Limits for molecular spectroscopy from quantum channel discrimination
Anirban Dey, Akib Karim, Pieter Kok +2
Absorption spectroscopy identifies molecules by detecting frequency-dependent optical loss, and its fundamental limit is a quantum channel-discrimination problem. In this work, we…
Error bounds for the Floquet-Magnus expansion and their application to the semiclassical quantum Rabi model
Anirban Dey, Davide Lonigro, Kazuya Yuasa +1
We present a general, nonperturbative method for deriving effective Hamiltonians of arbitrary order for periodically driven systems, based on an iterated integration by parts techn…
Qualitative differences in the robust controllability of model two-qubit systems
Anirban Dey, Mattias T. Johnsson, Daniel Burgarth
The precise implementation and manipulation of quantum gates is key to extracting advantages from future quantum technologies. Achieving this requires very accurate control over th…
Quantum-Optimal Frequency Estimation of Stochastic AC Fields
Anirban Dey, Sara Mouradian, Cosmo Lupo +1
Resolving frequencies in a time-dependent field is classically limited by the measurement bandwidth. Using tools from quantum metrology and quantum control may overcome this limit,…
Creation and manipulation of surface code defects with quantum optimal control
Omar Raii, Anirban Dey, Florian Mintert +1
The surface code is a spin-1/2 lattice system that can exhibit non-trivial topological order when defects are punctured in the lattice and thus can be used as a stabiliser code. Th…
