TJM: A scalable, open-source algorithm that allows standard CPUs to simulate massive (1000+ qubit) noisy quantum systems by combining stochastic sampling with tensor network compression.

Project TJM: The "Quantum Zip File" Protocol

Democratizing quantum simulation by running supercomputer-scale problems on laptop-scale hardware.

What is it? The Tensor Jump Method (TJM) is a new algorithm that allows standard computers (like the one you are using now) to simulate massive, "noisy" quantum systems that previously required supercomputers. Why it matters? Real-world quantum computers are "noisy". They interact with heat and radiation, causing errors. To build better ones, we need to simulate this noise. Previously, this was mathematically impossible for large systems because the data required grew exponentially. TJM fixes this, simulating up to 1,000 quantum bits (qubits) on a regular Intel processor consumer-grade CPU (Intel i5-13600KF)

The code is open-source (MQT-YAQS), meaning you can download and run it today.
