Quantum 7, 989 (2023). https://doi.org/10.22331/q-2023-04-27-989 In the training of over-parameterized model functions via gradient descent, sometimes the parameters do not change significantly and remain close to their initial values. This phenomenon is called $textit{lazy training}$ […]
Quantum 7, 988 (2023). https://doi.org/10.22331/q-2023-04-27-988 Linear regression is a widely used technique to fit linear models and finds widespread applications across different areas such as machine learning and statistics. In most real-world scenarios, however, linear […]
Quantum 7, 987 (2023). https://doi.org/10.22331/q-2023-04-27-987 Topological quantum phases of quantum materials are defined through their topological invariants. These topological invariants are quantities that characterize the global geometrical properties of the quantum wave functions and thus […]

Insider Brief: QantX has awarded Light Trace Photonics a £50,000 Blavatnik Prize for Innovation to support the development of their device for training the next generation of photonic engineers. Light Trace Photonics is a startup […]
Insider Brief A team 0f University of Innsbruck researchers demonstrated a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations. The researchers fully entangled two qudits, or quantum digits, each […]
By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists have shown that this is the case. The findings […]
Experts in nuclear physics and quantum information have demonstrated the application of a photon-number-resolving system to accurately resolve more than 100 photons. The feat is a major step forward in capability for quantum computing development […]
Intel has been one of the key pioneers of silicon transistors for classical computers for the last fifty or so years. Now, it is one with a solid quantum computing strategy. Key Concepts Behind Intel’s […]
The glowing dots in these images are single rubidium atoms, pristinely arranged in arrays about as wide as a human hair. The team of CQT Principal Investigator Loh Huanqian captured these pictures to show how […]
