Description
Quantum information has shaped physics and science in the past
decades.
On the one hand, quantum information studies the theoretical aspects
of information theory when quantum systems are employed.
On the other, quantum information promises technological revolutions
far beyond our current capabilities. These include quantum
computers, quantum communications and quantum cryptography.
Regardless of the approach considered, quantum information is well
described and characterized by quantum mechanics. Experiments
have been so far successfully explained by quantum physics alone.
However, they are now reaching regimes where relativity cannot be
ignored. A completely novel approach needs to be taken in order to
give correct predictions at the overlap of relativity and quantum
science; these will provide us with better ways to characterize our
future technologies, our theory and, ultimately, our ability to test the
fundamental laws of nature.
We present recent advances in the field of relativistic quantum
information. We focus our attention on theoretical aspects and
predictions of possible experiments that can test the role of
paradigmatic quantum information resources, such as entanglement,
in phenomena that occur at the overlap of relativity and quantum
physics. In particular we focus on a recently proposed gravitational
wave antenna based on micrometer-size Bose Einstein Condensates.
We then discuss the role of the information theoretical aspects of the
proposal, such as optimisation of, and ultimate bounds on,
measurements, which are paramount for the success of the
technology.
We conclude with an overlook on future directions and applications.
