Optimising multipartite entanglement manipulation in quantum networks
Shashank Shekhar, David Elkouss, Siddhartha Santra
Long-range, genuine multipartite entanglement (GME) between distant parties in a quantum network is a crucial resource for distributed quantum information processing. Through contr…
Minimal Subsystems for Characterizing Genuine Multipartite Entanglement
Shashank Shekhar, Siddhartha Santra
Genuine multipartite entanglement (GME) is a valuable resource for quantum technologies, but quantifying it in many-body systems can be demanding since measures defined through opt…
Optimal resource requirements for connected quantum sub-networks
Shashank Shekhar, Md Sohel Mondal, Siddhartha Santra
The realization of a global quantum network capable of supporting secure communication and other quantum information processing (QIP) tasks hinges on the ability to distribute high…
Coined Quantum Walk on a Quantum Network
Jigyen Bhavsar, Shashank Shekhar, Siddhartha Santra
We explore a discrete-time, coined quantum walk on a quantum network where the coherent superposition of walker-moves originates from the unitary interaction of the walker-coin wit…
