Quantum processes which do not use coherence
Benjamin Yadin, Jiajun Ma, Davide Girolami +2
A major signature of quantum mechanics beyond classical physics is coherence, the existence of superposition states. The recently developed resource theory of quantum coherence all…
The classical-quantum divergence of complexity in modelling spin chains
Whei Yeap Suen, Jayne Thompson, Andrew J. P. Garner +2
The minimal memory required to model a given stochastic process - known as the statistical complexity - is a widely adopted quantifier of structure in complexity science. Here, we…
Photonic Maxwell's demon
Mihai D. Vidrighin, Oscar Dahlsten, Marco Barbieri +3
We report an experimental realisation of Maxwell's demon in a photonic setup. We show that a measurement at the single-photon level followed by a feed-forward operation allows the…
Converting Coherence to Quantum Correlations
Jiajun Ma, Benjamin Yadin, Davide Girolami +2
Recent results in quantum information theory characterize quantum coherence in the context of resource theories. Here we study the relation between quantum coherence and quantum di…
The power of one qumode for quantum computation
Nana Liu, Jayne Thompson, Christian Weedbrook +4
Although quantum computers are capable of solving problems like factoring exponentially faster than the best-known classical algorithms, determining the resources responsible for t…
Thermodynamics of complexity and pattern manipulation
Andrew J. P. Garner, Jayne Thompson, Vlatko Vedral +1
Many organisms capitalize on their ability to predict the environment to maximize available free energy, and reinvest this energy to create new complex structures. This functionali…
