Thermal Operations in general are not memoryless
Hanna Wojewódka-Ściążko, Maciej Stankiewicz, Edgar A. Aguilar +6
So-called Thermal Operations seem to describe the most fundamental and reasonable set of operations allowable for state transformations at an ambient inverse temperature . Howev…
Heat-Bath Algorithmic Cooling with optimal thermalization strategies
Álvaro M. Alhambra, Matteo Lostaglio, Christopher Perry
Heat-Bath Algorithmic Cooling is a set of techniques for producing highly pure quantum systems by utilizing a surrounding heat-bath and unitary interactions. These techniques origi…
All unital qubit channels are -noisy operations
Alexander Müller-Hermes, Christopher Perry
We show that any unital qubit channel can be implemented by letting the input system interact unitarily with a -dimensional environment in the maximally mixed state and then tra…
Entanglement fluctuation theorems
Álvaro M. Alhambra, Lluis Masanes, Jonathan Oppenheim +1
Pure state entanglement transformations have been thought of as irreversible, with reversible transformations generally only possible in the limit of many copies. Here, we show tha…
Elementary Thermal Operations
Matteo Lostaglio, Álvaro M. Alhambra, Christopher Perry
To what extent do thermodynamic resource theories capture physically relevant constraints? Inspired by quantum computation, we define a set of elementary thermodynamic gates that o…
Clean quantum and classical communication protocols
Harry Buhrman, Matthias Christandl, Christopher Perry +1
By how much must the communication complexity of a function increase if we demand that the parties not only correctly compute the function but also return all registers (other than…
A sufficient set of experimentally implementable thermal operations
Chris Perry, Piotr Ćwikliński, Janet Anders +2
Recent work using tools from quantum information theory has shown that at the nanoscale where quantum effects become prevalent, there is not one thermodynamical second law but many…
Doubly infinite separation of quantum information and communication
Zi-Wen Liu, Christopher Perry, Yechao Zhu +2
We prove the existence of (one-way) communication tasks with a subconstant versus superconstant asymptotic gap, which we call "doubly infinite," between their quantum information a…
What is the probability of a thermodynamical transition?
Álvaro M. Alhambra, Jonathan Oppenheim, Christopher Perry
If the second law of thermodynamics forbids a transition from one state to another, then it is still possible to make the transition happen by using a sufficient amount of work. Bu…
Communication tasks with infinite quantum-classical separation
Christopher Perry, Rahul Jain, Jonathan Oppenheim
Quantum resources can be more powerful than classical resources - a quantum computer can solve certain problems exponentially faster than a classical computer, and computing a func…
Conclusive Exclusion of Quantum States
Somshubhro Bandyopadhyay, Rahul Jain, Jonathan Oppenheim +1
In the task of quantum state exclusion we consider a quantum system, prepared in a state chosen from a known set. The aim is to perform a measurement on the system which can conclu…
