Entanglement Entropy and Quantum Field Theory: a Non-technical Introduction
There has been considerable interest in formulating measures of entanglement and applying them to extended quantum systems with many degrees of freedom, such as quantum spin chains, especially close to a quantum phase transition (see, e.g., several other reports in these proceedings). One of these measures is entanglement entropy. Suppose the whole system is in a pure quantum state |Ψ〉, with de...
متن کاملVoltage-Controlled Entanglement between Quantum- Dot Molecule and its Spontaneous Emission Fields via Quantum Entropy
The time evolution of the quantum entropy in a coherently driven threelevel quantum dot (QD) molecule is investigated. The entanglement of quantum dot molecule and its spontaneous emission field is coherently controlled by the gat voltage and the intensity of applied field. It is shown that the degree of entanglement between a three-level quantum dot molecule and its spontaneous emission fields...
متن کاملQuantum Entanglement and Entropy
Entanglement is the fundamental quantum property behind the now popular field of quantum transport of information. This quantum property is incompatible with the separation of a single system into two uncorrelated subsystems. Consequently, it does not require the use of an additive form of entropy. We discuss the problem of the choice of the most convenient entropy indicator, focusing our atten...
متن کاملEntanglement negativity in quantum field theory.
We develop a systematic method to extract the negativity in the ground state of a 1+1 dimensional relativistic quantum field theory, using a path integral formalism to construct the partial transpose ρ(A)(T(2) of the reduced density matrix of a subsystem [formula: see text], and introducing a replica approach to obtain its trace norm which gives the logarithmic negativity E=ln//ρ(A)(T(2))//. Th...
متن کاملEntropy bound and local quantum field theory
I comment on Ulvi Yurtsever’s result, which states that the entropy of a truncated bosonic Fock space is given by a holographic bound when the energy of the Fock states is constrained gravitationally. The derivation given in Yurtsever’s paper contains an subtle mistake, which invalidates the result. A more restrictive, non-holographic entropy bound is derived. PACS numbers: 04.70.-s, 03.67.-a
