At IBM, work is more than a job - it's a calling: To build. To design. To code. To consult. To think along with clients and sell. To make markets. To invent. To collaborate. Not just to do something better, but to attempt things you've never thought possible. To lead in this new era of technology and solve some of the world's most challenging problems. IBM is a leading cloud platform and cognitive solutions company. Restlessly reinventing since 1911, we are the largest technology and consulting employer in the world, with more than 350,000 employees serving clients in 170 countries. With Watson, the AI platform for business, powered by data, we are building industry-based solutions to real-world problems. For more than seven decades, IBM Research has defined the future of information technology with more than 3,000 researchers in 12 labs located across six continents.

Rigetti Computing is building the world’s most powerful computers to help solve humanity’s most pressing and important problems. These systems will perform computations that today’s fastest supercomputers are incapable of — unlocking entirely new classes of problems and offering a direct path to solutions. We believe quantum computing is going to significantly affect health care, how we treat disease, how we generate energy, and how we feed humanity. Our superconducting quantum computing systems are available over the cloud via Rigetti Quantum Cloud Services. We were founded in 2013 by Chad Rigetti. We are located in Berkeley and Fremont, California, and have employees based all over the world.

AOSense, Inc. is a leading developer and manufacturer of quantum technologies. We build systems and sub-components including atom optic devices for precision navigation, gravity measurement, timekeeping and quantum computing. Our capabilities include gyroscopes, accelerometers, inertial measurement units (IMUs), gravimeters, gravity gradiometers, and atomic frequency standards. A variety of quantum technologies such as computing, magnetometry and quantum communication benefit from our development of sub-components such as compact and stable laser systems, atom sources, and a variety of hardware. AOSense was formed in 2004 by Brenton Young and Mark Kasevich to spin-off innovative research developed at Stanford University, joined by Jim Spilker as Chairman. In 2006, AOSense was awarded its first prime contract from DARPA to design, build, and test a gravity gradiometer and single axis accelerometer/gyroscope. Since then, AOSense has successfully designed and built state-of-the-art cold atom technology for numerous government sponsored programs funded by DARPA, Air Force, Army, Navy, NASA, NSF, DTRA, and the intelligence community. AOSense is an employee-owned company.

Located in Boston, QuEra Computing is a maker of advanced neutral-atoms based quantum computers, pushing the boundaries of what is possible in the industry. Founded in 2018, the company is built on pioneering research recently conducted nearby at both Harvard University and MIT. QuEra is building the industry’s most scalable quantum computers to tackle useful but classically intractable problems for commercially relevant applications. Our signature 256-qubit machine, Aquila, the largest publicly-accessible machine in the world, is available now for general use over the Amazon Braket cloud.

Atomionics is a Singapore based VC-backed startup building quantum sensors for Navigation and Resource Exploration. We measure gravity, acceleration, and rotation 1000x better than the state of the art. Atomionics sensors can build a complete map of the underground, thus help pinpoint underground structures like tunnels and bunkers, and predict earthquakes, provide precise navigation, and build a universal positioning system that works everywhere – underground, underwater, and even in space. We have deep expertise in bringing complex technologies from a lab environment to the dynamic real world. At Atomionics we like to cultivate a casual and friendly environment. We are a small focused group in a high-energy environment. The core of what we are building is called cold atom interferometry, where we cool down atoms to micro Kelvin temperatures by shooting lasers at them. Our team has over 30 years of combined relevant research experience. This allows us to measure the forces acting on them precisely. Due to the complexity of our work, our employees get to interact with other interdisciplinary domains such as Electronics Engineering, Mechanical Engineering, Physics, and Software Engineering. Our company likes to treat our work as a “gym for our minds”. In addition, we are backed by some fantastic investors from the private and public sectors, such as Wavemaker, SGInnovate, Capvista, 500startups, and other prominent angels.
