Collaborate with QSI
QSI's long established expertise in software and information processing capabilities of quantum computing and communication technologies places it in a unique position in Australia. QSI’s research strengths in software and theory complement not only our hardware and experimental activities, but also the research taking place in frontier quantum initiatives across the globe.
Here are some of the ways we partner with industry, academia and other world-leading quantum tech communities:
Designing quantum architectures
We work to formulate the next generation of quantum architecture design that promises to scale from hundreds to thousands to millions of physical qubits.
Working with multiple experimental groups to evolve their hardware systems beyond scalability bottlenecks, including Ion Trap designs targeted at the multi-million qubit level in collaboration with Universal Quantum and the University of Sussex, and superconducting qubit microarchitectures in collaboration with Tokyo University of Science and RIKEN. Multiple architecture designs over the past decade have been adopted by start-ups and national programs, most notably Moonshot Research & Development Japanese National Program. These blueprints form a basis of long-term strategic R&D into quantum computing for each.
Quantum benchmarking – Bench-Q
Performance analytics are a critical component of the classical information processing industry. Creating performance benchmarks for quantum algorithms is likewise critical. As part of DARPA’s Quantum Benchmarking Program we are developing the Bench-Q platform.
With automatic error-corrected compilation from high-level circuits written in major languages such as QISKIT, Cirq or Q#, the Bench-Q platform is designed to give detailed breakdowns on the number of qubits and the time needed to complete a given algorithm. Collaborating with major hardware providers such as IonQ, Rigetti, SQC and PsiQuantum, performance analytics can be tailored to each hardware platform such that rapid feedback on hardware resources can be provided to both quantum hardware and software developers.
The goal is to become the de-facto standard framework in benchmarking and quantum performance analytics.
QSI is a key partner in DARPA’s Quantum Benchmarking Program, developing tools for fault tolerant resource estimation based on core algorithmic subroutines alongside Zapata, Aalto, UTD and IonQ and guidestars for modular quantum computing with Rigetti, USC, Aalto.
Quantum Sneakernet: Backbone to the quantum internet
We are working on a fundamentally new model of quantum communications that leverages the concept of physical hard drives. Quantum sneakernets can be sent anywhere. Rather than storing and transmitting quantum information, though, the sneakernet transports entanglement itself. Entanglement becomes the resource – these entangled states can be used as virtual communication channels to transmit quantum information at the same speed as the classical sidechannel used in quantum teleportation protocols.
Consequently, we can build a quantum sneakernet with the same latency as the classical internet. Range, rate and fidelity of the networking links becomes purely a question of how many devices can be fabricated and at what cost. Bringing new cities and countries into the network simply depends on where we can ship the units (no other infrastructure is needed).
The quantum sneakernet is a unique solution for Australian quantum communications.
