Deciding the Attainability of the Multiparameter Quantum Fisher Information is NP-Hard
Lorcan O. Conlon, Laura Shou, V Vijendran +7
The quantum Fisher information (QFI) sets a fundamental bound on the attainable precision when estimating multiple parameters simultaneously. Incompatibility among the individually…
OQMD: Single-Qubit Rotation Control Improves Low-CNOT Multiclass Quantum Classification
Michael A. Magid, Melissa Zeynep Ertem, Jun Suzuki
Near-term variational classifiers incur substantial error and latency from two-qubit gates, yet practitioners often assume that additional entangling depth is the default route to…
Saturating the Quantum Cramér--Rao Bound in Prioritised Parameter Estimation
Simon K. Yung, Aritra Das, Jun Suzuki +4
Measurement incompatibility is a cornerstone of quantum mechanics. In the context of estimating multiple parameters of a quantum system, this manifests as a fundamental trade-off b…
Holevo Cramér-Rao bound: How close can we get without entangling measurements?
Aritra Das, Lorcán O. Conlon, Jun Suzuki +3
In multi-parameter quantum metrology, the resource of entanglement can lead to an increase in efficiency of the estimation process. Entanglement can be used in the state preparatio…
Role of the extended Hilbert space in the attainability of the Quantum Cramér-Rao bound for multiparameter estimation
Lorcan O. Conlon, Jun Suzuki, Ping Koy Lam +1
The symmetric logarithmic derivative Cramér-Rao bound (SLDCRB) provides a fundamental limit to the minimum variance with which a set of unknown parameters can be estimated in an un…
