Primus for X

Primus for Quantum Mechanics

An autonomous AI researcher for theoretical quantum information. It works on open problems end to end and returns exact, certified results, not numerical approximations. Available to every Primus user today.

01

A specialization inside Primus

Primus for Quantum Mechanics is a mode you select inside Primus. When you start a project, choose the Quantum information specialization and describe the problem.

Primus takes it from there: it sets up the problem, runs the optimization, derives the closed form and writes up the proof.

02

The quantum toolkit, built in

Lean 4 + Physlib QuantumInfo

Formal statements and machine-checked proofs about quantum states and channels.

toqito

Quantum information primitives: states, channels, entanglement and state distinguishability.

cvxpy

Semidefinite programs, the native language of optimal measurements and PPT bounds.

sympy

Exact symbolic algebra for turning numerics into closed forms.

QuTiP

Simulation of open and closed quantum systems.

03

Exact answers, with a certificate

Rather than stopping at a numerical approximation, Primus constructs matching primal and dual solutions to a semidefinite program. When the value you can achieve meets the bound nothing can beat, the formula is certified as the exact optimum, not just a close estimate.

Its derivations are written to be checked, and can be formalized in Lean.

Built for a field of a few hundred specialists

Quantum computing gets plenty of attention, but work like quantum state discrimination under Positive Partial Transpose (PPT) constraints sits at a narrow intersection of convex optimization and quantum information theory. Only a few hundred researchers worldwide work there. Exact results in this area are useful across the field:

SECURITY

Bounding information leakage

Exact PPT bounds limit how much separated parties can learn about a shared state, the standard tool for certifying quantum data hiding.

RESOURCES

Quantifying entanglement

Explicit thresholds for the minimum entanglement a discrimination task needs to succeed without error.

BENCHMARKS

Analytic test cases

Problems with broken symmetries rarely have closed forms. Exact solutions become benchmarks for broader channel discrimination algorithms.

05

Working with quantum teams

We want to work directly with quantum companies and research teams on the problems slowing their progress. If that’s you, hello@lab.cloud.

The frontier should belong to more people, not a few closed labs.
