Parity-sensitive inhomogeneous dephasing of macroscopic spin ensembles
Parity-sensitive inhomogeneous dephasing of macroscopic spin ensembles
Spin ensembles play a pivotal role in various quantum applications such as metrology and simulating many-body physics. Recent research has proposed utilizing spin cat states to encode logical quantum information, with potentially logical lifetimes on the order of seconds via enhanced collective interactions that scale with system size. We investigate …
