Low-depth measurement-based deterministic quantum state preparation
Roselyn Nmaju, Fiona Speirits, Sarah Croke
We present a low-depth amplitude encoding method for arbitrary quantum state preparation. Building on the foundation of an existing divide-and-conquer algorithm, we propose a metho…
Dressing the Lorentz atom
Stephen M. Barnett, James D. Cresser, Sarah Croke
We investigate the effects of the electromagnetic vacuum field on a harmonically bound electron. We show that in the electric-dipole approximation the model atom couples only to an…
Revisiting the damped quantum harmonic oscillator
Stephen M. Barnett, James D. Cresser, Sarah Croke
We reanalyse the quantum damped harmonic oscillator, introducing three less than common features. These are (i) the use of a continuum model of the reservoir rather than an ensembl…
Quantum state preparation of gravitational waves
Fergus Hayes, Sarah Croke, Chris Messenger +1
We detail a quantum circuit capable of efficiently encoding analytical approximations to gravitational wave signal waveforms of compact binary coalescences into the amplitudes of q…
Multi-partite subspaces containing no locally inaccessible information
Sarah Croke
One notion of non-locality in quantum theory is the fact that information may be encoded in a composite system in such a way that it is not accessible through local measurements, e…
Measurement disturbance tradeoffs in three-qubit unsupervised quantum classification
Hector Spencer-Wood, Sarah Croke, John Jeffers
We consider measurement disturbance tradeoffs in quantum machine learning protocols which seek to learn about quantum data. We study the simplest example of a binary classification…
