Comment on "Thermodynamic Principle for Quantum Metrology"
Shane Dooley, Michael J. Kewming, Mark T. Mitchison +1
In Phys. Rev. Lett. 128, 200501 (2022) the authors consider the thermodynamic cost of quantum metrology. One of the main results is $\mathcal{S} \geq \log(2) \| h_λ\|^{-2} F_Q [ψ_λ…
Robust and Efficient High-dimensional Quantum State Tomography
Markus Rambach, Mahdi Qaryan, Michael Kewming +3
The exponential growth in Hilbert space with increasing size of a quantum system means that accurately characterising the system becomes significantly harder with system dimension…
A Physical Quantum Agent
Michael. J. Kewming, Sally Shrapnel, Gerard. J. Milburn
The concept of an embodied intelligent agent is a key concept in modern artificial intelligence and robotics. Physically, an agent is an open system embedded in an environment that…
Quantum Correlations in the Kerr Ising Model
Michael Kewming, Sally Shrapnel, Gerard Milburn
In this article we present a full description of the quantum Kerr Ising model---a linear optical network of parametrically pumped Kerr non-linearities. We consider the non-dissapat…
Hiding Ignorance Using High Dimensions
M. J. Kewming, S. Shrapnel, A. G. White +1
The absence of information -- entirely or partly -- is called ignorance. Naturally, one might ask if some ignorance of a whole system will imply some ignorance of its parts. Our cl…
Indefinite Causal Order in a Quantum Switch
K. Goswami, C. Giarmatzi, M. Kewming +4
In quantum mechanics events can happen in no definite causal order: in practice this can be verified by measuring a causal witness, in the same way that an entanglement witness ver…
