Approaching quantum-limited metrology with imperfect detectors by using weak-value amplification
Liang Xu, Zexuan Liu, Animesh Datta +4
Weak value amplification (WVA) is a metrological protocol that amplifies ultra-small physical effects. However, the amplified outcomes necessarily occur with highly suppressed prob…
Towards a Spectroscopic Protocol for Unambiguous Detection of Quantum Coherence in Excitonic Energy Transport
Max Marcus, George Knee, Animesh Datta
The role of quantum effects in excitonic energy transport (EET) has been scrutinised intensely and with increasingly sophisticated experimental techniques. This increased complexit…
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…
Coarse-graining in retrodictive quantum state tomography
Dale Scerri, Erik M. Gauger, George C. Knee
Quantum state tomography often operates in the highly idealised scenario of assuming perfect measurements. The errors implied by such an approach are entwined with other imperfecti…
Seeing opportunity in every difficulty: protecting information with weak value techniques
George C. Knee, G. Andrew D. Briggs
A weak value is an effective description of the influence of a pre and post-selected 'principal' system on another 'meter' system to which it is weakly coupled. Weak values can des…
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…
