Where do entangled multiple-qubit systems store information? For information
injected into a qubit, this question is nontrivial and interesting since the
entanglement delocalizes the information. So far, a common picture is that of a
qubit and its...

Quantum fields in vacuum states carry an infinite amount of quantum
entanglement, and its entanglement entropy has the ultraviolet divergence.
Harvesting protocols of the vacuum entanglement had been investigated, but its
efficiency is very low to...

In quantum field theory particles are physically defined as what Unruh-DeWitt
particle detectors observe. By detecting a particle mode Tex, a reduced density
operator for a quantum state of Tex is constructed. Even if the entire quantum
state of t...

Quantum energy teleportation (QET) is a proposed protocol related to the
quantum vacuum. The edge channels in a quantum Hall system is well suited for
the experimental verification of QET. For this purpose, we examine a charge
density wave excited...

We propose a model with multiple qubits that reproduces the thermal
properties of 4-dimensional (4-dim) Schwarzschild black holes (BHs) by
simultaneously taking account of the emission of Hawking particles and the
zero-energy soft hair evaporation...
