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…
Performance of rotation-symmetric bosonic codes in the presence of random telegraph noise
Adithi Udupa, Timo Hillmann, Rabsan Galib Ahmed +2
Decoherence in quantum devices, such as qubits and resonators, is often caused by bistable fluctuators modeled as random telegraph noise (RTN), leading to significant dephasing. We…
