Dissipative superradiant spin amplifier for enhanced quantum sensing
Martin Koppenhöfer, Peter Groszkowski, Hoi-Kwan Lau +1
Quantum metrology protocols exploiting ensembles of two-level systems and Ramsey-style measurements are ubiquitous. However, in many cases excess readout noise severely degrade…

Reservoir-engineered spin squeezing: macroscopic even-odd effects and hybrid-systems implementations
Peter Groszkowski, Martin Koppenhöfer, Hoi-Kwan Lau +1
We revisit the dissipative approach to producing and stabilizing spin-squeezed states of an ensemble of two-level systems, providing a detailed analysis of two surprising yet g…
