Fidelity estimation of quantum states on a silicon photonic chip
Sabine Wollmann, Xiaogang Qiang, Sam Pallister +3
As a measure of the 'closeness' of two quantum states, fidelity plays a fundamental role in quantum information theory. Fidelity estimation protocols try to strike a balance betwee…
L00L entanglement and the twisted quantum eraser
Dylan Danese, Sabine Wollmann, Saroch Leedumrongwatthanakun +4
We demonstrate the generation of unbalanced two-photon entanglement in the Laguerre-Gaussian (LG) transverse-spatial degree-of-freedom, where one photon carries a fundamental (Gaus…
Correcting for finite statistics effects in a quantum steering experiment
Sophie Engineer, Ana C. S. Costa, Alexandre C. Orthey +7
Verifying entanglement between parties is essential for creating secure quantum communication. However, finite statistics can lead to false positive outcomes in any tests for entan…
Scheme for single-shot frequency comb absorption sensing on chip
Jake Biele, Sabine Wollmann, Euan Allen
Frequency comb absorption spectroscopy combined with low-noise, fast homodyne measurements provide a toolbox for ultra-sensitive absorption measurements. Integrating these schemes…
Maximising Precision in Saturation-Limited Absorption Measurements
J. Biele, S. Wollmann, J. W. Silverstone +2
Quantum fluctuations in the intensity of an optical probe is noise which limits measurement precision in absorption spectroscopy. Increased probe power can offer greater precision,…
Experimental demonstration of robust quantum steering
Sabine Wollmann, Roope Uola, Ana C. S. Costa
We analyse and experimentally demonstrate quantum steering using criteria based on generalised entropies and criteria with minimal assumptions based on the so-called dimension-boun…
Conclusive experimental demonstration of one-way Einstein-Podolsky-Rosen steering
Nora Tischler, Farzad Ghafari, Travis J. Baker +10
Einstein-Podolsky-Rosen steering is a quantum phenomenon wherein one party influences, or steers, the state of a distant party's particle beyond what could be achieved with a separ…
Strong unitary and overlap uncertainty relations: theory and experiment
Kok-Wei Bong, Nora Tischler, Raj B. Patel +3
We derive and experimentally investigate a strong uncertainty relation valid for any unitary operators, which implies the standard uncertainty relation as a special case, and w…
Necessary Condition for Steerability of Arbitrary Two-Qubit States with Loss
Travis J. Baker, Sabine Wollmann, Geoff J. Pryde +1
Einstein-Podolsky-Rosen steering refers to the quantum phenomenon whereby the state of a system held by one party can be "steered" into different states at the will of another, dis…
Heralded quantum steering over a high-loss channel
Morgan M. Weston, Sergei Slussarenko, Helen M. Chrzanowski +6
Entanglement is the key resource for many long-range quantum information tasks, including secure communication and fundamental tests of quantum physics. These tasks require robust…
Reference frame independent Einstein-Podolsky-Rosen steering
Sabine Wollmann, Michael J. W. Hall, Raj B. Patel +2
Protocols for testing or exploiting quantum correlations-such as entanglement, Bell nonlocality, and Einstein-Podolsky-Rosen steering- generally assume a common reference frame bet…
Efficient and pure femtosecond-pulse-length source of polarization-entangled photons
Morgan M. Weston, Helen M. Chrzanowski, Sabine Wollmann +9
We present a source of polarization entangled photon pairs based on spontaneous parametric downconversion engineered for frequency uncorrelated telecom photon generation. Our sourc…
Observation of genuine one-way Einstein-Podolsky-Rosen steering
Sabine Wollmann, Nathan Walk, Adam J. Bennet +2
Within the hierarchy of inseparable quantum correlations, Einstein-Podolsky-Rosen steering is distinguished from both entanglement and Bell nonlocality by its asymmetry -- there ex…
