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…
