Ground-State Cooling of Levitated Magnets in Low-Frequency Traps
Kirill Streltsov, Julen S. Pedernales, Martin B. Plenio
We present a ground-state cooling scheme for the mechanical degrees of freedom of mesoscopic magnetic particles levitated in low-frequency traps. Our method makes use of a binary s…
Enhanced force sensitivity and entanglement in periodically driven optomechanics
F. Cosco, J. S. Pedernales, M. B. Plenio
Squeezing is a resource that enables precision enhancements in quantum metrology and can be used as a basis for the generation of entanglement by linear optics. While strong squeez…
Decoherence-Free Rotational Degrees of Freedom for Quantum Applications
Julen S. Pedernales, Francesco Cosco, Martin B. Plenio
We employ spherical -designs for the systematic construction of solids whose rotational degrees of freedom can be made robust to decoherence due to external fluctuating fields w…
Motional Dynamical Decoupling for Matter-Wave Interferometry
Julen S. Pedernales, Gavin W. Morley, Martin B. Plenio
Matter-wave interferometry provides a remarkably sensitive tool for probing minute forces and, potentially, the foundations of quantum physics by making use of interference between…
