Quantum algorithms
We design algorithms that use superposition and interference to beat the best classical methods. We also publish the resource estimates that show when they will run on real hardware.

01 — What we do
We write the software layer between physics and outcomes.
Quantum software & compilers
We build the languages, compilers and testing tools that turn an idea into a circuit a machine can run. Most of it is open source.
Learn moreApplied research
We work with chemists, materials scientists and engineers on specific problems. The aim is to find where a quantum computer gives a measurable advantage, and to say so plainly when it does not.
Learn more02 — Why quantum, why now
Some problems are written in the language of nature.
Molecules and materials follow quantum rules. A classical computer has to approximate them. A quantum computer can follow the same rules directly. Hardware is improving fast, and the software has to be ready first.
Qubit
A bit with a direction
A classical bit is 0 or 1. A qubit is a direction on a sphere. The top means 0, the bottom means 1, and every other point is a mix of both.
Superposition
Both, until you look
Until it is measured, a qubit holds both possibilities at once, each with a weight. Measuring it gives a single 0 or 1. Algorithms arrange those weights so the right answer becomes the likely one.
Entanglement
Correlated by design
Entangled qubits share one state. Measure one and you learn about the other. This is what lets a few hundred good qubits describe more states than there are atoms in the universe.

Qubit · drag the arrow
The qubit points between 0 and 1. Measuring it forces a choice, with odds set by its direction.
Entangled pair: measure one, and the other is no longer a coin toss.
03 — Impact
Where quantum changes the world.
Each area has a horizon. It is our honest estimate of when quantum methods could matter in practice, and we update it as hardware and algorithms improve.
Drug discovery & molecular simulation
Simulate how a drug binds to its target from first principles, before anything is made in a lab.
Horizon: 5–10 yrs
New materials & batteries
Predict the properties of new catalysts and electrolytes for denser, safer batteries.
Horizon: 5–10 yrs
Climate & energy optimization
Balance power grids and model carbon capture chemistry at a level of detail out of reach today.
Horizon: 10+ yrs
Cryptography & security
Large quantum computers will break today's public-key encryption. We help teams move to post-quantum methods now.
Horizon: Migration starts now
Logistics & optimization
Find better routes and schedules for fleets, factories and supply chains with thousands of moving parts.
Horizon: 5–10 yrs
Finance & risk modeling
Estimate risk across many scenarios with fewer samples than classical Monte Carlo methods need.
Horizon: 5–10 yrs
04 — Our approach
From a whiteboard to a working partnership.
Step 1
Research
Start from a hard question and the mathematics behind it. Work out what a quantum method could gain, on paper first.
Step 2
Prototype
Write the algorithm, run it on simulators and today's hardware, and measure the gap to the best classical approach.
Step 3
Open-source
Publish the paper and the code, so other researchers can check our results and build on them.
Step 4
Partner
Take proven methods to companies with real data and real constraints, and develop them together.
05 — Open research
Published openly, reproducible by default.
