Quantum machine learning for quantum anomaly detection
Nana Liu, Patrick Rebentrost
Anomaly detection is used for identifying data that deviate from `normal' data patterns. Its usage on classical data finds diverse applications in many important areas like fraud d…
Continuous-variable quantum key distribution in fast fading channels
Panagiotis Papanastasiou, Christian Weedbrook, Stefano Pirandola
We investigate the performance of several continuous-variable quantum key distribution protocols in the presence of fading channels. These are lossy channels whose transmissivity c…
Continuous-variable QKD over 50km commercial fiber
Yi-Chen Zhang, Zhengyu Li, Ziyang Chen +18
The continuous-variable version of quantum key distribution (QKD) offers the advantages (over discrete-variable systems) of higher secret key rates in metropolitan areas as well as…
Continuous-variable quantum Gaussian process regression and quantum singular value decomposition of non-sparse low rank matrices
Siddhartha Das, George Siopsis, Christian Weedbrook
With the significant advancement in quantum computation in the past couple of decades, the exploration of machine-learning subroutines using quantum strategies has become increasin…
A novel approach to perturbative calculations for a large class of interacting boson theories
Kamil Bradler
We present a method of calculating the interacting S-matrix to an arbitrary perturbative order for a large class of boson interaction Lagrangians. The method takes advantage of a p…
