Quantum 8, 1224 (2024). https://doi.org/10.22331/q-2024-01-10-1224 We introduce a framework to compute upper bounds for temporal correlations achievable in open quantum system dynamics, obtained by repeated measurements on the system. As these correlations arise by virtue […]
All the magnets you have ever interacted with, such as the tchotchkes stuck to your refrigerator door, are magnetic for the same reason. But what if there were another, stranger way to make a material […]
Quantum 8, 1223 (2024). https://doi.org/10.22331/q-2024-01-10-1223 Quantum mechanics does not provide any ready recipe for defining energy density in space, since the energy and coordinate do not commute. To find a well-motivated energy density, we start […]

Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment proposed by theoretical physicists in a recent paper published in Physical Review Letters. An object evolving in […]
Quantum 8, 1222 (2024). https://doi.org/10.22331/q-2024-01-10-1222 In this paper we aim to push the analogy between thermodynamics and quantum resource theories one step further. Previous inspirations were based predominantly on thermodynamic considerations concerning scenarios with a […]
Quantum 8, 1221 (2024). https://doi.org/10.22331/q-2024-01-10-1221 Ground states of local Hamiltonians are of key interest in many-body physics and also in quantum information processing. Efficient verification of these states are crucial to many applications, but very […]
Quantum 8, 1220 (2024). https://doi.org/10.22331/q-2024-01-10-1220 There is a folkloric belief that a depth-$Theta(m)$ quantum circuit is needed to estimate the trace of the product of $m$ density matrices (i.e., a multivariate trace), a subroutine crucial […]
