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…
Multimode rotationally symmetric bosonic codes from group-theoretic construction
Rabsan Galib Ahmed, Adithi Udupa, Giulia Ferrini
We introduce a new family of multi-mode, rotationally symmetric bosonic codes inspired by the group-theoretic framework of [Phys. Rev. Lett. 133, 240603 (2024)]. Such a constructio…
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…
A violation of the Tsirelson bound in the pre-quantum theory of trace dynamics
Rabsan G. Ahmed, Tejinder P. Singh
The term Bell's theorem refers to a set of closely related results which imply that quantum mechanics is incompatible with local hidden variable theories. Bell's inequality is the…
