Quantum efficiency of the CIS115 in a radiation environment Open

Chiaki Crews, Matthew R. Soman, Edgar A. H. Allanwood, Konstantin D. Stefanov, M. R. Leese , et al. · 2020

An optical bench setup for quantum efficiency (QE) measurements across the 350 nm to 1100 nm range has been developed at the Open University’s Centre for Electronic Imaging (CEI). Here we use it to measure the performance of a monolithic s…

Approaching the quantum limit of precision in absorbance estimation using classical resources Open

Euan J. Allen, Javier Sabines-Chesterking, Alex McMillan, Siddarth Koduru Joshi, Peter S. Turner , et al. · 2020

The utility of transmission measurement has made it a target for quantum\nenhanced measurement strategies. Here we find if the length of an absorbing\nobject is a controllable variable, then via the Beer-Lambert law, classical\nstrategies …

CCDC 1942907: Experimental Crystal Structure Determination Open

Md N. Alam, Jun Yu, Philip Beale, Peter S. Turner, Nicholas Proschogo , et al. · 2020

An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available …

Discriminating distinguishability Open

Stasja Stanisic, Peter S. Turner · 2018

Particle distinguishability is a significant challenge for quantum\ntechnologies, in particular photonics where the Hong-Ou-Mandel (HOM) effect\nclearly demonstrates it is detrimental to quantum interference. We take a\nrepresentation theo…

Quantum simulation of partially distinguishable boson sampling Open

Alexandra E. Moylett, Peter S. Turner · 2018

Boson Sampling is the problem of sampling from the same output probability\ndistribution as a collection of indistinguishable single photons input into a\nlinear interferometer. It has been shown that, subject to certain computational\ncom…

CCDC 1854473: Experimental Crystal Structure Determination Open

Mathieu Denis, Lei Qin, Peter S. Turner, Katrina A. Jolliffe, Stephen M. Goldup · 2018

An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available …

Data from Distinguishability (06-2018) Open

Peter S. Turner, Stasja Stanisic, Alexandra Moylett · 2018

Interference lies at the heart of quantum mechanics and thus its promise of fundamental advantages over non-quantum technologies, with far-reaching ramifications in communication, metrology, sensing, simulation and computation. The nemesis…

Generating entanglement with linear optics Open

Stasja Stanisic, Noah Linden, Ashley Montanaro, Peter S. Turner · 2017

Entanglement is the basic building block of linear optical quantum computation, and as such understanding how to generate it in detail is of great importance for optical architectures. We prove that Bell states cannot be generated using on…

Data from Entanglement in linear optics (07-2017) Open

Stasja Stanisic, Peter S. Turner · 2017

Entanglement is the basic building block of linear optical quantum computation, and as such understanding how to generate it in detail is of great importance for optical architectures. We prove that Bell states cannot be generated using on…

Randomized benchmarking in measurement-based quantum computing Open

Rafael N. Alexander, Peter S. Turner, Stephen D. Bartlett · 2016

Randomized benchmarking is routinely used as an efficient method for characterizing the performance of sets of elementary logic gates in small quantum devices. In the measurement-based model of quantum computation, logic gates are implemen…

Postselective quantum interference of distinguishable particles Open

Peter S. Turner · 2016

We show that it is possible for completely distinguishable particles to interfere postselectively without operating on, or indeed having any knowledge of, the distinguishing degree of freedom. In particular, we find a family of three-mode …

Derandomizing Quantum Circuits with Measurement-Based Unitary Designs Open

Peter S. Turner, Damian Markham · 2016

Entangled multipartite states are resources for universal quantum computation, but they can also give rise to ensembles of unitary transformations, a topic usually studied in the context of random quantum circuits. Using several graph stat…

Testing randomness with photons by direct characterization of optical-designs Open

Jonathan C. F. Matthews, Rebecca Whittaker, Jeremy L. O’Brien, Peter S. Turner · 2015

Generating and characterising randomness is fundamentally important in both\nclassical and quantum information science. Here we report the experimental\ndemonstration of ensembles of pseudorandom optical processes comprising what\nare know…
