In a new study from Skoltech and the University of Kentucky, researchers have found a new connection between quantum information and quantum field theory. This work attests to the growing role of quantum information theory […]
A team at the Technical University of Munich (TUM) has designed and commissioned the production of a computer chip that implements post-quantum cryptography very efficiently. Such chips could provide protection against future hacker attacks using […]
Physicists have created a new way to observe details about the structure and composition of materials that improves upon previous methods. Conventional spectroscopy changes the frequency of light shining on a sample over time to […]
An understanding of numbers is often viewed as a distinctly human faculty — a hallmark of our intelligence that, along with language, sets us apart from all other animals. But that couldn’t be further from […]

An artificially created spin defect (qubit) in a crystal lattice of boron nitride is suitable as a sensor enabling the measurement of different changes in its local environment. The qubit is a boron vacancy located […]
PRESS RELEASE: Qu&Co announces new investment round to accelerate and expand the development of its quantum application platforms for chemistry, multiphysics and finance. The companies involved in the funding round did not release information on […]
Quantum 5, 522 (2021). https://doi.org/10.22331/q-2021-08-09-522 Although quantum channels underlie the dynamics of quantum states, maps which are not physical channels — that is, not completely positive — can often be encountered in settings such as […]
Quantum 5, 521 (2021). https://doi.org/10.22331/q-2021-08-09-521 Covariant codes are quantum codes such that a symmetry transformation on the logical system could be realized by a symmetry transformation on the physical system, usually with limited capability of […]
Quantum 5, 520 (2021). https://doi.org/10.22331/q-2021-08-09-520 The operational formulations of quantum theory are drastically time oriented. However, to the best of our knowledge, microscopic physics is time-symmetric. We address this tension by showing that the asymmetry […]
