Improved entropic uncertainty relations and information exclusion relations
The uncertainty principle can be expressed in entropic terms, also taking into account the role of entanglement in reducing uncertainty. The information exclusion principle bounds instead the… Expand
Entropic uncertainty relations and their applications
Heisenberg’s uncertainty principle forms a fundamental element of quantum mechanics. Uncertainty relations in terms of entropies were initially proposed to deal with conceptual shortcomings in the… Expand
Self-referenced continuous-variable quantum key distribution protocol
We introduce a new continuous-variable quantum key distribution (CV-QKD) protocol, self-referenced CV-QKD, that eliminates the need for transmission of a high-power local oscillator between the… Expand
Reliable numerical key rates for quantum key distribution
TLDR
This work presents a reliable, efficient, and tight numerical method for calculating key rates for finite-dimensional quantum key distribution (QKD) protocols and aims to develop a user-friendly software package that could be used widely by QKD researchers. Expand
Quantum Algorithm Implementations for Beginners
TLDR
This review aims to explain the principles of quantum programming, which are quite different from classical programming, with straightforward algebra that makes understanding of the underlying fascinating quantum mechanical principles optional. Expand
Quantum-assisted quantum compiling
TLDR
This work proposes a variational hybrid quantum-classical algorithm called quantum-assisted quantum compiling (QAQC), and presents both gradient-free and gradient-based approaches to minimizing the cost of this algorithm's cost. Expand
Cost-Function-Dependent Barren Plateaus in Shallow Quantum Neural Networks
TLDR
Two results are rigorously proved that establish a connection between locality and trainability in VQAs and illustrate these ideas with large-scale simulations of a particular VQA known as quantum autoencoders. Expand
Variational Quantum Algorithms
TLDR
An overview of the field of Variational Quantum Algorithms is presented and strategies to overcome their challenges as well as the exciting prospects for using them as a means to obtain quantum advantage are discussed. Expand
Numerical approach for unstructured quantum key distribution
TLDR
A robust numerical approach is developed for calculating the key rate for arbitrary discrete-variable QKD protocols that will allow researchers to study ‘unstructured' protocols, that is, those that lack symmetry. Expand
Two homologous domains of similar structure but different stability in the yeast linker histone, Hho1p.
TLDR
The potential for GII to adopt a structure similar to that of GI when Hho1p is bound to chromatin in vivo suggests that both globular domains might be functional. Expand
