The Quantum Internet: A Hardware Review
In the century following its discovery, applications for quantum physics are
opening a new world of technological possibilities. With the current decade
witnessing quantum supremacy, quantum technologies are already starting to
change the ways information is generated, transmitted, stored and processed.
The next major milestone in quantum technology is already rapidly emerging --
the quantum internet. Since light is the most logical candidate for quantum
communication, quantum photonics is a critical enabling technology. This paper
reviews the hardware aspects of the quantum internet, mainly from a photonics
perspective. Though a plethora of quantum technologies and devices have emerged
in recent years, we are more focused on devices or components that may enable
the quantum internet. Our approach is primarily qualitative, providing a broad
overview of the necessary technologies for a large-scale quantum internet.Comment: 38 pages, 1 tabl
Integrated Photonic Platforms for Quantum Technology: A Review
Quantum information processing has conceptually changed the way we process
and transmit information. Quantum physics, which explains the strange behaviour
of matter at the microscopic dimensions, has matured into a quantum technology
that can harness this strange behaviour for technological applications with
far-reaching consequences, which uses quantum bits (qubits) for information
processing. Experiments suggest that photons are the most successful candidates
for realising qubits, which indicates that integrated photonic platforms will
play a crucial role in realising quantum technology. This paper surveys the
various photonic platforms based on different materials for quantum information
processing. The future of this technology depends on the successful materials
that can be used to universally realise quantum devices, similar to silicon,
which shaped the industry towards the end of the last century. Though a
prediction is implausible at this point, we provide an overview of the current
status of research on the platforms based on various materials.Comment: 48 pages, 3 figure
