Covert sensing using floodlight illumination
Christos N. Gagatsos, Boulat A. Bash, Animesh Datta +2
We propose a scheme for covert active sensing using floodlight illumination from a THz-bandwidth amplified spontaneous emission (ASE) source and heterodyne detection. We evaluate t…
Accrediting outputs of noisy intermediate-scale quantum computing devices
Samuele Ferracin, Theodoros Kapourniotis, Animesh Datta
We present an accreditation protocol for the outputs of noisy intermediate-scale quantum devices. By testing entire circuits rather than individual gates, our accreditation protoco…
Quantum leakage detection using a model-independent dimension witness
Armands Strikis, Animesh Datta, George C. Knee
Users of quantum computers must be able to confirm they are indeed functioning as intended, even when the devices are remotely accessed. In particular, if the Hilbert space dimensi…
Subtleties of witnessing quantum coherence in non-isolated systems
George C. Knee, Max Marcus, Luke D. Smith +1
Identifying non-classicality unambiguously and inexpensively is a long-standing open challenge in physics. The No-Signalling-In-Time protocol was developed as an experimental test…
Fault-tolerant quantum metrology
Theodoros Kapourniotis, Animesh Datta
We introduce the notion of fault-tolerant quantum metrology to overcome noise beyond our control -- associated with sensing the parameter, by reducing the noise in operations under…
Fundamental quantum limits of multi-carrier optomechanical sensors
Dominic Branford, Haixing Miao, Animesh Datta
Optomechanical sensors involving multiple optical carriers can experience mechanically mediated interactions causing multi-mode correlations across the optical fields. One instance…
