Heisenberg-limited continuous-variable distributed quantum metrology with arbitrary weights
Wenchao Ge, Kurt Jacobs
Distributed quantum metrology (DQM) enables the estimation of global functions of d distributed parameters beyond the capability of separable sensors. Continuous-variable DQM invol…

Power-optimized amplitude modulation for robust trapped-ion entangling gates: a study of gate-timing errors
Luke Ellert-Beck, Wenchao Ge
Trapped-ion systems are a promising route toward the realization of both near-term and universal quantum computers. However, one of the pressing challenges is improving the fidelit…

Quantifying nonclassicality of mixed Fock states
Spencer Rogers, Tommy Muth, Wenchao Ge
Nonclassical states of bosonic modes are important resources for quantum-enhanced technologies. Yet, quantifying nonclassicality of these states, in particular mixed states, can be…
