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 […]
Quantum 5, 519 (2021). https://doi.org/10.22331/q-2021-08-09-519 We analyze bipartite matrices and linear maps between matrix algebras, which are respectively, invariant and covariant, under the diagonal unitary and orthogonal groups’ actions. By presenting an expansive list of […]
Quantum China is a weekly periodical focusing on China’s quantum information technology, providing a voice for the Chinese quantum technology. It focuses on eight major directions: Policy, Capital, Business, Technology, Research, Education, Conference, and People. […]
