Dicke superposition probes for noise-resilient Heisenberg and super-Heisenberg Metrology
Sudha, B. N. Karthik, K. S. Akhilesh +1
Phase sensing with entangled multi-qubit states in the presence of noise is a central theme of modern quantum metrology. The present work investigates Dicke state superposition pro…
Canonical forms of two-qubit states under local operations
Sudha, H. S. Karthik, Rajarshi Pal +4
Canonical forms of two-qubits under the action of stochastic local operations and classical communications (SLOCC) offer great insight for understanding non-locality and entangleme…
Geometric phases for finite-dimensional systems -- the roles of Bargmann Invariants, Null Phase Curves and the Schwinger Majorana SU(2) framework
K S Akhilesh, Arvind, S Chaturvedi +2
We present a study of the properties of Bargmann Invariants (BI) and Null Phase Curves (NPC) in the theory of the geometric phase for finite dimensional systems. A recent suggestio…
Monogamous nature of symmetric multiqubt states with distinct spinors
Sudha, K. S. Akhilesh, B. G. Divyamani +2
Monogamy relations place restrictions on the shareability of quantum corellations in multipartite states. Being an intrinsic quantum feature, monogamy property throws light on {\em…
Spin squeezing in Dicke-class of states with non-orthogonal spinors
K. S. Akhilesh, K. S. Mallesh, Sudha +1
The celebrated Majorana representation is exploited to investigate spin squeezing in different classes of pure symmetric states of N qubits with two distinct spinors, namely the Di…
Spin squeezing in symmetric multiqubit states with two distinct Majorana spinors
K. S. Akhilesh, B. G. Divyamani, Shenoy Sudha +2
Majorana geometric representation of pure N-qubit states obeying exchange symmetry is em- ployed to explore spin squeezing properties in the family of states with two distinct spin…
