Now, it’s time for Coherence, the quantum executive summary, where I take a moment to highlight some of the business impacts we discussed today in case things got too nerdy at times. Let’s recap.
Mirella Koleva was working on quantum photonics in 2014 when she met the eventual cofounder of Quantopticon. Her soon-to-be partner was working on a framework that could describe light-matter interactions. The two realized this model could help create next-generation quantum photonic devices. Mirella developed code to automate the use of the system and broaden its application to different types of problems.
Quantopticon believes that photonic quantum computers will prevail as a leading type of architecture for reasons including room-temperature operation, long decoherence times and compatibility with telecom equipment.
The photonic systems have to overcome some engineering challenges to become a prevalent technology. One issue is effective memory that could store quantum photonic qubits until they’re addressed. Another is improving the performance of support components.
To help accelerate the solving of these challenges, Quantopticon created software that can help design qubits, single-photon sources and quantum logic gates. It’s called Quantillion, and you can think of it as quantum CAD. It can render very realistic simulations of devices such as photonic structures on a chip. In the future, they imagine being able to model complete quantum-photonic integrated circuits.
For now, modeling individual components is possible. The software can model material qubits, which are optical transitions in mutual systems: You may have heard of cold atoms, as an example. Quantillion also helps with localized spins in quantum structures, quantum dots and spin qubits in silicon. The software is designed to be useful to many types of systems.
A lot of criteria go into qubit quality. Quantillion can help with improving coherence times, purity, brightness, efficiency and fidelity. The hope is to improve the quality of components and speed up production.
Quantopticon is also using the tool to develop satellite-based quantum communications for the European Space Agency, showing its versatility.
Quantum memory is still in its infancy, and Quantillion can help develop solid-state and ion waveguide versions of memory. Improving quantum memory could help universal photonic quantum computing but also will enable quantum repeaters to grow quantum communication networks to usable sizes. Interconnect may benefit from these networks too, letting systems act as one large quantum computer from a distance.
Quantopticon hopes to have the Quantillion tool available in the cloud eventually, with even better visualization capabilities. For now, it’s a download. Check out the link in the show notes if you’re interested.
