Improving Free-Space Continuous Variable Quantum Key Distribution with Adaptive Optics
Mikhael T. Sayat, Marcus Birch, Michael Copeland +6
A significant performance inhibitor of free-space continuous variable quantum key distribution (CVQKD) is turbulence, which gives rise to wavefront phase and amplitude aberrations.…
Update on the German and Australasian Optical Ground Station Networks
Nicholas J. Rattenbury, Joseph Ashby, Francis Bennet +22
Networks of ground stations designed to transmit and receive at optical wavelengths through the atmosphere offer an opportunity to provide on-demand, high-bandwidth, secure communi…
Mapping Guaranteed Positive Secret Key Rates for Continuous Variable Quantum Key Distribution
Mikhael Sayat, Oliver Thearle, Biveen Shajilal +4
Continuous variable quantum key distribution (CVQKD) is the sharing of secret keys between different parties using the continuous amplitude and phase quadratures of light. There ar…
Testing the postulates of quantum mechanics with coherent states of light and homodyne detection
Lorcan O. Conlon, Angus Walsh, Yuhan Hua +5
Quantum mechanics has withstood every experimental test thus far. However, it relies on ad-hoc postulates which require experimental verification. Over the past decade there has be…
12.6 dB squeezed light at 1550 nm from a bow-tie cavity for long-term high duty cycle operation
Biveen Shajilal, Oliver Thearle, Aaron Tranter +5
Squeezed states are an interesting class of quantum states that have numerous applications. This work presents the design, characterisation, and operation of a bow-tie optical para…
Real-Time Source Independent Quantum Random Number Generator with Squeezed States
Thibault Michel, Jing Yan Haw, Davide G. Marangon +5
Random numbers are a fundamental ingredient for many applications including simulation, modelling and cryptography. Sound random numbers should be independent and uniformly distrib…
Integrated photonic platform for quantum information with continuous variables
Francesco Lenzini, Jiri Janousek, Oliver Thearle +10
Integrated quantum photonics provides a scalable platform for the generation, manipulation, and detection of optical quantum states by confining light inside miniaturized waveguide…
Violation of Bells inequality using continuous variable measurements
Oliver Thearle, Jiri Janousek, Seiji Armstrong +8
A Bell inequality is a fundamental test to rule out local hidden variable model descriptions of correlations between two physically separated systems. There have been a number of e…
Maximizing device-independent randomness from a Bell experiment by optimizing the measurement settings
Syed M Assad, Oliver Thearle, Ping Koy Lam
The rates at which a user can generate device-independent quantum random numbers from a Bell-type experiment depend on the measurements that he performs. By numerically optimising…
Estimation of Output Channel Noise for Continuous Variable Quantum Key Distribution
Oliver Thearle, Syed M. Assad, Thomas Symul
Estimation of channel parameters is important for extending the range and increasing the key rate of continuous variable quantum key distribution protocols. We propose a new estima…
Experimental demonstration of Gaussian protocols for one-sided device-independent quantum key distribution
Nathan Walk, Sara Hosseni, Jiao Geng +9
Nonlocal correlations, a longstanding foundational topic in quantum information, have recently found application as a resource for cryptographic tasks where not all devices are tru…
