, Åukasz Pawela
Quantum key repeater is the backbone of the future Quantum Internet. It is an open problem to determine, for an arbitrary mixed bipartite state shared between the stations of a qua…
Quantification of the energy consumption of entanglement distribution
Karol Horodecki, Marek Winczewski, Leonard Sikorski +3
Inspired by environmental sciences, we develop a framework to quantify the energy needed to generate quantum entanglement via noisy quantum channels, focusing on the hardware-indep…
