Shaping Quantum for Practical Advantage

Quantum hardware is capable of meaningful breakthroughs,
but standard algorithms leave users with a fuzzy picture full of errors.
Phasecraft’s algorithms are 43,000,000x more efficient
than standard approaches.

Magritte: Quantum-Enhanced Materials Modeling

Classical computers model materials using Density Functional Theory (DFT). But DFT struggles with quantum correlations, the very phenomena that determine a material's most interesting properties.

QEDFT blends quantum and classical computing to capture the best from each, resting on advanced quantum algorithms for materials and molecular modeling. Magritte uses quantum algorithms to model materials, the foundation for QEDFT.

Algorithmic efficiency

01

Fewer operations means less exposure to noise. Our 43M× efficiency improvements compress billion-gate workloads into thousands.

Error mitigation

02

We craft noise filters for each computation, rather than rely on generic correction schemes. We preserve what matters and discard what doesn't.

Precise application

03

We limit quantum's role to what it does uniquely well. Classical computation handles the noise-sensitive bookkeeping while quantum handles the correlations classical cannot capture.
