Proteins are the molecular machines that sustain every cell and organism, and knowing what they look like will be critical to untangling how they function normally and malfunction in disease. Now researchers have taken a […]
In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking work, […]
Quantum 8, 1341 (2024). https://doi.org/10.22331/q-2024-05-08-1341 We propose an analogue of $text{SU}(1,1)$ interferometry to measure rotation of a spin by using two-spin squeezed states. Attainability of the Heisenberg limit for the estimation of the rotation angle […]
A large international team of physicists working on the BES III collaboration has announced possible physical evidence of glueballs. In their study, published in the journal Physical Review Letters, the group analyzed decaying particles in […]
A team of researchers from the 5th Institute of Physics at the University of Stuttgart is making important progress in the field of quantum simulation and quantum computing based on Rydberg atoms by overcoming a […]
Insider Brief Researchers report they achieved the fractional quantum anomalous Hall state of photons for the first time. The team suggests this is a step they say will have implications for the development of fault […]
Insider Brief Innovate UK launched a new up to £3 million funding initiative to support collaborative research and innovation projects. The initiative is part of the UK Government’s International Science Partnerships Fund (ISPF), managed by […]
Quantum 8, 1340 (2024). https://doi.org/10.22331/q-2024-05-08-1340 The Haar measure plays a vital role in quantum information, but its study often requires a deep understanding of representation theory, posing a challenge for beginners. This tutorial aims to […]
Quantum 8, 1339 (2024). https://doi.org/10.22331/q-2024-05-08-1339 Absolutely maximally entangled (AME) states of $k$ qudits (also known as perfect tensors) are quantum states that have maximal entanglement for all possible bipartitions of the sites/parties. We consider the […]
Insider Brief PacketLight Networks successfully demonstrated quantum key distribution (QKD) over DWDM links with Toshiba Digital Solutions Corporation. The demonstration showcases the integration of the solutions can build efficient, secure, and scalable quantum-safe communication networks. […]
