developing software for simulating quantum-photonic devices

"With such a simulation tool, my team could model the behavior of a wide variety of new artificially constructed materials & their modification of the behaviors of current & future optical systems."

"Quantillion enables the user to explore new combinations of device configurations and pulse excitations, opening the way to ground-breaking quantum optical phenomena."

"I was impressed by the accuracy and generality rendered by their theoretical methodology & the additional capabilities that it offers, such as modelling ultrafast nonlinear dynamics & quantum-optical effects."

"The project is very timely, as we are beginning to see examples of engineered single photon source devices moving towards commercialisation, and so there is a real prospect that the development suite (Quantillion) could help to advance UK quantum technologies towards economic and social benefit."

"With its rigorous description of femtosecond and even sub-cycle pulses, Quantillion will allow us to model coherent regimes of operation. As the software computes the time evolution of the quantum system, and in particular, the (polarised) time-resolved photoluminescence trace, we can compare the simulations with our experiments and infer important material parameters from this."

"I can see clearly that their software will be extremely useful to academics and commercial companies alike, as it will allow experimentalists to predict outcomes without experiments, leading to a reduction in wasted time and laboratory resources."

"Computational modelling is an essential aid to the design of quantum-photonic devices for applications in quantum technologies. One of the major obstacles standing in the way of accurate modelling is how to simulate and control realistic open quantum systems and devices efficiently. Remarkably, within their software, Dr Slavcheva and Dr Koleva address and tackle this salient issue by developing master equations, based on self-consistent solution of vector Maxwell and density matrix equations in the real-pseudospin vector geometrical picture."

"As Head of Optical Network Research at BT, I am increasingly conscious of the mounting complexity of quantum devices and networks in the optics and photonics industry. The next stage of translating benchtop demonstrators into commercial, streamlined large-scale manufacturing will require the assistance of advanced design and modelling tools for quantum technologies [...]. Quantopticon is addressing precisely this need with its sophisticated quantum-photonic simulation software Quantillion. Quantopticon is developing key enabling technology, which I can envision soon becoming of pivotal importance for large-scale manufacturing of next-generation quantum communication systems."

"Thanks to Quantopticon’s unified electromagnetic and quantum-mechanical model, we at Nu Quantum are convinced that Quantillion will support us in developing better quantum optical interfaces for our collaborators and customers with a dedicated software for quantum application in a single package. Quantillion has unique capabilities that will enable us to achieve maximum light extraction, optimise coupling to fibres, and transmit light adiabatically from qubit to fibre to chip. Quantillion is capable of simulating any given quantum system, regardless of the number of energy levels it contains and dielectric Bragg mirror it involves. This means it is applicable to our entire range of systems, which we find very valuable."
