Maximally coherent mixed states: Complementarity between maximal coherence and mixedness
Uttam Singh, Manabendra Nath Bera, Himadri Shekhar Dhar +1
Quantum coherence is a key element in topical research on quantum resource theories and a primary facilitator for design and implementation of quantum technologies. However, the re…
Measuring Quantum Coherence with Entanglement
Alexander Streltsov, Uttam Singh, Himadri Shekhar Dhar +2
Quantum coherence is an essential ingredient in quantum information processing and plays a central role in emergent fields such as nanoscale thermodynamics and quantum biology. How…
Limit on Time-Energy Uncertainty with Multipartite Entanglement
Manabendra Nath Bera, R. Prabhu, Arun Kumar Pati +2
We establish a relation between the geometric time-energy uncertainty and multipartite entanglement. In particular, we show that the time-energy uncertainty relation is bounded bel…
Multisite Entanglement acts as a Better Indicator of Quantum Phase Transitions in Spin Models with Three-spin Interactions
Manabendra N. Bera, R. Prabhu, Aditi Sen De +1
We employ a genuine multipartite entanglement measure, the generalized geometric measure, for investigating the quantum phase transition in an infinite quantum spin-1/2 chain with…
