Opinion formation models with extreme switches and disorder: critical behaviour and dynamics
Kathakali Biswas, Parongama Sen
In a three state kinetic exchange opinion formation model, the effect of extreme switches was considered in a recent paper. In the present work, we study the same model with disord…
Robust Quantum Arithmetic Operations with Intermediate Qutrits in the NISQ-era
Amit Saha, Anupam Chattopadhyay, Amlan Chakrabarti
Numerous scientific developments in this NISQ-era (Noisy Intermediate Scale Quantum) have raised the importance for quantum algorithms relative to their conventional counterparts d…
Entangled state distillation from single copy mixed states beyond LOCC
Indranil Biswas, Atanu Bhunia, Indrani Chattopadhyay +1
No pure entangled state can be distilled from a or mixed state by separable operations. In , pure entanglement can be distilled by separable o…
Discrete symmetry transformations on non-abelian gauge fields
Amitabha Lahiri, Palash B. Pal, Marina Shokova
All gauge bosons of a non-abelian gauge theory do not transform the same way under the discrete transformations of time-reversal and charge-conjugation. Moreover, the transformatio…
Exploring Earth's Ionosphere and its effect on low radio frequency observation with the uGMRT and the SKA
Sarvesh Mangla, Sumanjit Chakraborty, Abhirup Datta +1
The Earth's ionosphere introduces systematic effects that limit the performance of a radio interferometer at low frequencies (\,GHz). These effects become more pronounc…
Robust Quantum Circuit for Clique Problem with Intermediate Qudits
Arpita Sanyal, Amit Saha, Banani Saha +1
Clique problem has a wide range of applications due to its pattern matching ability. There are various formulation of clique problem like -clique problem, maximum clique problem…
