Nonlocal and quantum advantages in network coding for multiple access channels
Jiyoung Yun, Seung-Hyun Nam, Hyun-Young Park +3
In this work, we consider two-sender, one-receiver communication over a discrete memoryless multiple-access channel without feedback, where two senders may cooperate on channel cod…
Feature Map for Quantum Data in Classification
Hyeokjea Kwon, Hojun Lee, Joonwoo Bae
The kernel trick in supervised learning signifies transformations of an inner product by a feature map, which then restructures training data in a larger Hilbert space according to…
On the structure of mirrored operators obtained from optimal entanglement witnesses
Anindita Bera, Joonwoo Bae, Beatrix C. Hiesmayr +1
Entanglement witnesses (EWs) are a versatile tool in the verification of entangled states. The framework of mirrored EW doubles the power of a given EW by introducing its twin -- a…
Maximum confidence measurement for qubit states
Hanwool Lee, Kieran Flatt, Carles Roch i Carceller +2
In quantum state discrimination, one aims to identify unknown states from a given ensemble by performing measurements. Different strategies such as minimum-error discrimination or…
Quantum vs. noncontextual semi-device-independent randomness certification
Carles Roch I Carceller, Kieran Flatt, Hanwool Lee +2
We compare the power of quantum and classical physics in terms of randomness certification from devices which are only partially characterised. We study randomness certification ba…
Contextual advantages and certification for maximum confidence discrimination
Kieran Flatt, Hanwool Lee, Carles Roch i Carceller +2
One of the most fundamental results in quantum information theory is that no measurement can perfectly discriminate between non-orthogonal quantum states. In this work, we investig…
