Robust entanglement-based magnetic field sensor beyond the standard quantum limit
Tohru Tanaka, Paul Knott, Yuichiro Matsuzaki +4
Recently, there have been significant developments in entanglement-based quantum metrology. However, entanglement is fragile against experimental imperfections, and quantum sensing…
Generating non-classical states from spin coherent states via interaction with ancillary spins
Shane Dooley, Jaewoo Joo, Timothy Proctor +1
The generation of non-classical states of large quantum systems has attracted much interest from a foundational perspective, but also because of the significant potential of such s…
Fractional Revivals, Multiple-Cat States and Quantum Carpets in the Interaction of a Qubit with Qubits
Shane Dooley, Timothy P. Spiller
We study the dynamics of a system comprising a single qubit interacting equally with qubits (a "spin star" system). Although this model can be solved exactly, the exact solutio…
Quantum computation mediated by ancillary qudits and spin coherent states
Timothy J. Proctor, Shane Dooley, Viv Kendon
Models of universal quantum computation in which the required interactions between register (computational) qubits are mediated by some ancillary system are highly relevant to expe…
