Physicists are re-examining the foundations of quantum physics from the perspective of momentum and exploring what happens when the momentum of light is reduced to zero. Click to rate this post! [Total: 0 Average: 0]You […]
At the atomic and subatomic scales, objects behave in ways that challenge the classical worldview based on day-to-day interactions with macroscopic reality. A familiar example is the discovery that electrons can behave as both particles […]

Quantum 6, 702 (2022). https://doi.org/10.22331/q-2022-04-27-702 Topological phases are characterized by their entanglement properties, which is manifest in a direct relation between entanglement spectra and edge states discovered by Li and Haldane. We propose to leverage […]
Quantum 6, 701 (2022). https://doi.org/10.22331/q-2022-04-27-701 The average entanglement entropy (EE) of the energy eigenstates in non-vanishing partitions has been recently proposed as a diagnostic of integrability in quantum many-body systems. For it to be a […]
Quantum 6, 700 (2022). https://doi.org/10.22331/q-2022-04-27-700 We carefully examine critical metrology and present an improved critical quantum metrology protocol which relies on quenching a system exhibiting a superradiant quantum phase transition beyond its critical point. We […]
