Two-level systems represent the simplest nontrivial quantum objects, characterised by a pair of discrete energy eigenstates. Their dynamics under external driving fields underpin a wide spectrum of ...

Scientists have successfully achieved a quantum collective behavior of macroscopic mechanical oscillators, unlocking new possibilities in quantum technology. Quantum technologies are radically ...

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings show that a quantum process can appear memoryless from one perspective while ...

EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for ...

Recent research reveals that quantum mechanics can supersede the second law of thermodynamics at the atomic scale, challenging long-held principles of entropy and energy dissipation in microscopic ...

Schematic of a single photon with zero angular momentum (green) splitting into two photons (red) with either zero or opposite angular momenta (sketched through the spatially varying color), which adds ...

The quantum tangent kernel method is a mathematical approach used to understand how fast and how well quantum neural networks can learn. A quantum neural network is a machine learning model that runs ...
