Quantum communication facilitates the secure transmission of information and the distribution of entanglement, but the rates at which these tasks can be achieved are fundamentally constrained by the capacities of quantum channels. Although quantum re

Neural networks readily learn a subset of the modular arithmetic tasks, while failing to generalize on the rest. This limitation remains unmoved by the choice of architecture and training strategies. On the other hand, an analytical solution for the

Learning to grok: Emergence of in-context learning and skill composition in modular arithmetic tasks
Large language models can solve tasks that were not present in the training set. This capability is believed to be due to in-context learning and skill composition. In this work, we study the emergence of in-context learning and skill composition in

In multi-parameter quantum metrology, the resource of entanglement can lead to an increase in efficiency of the estimation process. Entanglement can be used in the state preparation stage, or the measurement stage, or both, to harness this advantage;

We have estimated the rate of production of lepton pairs from a magnetised hot and dense QCD medium. We get rid of all kinds of previously considered approximations in terms of the strength of the magnetic field as well as the components of the momen

Robust generalization is a major challenge in deep learning, particularly when the number of trainable parameters is very large. In general, it is very difficult to know if the network has memorized a particular set of examples or understood the unde

In this paper, a theoretical calculation of thermal di-lepton production rate (DPR) is reported from a hot and dense, unbounded rotating quark gluon plasma in the presence of very strong uniform background magnetic field typically generated at heavy-

The maximum amount of entanglement achievable under passive transformations by continuous-variable states is called the entanglement potential. Recent work has demonstrated that the entanglement potential is upper-bounded by a simple function of the

The quantum approximate optimisation algorithm (QAOA) is a hybrid quantum-classical algorithm used to approximately solve combinatorial optimisation problems. It involves multiple iterations of a parameterised ansatz comprising a problem and mixer Ha

We study the neutral pion mass in the presence of an external arbitrary magnetic field in the framework of the linear sigma model coupled to quark (LSMq) at finite temperature. In doing so, we have calculated the pion self-energy, constructed the dis
