A depolarizing choir sings in Gaussian harmony
Rabsan Galib Ahmed, Sujeet Bhalerao, Sungjai Lee +4
We study the noise threshold for positive quantum capacity for the qubit depolarizing channel. We explore analytically the action of the qubit depolarizing channel on the symmetric…
No cardinality bound for squashed entanglement
Rabsan Galib Ahmed, Graeme Smith
Squashed entanglement is an additive bipartite entanglement measure. For a state , it is defined as the infimum of all conditional mutual information evaluat…
Distributed Monogamy of Entanglement limits Quantum Channel Simulation
Rabsan Galib Ahmed, Graeme Smith
Entanglement is monogamous: if it is shared among more than two parties, the entanglement between any pair cannot be very strong. For an integer , -extendibility of a s…
No-Go Theorem for Gaussian Quantum Repeaters from Fractional Extendibility
Rabsan Galib Ahmed, Graeme Smith
Photon loss in optical channels fundamentally limits long-range reliable quantum communication. A standard approach to overcoming this limitation is the use of quantum repeater nod…
Single-letter one-way distillable entanglement for non-degradable states
Rabsan Galib Ahmed, Graeme Smith, Peixue Wu
The one-way distillable entanglement is a central operational measure of bipartite entanglement, quantifying the optimal rate at which maximally entangled pairs can be extracted by…
