Uniqueness of quantum state over time function
Seok Hyung Lie, Nelly H. Y. Ng
A fundamental A fundamental asymmetry exists within the conventional framework of quantum theory between space and time, in terms of representing causal relations via quantum chann…
Catalysis in Quantum Information Theory
Patryk Lipka-Bartosik, Henrik Wilming, Nelly H. Y. Ng
Catalysts open up new reaction pathways that can speed up chemical reactions while not consuming the catalyst. A similar phenomenon has been discovered in quantum information scien…
Catalysis always degrades external quantum correlations
Seok Hyung Lie, Nelly H. Y. Ng
Catalysts used in quantum resource theories need not be in isolation and therefore are possibly correlated with external systems, which the agent does not have access to. Do such c…
A hierarchy of thermal processes collapses under catalysis
Jeongrak Son, Nelly H. Y. Ng
Thermal operations are a generic description for allowed state transitions under thermodynamic restrictions. However, the quest for simpler methods to encompass all these processes…
Catalysis in Action via Elementary Thermal Operations
Jeongrak Son, Nelly H. Y. Ng
We investigate catalysis in the framework of elementary thermal operations, leveraging the distinct features of such operations to illuminate catalytic dynamics. As groundwork, we…
The variance of relative surprisal as single-shot quantifier
Paul Boes, Nelly H. Y. Ng, Henrik Wilming
The variance of (relative) surprisal, also known as varentropy, so far mostly plays a role in information theory as quantifying the leading order corrections to asymptotic i.i.d.~l…
Quantum field thermal machines
M. Gluza, J. Sabino, N. H. Y. Ng +7
Recent years have enjoyed an overwhelming interest in quantum thermodynamics, a field of research aimed at understanding thermodynamic tasks performed in the quantum regime. Furthe…
Bounding the resources for thermalizing many-body localized systems
Carlo Sparaciari, Marcel Goihl, Paul Boes +2
Understanding under which conditions physical systems thermalize is a long-standing question in many-body physics. While generic quantum systems thermalize, there are known instanc…
By-passing fluctuation theorems
Paul Boes, Rodrigo Gallego, Nelly H. Y. Ng +2
Fluctuation theorems impose constraints on possible work extraction probabilities in thermodynamical processes. These constraints are stronger than the usual second law, which is c…
Resource theory of quantum thermodynamics: Thermal operations and Second Laws
Nelly Ng, Mischa P. Woods
Resource theories are a generic approach used to manage any valuable resource, such as entanglement, purity, and asymmetry. Such frameworks are characterized by two main elements:…
Quantum work statistics and resource theories: bridging the gap through Renyi divergences
G. Guarnieri, N. H. Y. Ng, K. Modi +3
The work performed on or extracted from a non-autonomous quantum system described by means of a two-point projective-measurement approach takes the form of a stochastic variable. W…
Smoothed generalized free energies for thermodynamics
Remco van der Meer, Nelly Huei Ying Ng, Stephanie Wehner
In the study of thermodynamics for nanoscale quantum systems, a family of quantities known as generalized free energies have been derived as necessary and sufficient conditions tha…
The maximum efficiency of nano heat engines depends on more than temperature
Mischa P. Woods, Nelly Ng, Stephanie Wehner
Sadi Carnot's theorem regarding the maximum efficiency of heat engines is considered to be of fundamental importance in thermodynamics. This theorem famously states that the maximu…
Limits to catalysis in quantum thermodynamics
Nelly Huei Ying Ng, Laura Mančinska, Cristina Cirstoiu +2
Quantum thermodynamics is a research field that aims at fleshing out the ultimate limits of thermodynamic processes in the deep quantum regime. A complete picture of quantum thermo…
The second laws of quantum thermodynamics
Fernando G. S. L. Brandao, Michał Horodecki, Nelly Huei Ying Ng +2
The second law of thermodynamics tells us which state transformations are so statistically unlikely that they are effectively forbidden. Its original formulation, due to Clausius,…
Experimental implementation of bit commitment in the noisy-storage model
Nelly Huei Ying Ng, Siddarth Koduru Joshi, Chen Ming Chia +2
Fundamental primitives such as bit commitment and oblivious transfer serve as building blocks for many other two-party protocols. Hence, the secure implementation of such primitive…
A min-entropy uncertainty relation for finite size cryptography
Nelly Huei Ying Ng, Mario Berta, Stephanie Wehner
Apart from their foundational significance, entropic uncertainty relations play a central role in proving the security of quantum cryptographic protocols. Of particular interest ar…
