Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a “stable” pair known as a diquark. It seems, however, that […]
Quantum coherence is a key ingredient of many fundamental tests and applications in quantum technology, including quantum communication, imaging, computing, sensing and metrology. However, the transfer of quantum coherence in free-space has so far been […]
Quantum 5, 474 (2021). https://doi.org/10.22331/q-2021-06-10-474 At the dawn of Quantum Physics, Wigner and Weisskopf obtained a full analytical description (a $textit{photon portrait}$) of the emission of a single photon by a two-level system, using the […]
Quantum 5, 473 (2021). https://doi.org/10.22331/q-2021-06-10-473 Recently a new class of quantum algorithms that are based on the quantum computation of the connected moment expansion has been reported to find the ground and excited state energies. […]
Quantum 5, 472 (2021). https://doi.org/10.22331/q-2021-06-10-472 This work analyzes correlations arising from quantum systems subject to sequential projective measurements to certify that the system in question has a quantum dimension greater than some $d$. We refine […]
Over the past century, quantum field theory has proved to be the single most sweeping and successful physical theory ever invented. It is an umbrella term that encompasses many specific quantum field theories — the […]
KETS Quantum Security has raised a £3.1 million ($4.38 million US) round to bring to market hardware to protect data from a new generation of cyberattacks that will use quantum computers to break through all […]
In a new study, researchers demonstrate an automated, easy-to-operate quantum key distribution (QKD) system using the fiber network in the city of Padua, Italy. The field test represents an important step toward implementing this highly […]
To find out more about the motivation, benefits, and opportunities of this newly announced plan to merge the two organizations, we talked with Tony Uttley, president of Honeywell Quantum Solutions and gained a few insights […]
Qu&Co, a leading European quantum computational software developer, has signed a collaboration agreement with Airbus for research, development and testing of quantum computational methods for flight physics simulations relevant for the European aerospace and defence sector. […]
