Quantum Process Randomness
Sreetama Das, Asutosh Kumar, Aditi Sen De +1
We study the optimization of any quantum process by minimizing the "randomness" in the measurement result at the output of that quantum process. We conceptualize and propose a meas…
Quantum discord and its allies: a review
Anindita Bera, Tamoghna Das, Debasis Sadhukhan +3
We review concepts and methods associated with quantum discord and related topics. We also describe their possible connections with other aspects of quantum information and beyond,…
Benford's law gives better scale exponents in phase transitions of quantum XY models
Ameya Deepak Rane, Utkarsh Mishra, Anindya Biswas +2
Benford's law is an empirical law predicting the distribution of the first significant digits of numbers obtained from natural phenomena and mathematical tables. It has been found…
Reply to Comment on "Regional Versus Global Entanglement in Resonating-Valence-Bond States"
Dagomir Kaszlikowski, Aditi Sen De, Ujjwal Sen +1
In Phys. Rev. Lett. 99, 170502 (2007) (arXiv:quant-ph/0703227), we prove that resonating-valence-bond (RVB) states on arbitrary lattices possess genuine multiparty entanglement, an…
Frustration, Area Law, and Interference in Quantum Spin Models
Aditi Sen De, Ujjwal Sen, Jacek Dziarmaga +2
We study frustrated quantum systems from a quantum information perspective. Within this approach, we find that highly frustrated systems do not follow any general ''area law'' of b…
Quantum Correlation Without Classical Correlations
Dagomir Kaszlikowski, Aditi Sen De, Ujjwal Sen +2
We show that genuine multiparty quantum correlations can exist on its own, without a supporting background of genuine multiparty classical correlations, even in macroscopic systems…
