Slowing quantum decoherence of oscillators by hybrid processing
Kimin Park, Jacob Hastrup, Jonas Schou Neergaard-Nielsen +3
Quantum information encoded into superposition of coherent states is an illustrative representative of practical applications of macroscopic quantum coherence possessing. However,…
Optimal Quantum Thermometry with Coarse-grained Measurements
Karen V. Hovhannisyan, Mathias R. Jørgensen, Gabriel T. Landi +3
Precise thermometry for quantum systems is important to the development of new technology, and understanding the ultimate limits to precision presents a fundamental challenge. It i…
Hybrid Thermal Machines: Generalized Thermodynamic Resources for Multitasking
Gonzalo Manzano, Rafael Sánchez, Ralph Silva +4
Thermal machines perform useful tasks--such as producing work, cooling, or heating--by exchanging energy, and possibly additional conserved quantities such as particles, with reser…
Tight bound on finite-resolution quantum thermometry at low temperatures
Mathias R. Jørgensen, Patrick P. Potts, Matteo G. A. Paris +1
Precise thermometry is of wide importance in science and technology in general and in quantum systems in particular. Here, we investigate fundamental precision limits for thermomet…
Measurement-free preparation of grid states
Jacob Hastrup, Kimin Park, Jonatan Bohr Brask +2
Quantum computing potentially offers exponential speed-ups over classical computing for certain tasks. A central, outstanding challenge to making quantum computing practical is to…
Informationally restricted quantum correlations
Armin Tavakoli, Emmanuel Zambrini Cruzeiro, Jonatan Bohr Brask +2
Quantum communication leads to strong correlations, that can outperform classical ones. Complementary to previous works in this area, we investigate correlations in prepare-and-mea…
