Diraq is building quantum computers based on modified silicon transistors, the technology best suited to achieving utility scale, when value far outweighs cost. Diraq’s mission is to become the global leader in the development of utility-scale quantum computing with millions of qubits on one silicon chip. Diraq’s silicon technology is designed to be integrated into standard data centers. It runs on a single quantum chip, packaged together with classical electronics that operate at cryogenic temperatures, connected to supporting electronics at room temperature. Founded in Sydney, Australia, Diraq has operations in Sydney and Melbourne, Australia, and is expanding rapidly in the United States with operations in Palo Alto, Los Angeles, Boston, and Chicago.

The ever-growing technological advances in computing, communication, and sensing all depend on photonics. PINC is building a transformative integrated platform to meet these needs and make that future possible. For decades, photonic chips have been missing their equivalent of the transistor, the compact, scalable nonlinearity that fueled the electronics revolution. PINC’s NanoPPLN platform, born from groundbreaking research at Caltech, delivers that missing piece and brings the power of nonlinear optics from large optical tables to chips, opening new frontiers in optical sensing, quantum technologies, AI, data centers, and beyond.

Pioniq is a deeptech start-up emerging from the historical “ESPCI” school in Paris known for having graduated famous French researchers like Paul Langevin and Frédéric Joliot-Curie and hosted no less than 6 Nobel prizes. Following a long-standing tradition in the discovery of innovative materials, the Pioniq team aims at developing and selling disruptive energy storage solutions based on quantum materials. At Pioniq we are convinced that energy storage technologies need not only to be efficient but also perfectly in line with the greatest human challenge of all-time concerning Earth climate and must respond to sustainability and recyclability criteria. After years of fundamental research in quantum solids, the team is proud to present a new class of Li-free, Co-free, Ni-free solid-state energy storage devices powered by quantum matter phase transitions. The Pioniq solution departs from existing technologies for energy storage as it is composed of abundant, recyclable and price-stable elements based on solids derived from the well-known perovskite family.

We build Programmable Quantum Simulators and Quantum Computers made of 2D and 3D Atomic Arrays. Neutral atoms trapped in optical tweezers and addressed with laser beams are ideal indistinguishable quantum systems to realize superposition and entanglement, at the heart of powerful Quantum Information Processing. It is a highly scalable platform, benefiting from tens of years of development which has brought some of contemporary physics​ most spectacular achievements: Bose-Einstein condensation, cavity quantum electrodynamics, etc... We develop the lasers, the vacuum technology, the electronic controls and the software stack to make the individual atoms accessible to quantum programmers worldwide.
