Thermal Operations in general are not memoryless
Hanna Wojewódka-ÅciÄ Å¼ko, Maciej Stankiewicz, Edgar A. Aguilar +6
So-called Thermal Operations seem to describe the most fundamental and reasonable set of operations allowable for state transformations at an ambient inverse temperature . Howe…
Benchmarking weak randomness in Quantum and Natural Sources
Maciej Stankiewicz, Roberto Salazar, MikoÅaj Czechlewski +7
Private randomness is a fundamental resource for cryptography, security proofs, and information processing. Quantum devices offer a unique advantage by amplifying weak randomness s…
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…
Entanglement is not sufficient for most practical entanglement-based QKD protocols
Shubhayan Sarkar, Tushita Prasad, Karol Horodecki
Quantum key distribution (QKD) is the most explored application of quantum information theory. A central problem in entanglement-based QKD (EB-QKD), is whether every entangled stat…
