Energetics of correlations in interacting systems
Nicolai Friis, Marcus Huber, Martí Perarnau-Llobet
A fundamental connection between thermodynamics and information theory arises from the fact that correlations exhibit an inherent work value. For noninteracting systems this transl…
Coherent controlization using superconducting qubits
Nicolai Friis, Alexey A. Melnikov, Gerhard Kirchmair +1
Coherent controlization, i.e., coherent conditioning of arbitrary single- or multi-qubit operations on the state of one or more control qubits, is an important ingredient for the f…
Heisenberg scaling in Gaussian quantum metrology
Nicolai Friis, Michalis Skotiniotis, Ivette Fuentes +1
We address the issue of precisely estimating small parameters encoded in a general linear transformation of the modes of a bosonic quantum field. Such Bogoliubov transformations fr…
Reasonable fermionic quantum information theories require relativity
Nicolai Friis
We show that any quantum information theory based on anticommuting operators must be supplemented by a superselection rule deeply rooted in relativity to establish a reasonable not…
