Magic transfer in quantum spin chains
Antonio Palamara, Chad Nelmes, Enrico C. Domanti +1
Quantum communication protocols based on spin chains have been extensively studied, yet their ability to transmit nonstabilizer resources has not been systematically addressed. We…
Approaching the Limit of Quantum Clock Precision
Chad Nelmes, Emanuel Schwarzhans, Tony Apollaro +2
Precise and autonomous clocks are of fundamental interest and central importance to both foundational studies and practical applications. Here, we construct a blueprint for a quant…
Fast and efficient long-distance quantum state transfer in long-range spin- models
F. Faria, C. C. Nelmes, T. J. G. Apollaro +2
Quantum state transfer is investigated beyond the nearest-neighbour coupling scheme in long spin- linear chains. Exploiting the properties of the next-nearest neighbou…
State transfer analysis for linear spin chains with non-uniform on-site energies
Chad C. Nelmes, Irene D'Amico, Timothy P. Spiller
High fidelity state transfer is an important ingredient of distributed quantum information processing. We present and analyse results on perfect and quasi-perfect state transfer wi…
Quasi-Perfect State Transfer in Spin Chains via Parametrization of On-Site Energies
Fateh Bezaz, Chad C. Nelmes, Marta P. Estarellas +2
In recent years, significant progress has been made in the field of state transfer in spin chains, with the aim of achieving perfect state transfer for quantum information processi…
