Even in the presence of conservation laws, one can perform arbitrary transformations on a system if given access to a suitable reference frame, since conserved quantities may be exchanged between the system and the frame. Here we explore whether these quantities can be separated into different parts of the reference frame, with each part acting as a "battery" for a distinct quantity. For systems composed of spin-1/2 particles, we show that the components of angular momentum S_{x}, S_{y}, and S_… Expand
Transformation of Spin in Quantum Reference Frames
In physical experiments, reference frames are standardly modelled through a specific choice of coordinates used to describe the physical systems, but they themselves are not considered as such.Expand
Resource theory of heat and work with non-commuting charges: yet another new foundation of thermodynamics
A resource theory of thermodynamics of asymptotically many non-interacting systems with multiple conserved quantities or charges is formulated and it is shown that the optimal bath rate, as a function of how tightly the second law is attained, can be expressed in terms of the heat capacity of the bath.

Quantum Thermodynamics Allows Quantum Measurement Almost Without Collapse
We introduce a quantum measurement process that is capable of characterizing an unknown state of a system almost without disturbing or collapsing it. The underlying idea is to extract information ofExpand
From Quantum Source Compression to Quantum Thermodynamics
This thesis addresses problems in the field of quantum information theory, specifically, quantum Shannon theory with a resource theory point of view of a quantum system with multiple non-commuting charges where the objects and allowed operations are thermodynamically meaningful. Expand

Quantum reference frames and their applications to thermodynamics
We construct a quantum reference frame, which can be used to approximately implement arbitrary unitary transformations on a system in the presence of any number of extensive conserved quantities, byExpand
Noncommuting conserved charges in quantum many-body thermalization.
This work introduces noncommuting conserved quantities from QI-theoretic thermodynamics into quantum many-body physics: atomic, molecular, and optical physics and condensed matter. Expand
Thermodynamics of quantum systems with multiple conserved quantities
This work presents explicit protocols that allow us to perform arbitrarily good trade-offs and extract arbitrarily good combinations of conserved quantities from individual quantum systems. Expand
Microcanonical and resource-theoretic derivations of the thermal state of a quantum system with noncommuting charges
This work defines a resource-theory model for thermodynamic exchanges of noncommuting observables and investigates the thermal state of the grand canonical ensemble, which is expected to be the equilibrium point of typical dynamics. Expand
The first law of general quantum resource theories
A set of laws for general quantum resource theories, which generalise the laws of thermodynamics are derived, which first test on thermodynamics with multiple conservation laws, and then apply to the theory of local operations under energetic restrictions. Expand
Quantum majorization and a complete set of entropic conditions for quantum thermodynamics
A quantum-mechanical generalization of majorization is used to derive a complete set of necessary and sufficient conditions for thermal transformations of quantum states, based on natural physical principles, namely, energy conservation, the existence of equilibrium states, and the requirement that quantum coherence be accounted for thermodynamics.

Reference frames, superselection rules, and quantum information
Recently, there has been much interest in a new kind of 'unspeakable' quantum information that stands to regular quantum information in the same way that a direction in space or a moment in timeExpand
Beyond heat baths II: framework for generalized thermodynamic resource theories
Thermodynamics, which describes vast systems, has been reconciled with small scales, relevant to single-molecule experiments, in resource theories. Resource theories have been used to model exchangesExpand
Beyond heat baths: Generalized resource theories for small-scale thermodynamics.
Thermodynamics has recently been extended to small scales with resource theories that model heat exchanges. Real physical systems exchange diverse quantities: heat, particles, angular momentum, etc.Expand
