Maximal complementarity in the n-qubit Pauli group
Markus Frembs, Giovanni Natale, Christopher S. P. Wever +1
Observables in quantum mechanics are generally complementary, that is, they reveal mutually incompatible pieces of information about a given system. This property is not only a fun…
An algebraically closed family of informational n-qubit purity invariants
Markus Frembs, Giovanni Natale, Christopher S. P. Wever +1
We present a family of quadratics in Pauli expectation values, and prove that they constitute state-independent invariants for all n-qubit pure states. This family generalises the…
Gauss law codes and vacuum codes from lattice gauge theories
Javier P. Lacambra, Aidan Chatwin-Davies, Masazumi Honda +1
We develop a comprehensive framework for constructing quantum error correcting codes (QECCs) from Abelian lattice gauge theories (LGTs) using quantum reference frames (QRFs) as a u…
On the relation between perspective-neutral, algebraic, and effective quantum reference frames
Julian De Vuyst, Philipp A. Hoehn, Artur Tsobanjan
The framework of internal quantum reference frames (QRFs) constitutes a universal toolset for dealing with symmetries in quantum theory and has led to new revelations in quantum gr…
A correspondence between quantum error correcting codes and quantum reference frames
Sylvain Carrozza, Aidan Chatwin-Davies, Philipp A. Hoehn +1
In a gauge theory, a collection of kinematical degrees of freedom is used to redundantly describe a smaller amount of gauge-invariant information. In a quantum error correcting cod…
Quantum Frame Relativity of Subsystems, Correlations and Thermodynamics
Philipp A. Hoehn, Isha Kotecha, Fabio M. Mele
It was recently noted that different internal quantum reference frames (QRFs) partition a system in different ways into subsystems, much like different inertial observers in specia…
Matter relative to quantum hypersurfaces
Philipp A. Hoehn, Andrea Russo, Alexander R. H. Smith
We explore the canonical description of a scalar field as a parameterized field theory on an extended phase space that includes additional embedding fields that characterize spacet…
