# Relativistic limits on quantum operations

@inproceedings{Lugt2021RelativisticLO, title={Relativistic limits on quantum operations}, author={Tein van der Lugt}, year={2021} }

. In this essay, we explore the limits imposed by the impossibility of superluminal signalling on the class of physically realisable quantum operations, focusing on the diﬀerence in approaches one can take towards this problem in Hilbert space quantum theory and algebraic quantum ﬁeld theory (AQFT). We review a recent proposal by Fewster and Verch for a generally covariant measurement scheme in AQFT, which we call the FV scheme; along the way, we argue that the framework as set up in its…

Impossible Measurements on Quantum Fields

- Physics
- 1956

It is shown that the attempt to extend the notion of ideal measurement to quantum field theory leads to a conflict with locality, because (for most observables) the state vector reduction associated…

A Generally Covariant Measurement Scheme for Quantum Field Theory in Curved Spacetimes

- PhysicsProgress and Visions in Quantum Theory in View of Gravity
- 2020

We propose and develop a measurement scheme for quantum field theory (QFT) in curved spacetimes, in which the QFT of interest, the “system”, is dynamically coupled to another, the “probe”, in a…

Quantum information processing and relativistic quantum fields

- Physics
- 2014

It is shown that an ideal measurement of a one-particle wave packet state of a relativistic quantum field in Minkowski spacetime enables superluminal signalling. The result holds for a measurement…

Measurement theory in local quantum physics

In this paper, we aim to establish foundations of measurement theory in local quantum physics. For this purpose, we discuss a representation theory of completely positive (CP) instruments on…

Algebraic Quantum Field Theory on Curved Spacetimes

In this chapter, we review all background material on algebraic quantum field theory on curved spacetimes which is necessary for understanding the cosmological applications discussed in the next…

Bell’s theorem for temporal order

- Physics, PhilosophyNature Communications
- 2019

A thought experiment is considered where a massive body in a spatial superposition leads to entanglement of temporal orders between time-like events, resulting in a violation of a Bell-type inequality.

Realization of qudits in coupled potential wells

- Physics
- 2016

The theoretical grounds underlying the double-well qubit dynamics are revisited, then novel extensions of these principles are suggested to a triple-well qutrit with periodic boundary conditions, followed by a general d-well analysis of qudits.

Causal and localizable quantum operations

- Mathematics
- 2001

We examine constraints on quantum operations imposed by relativistic causality. A bipartite superoperator is said to be localizable if it can be implemented by two parties (Alice and Bob) who share…
