Ryoushi Research Collective

Quantum withoutthe quantum degree.

A visual workspace where you can learn, build, run and publish quantum experiments. Our first product, Quaggle, takes you from a research question to hardware results.

Our Origin

We didn't find this problem.We lived it.

We came together through quantum research, competitions, and wanting to build things that actually work.

We started as Quantum Buddies — a group built around curiosity, experimentation, and friendship.

As the work grew, we wanted to build more than individual projects — the tools and infrastructure needed to make quantum technology usable outside a research lab.

Our thesis: quantum's next users won't be physicists. They'll be the biologists, economists, and engineers with problems to solve.

That became Ryoushi.

The Problem

Quantum is gated by expertise.

The people with problems quantum could help are rarely the people who can program it.

01

Gap 01 — Learning

Learning Gap

Courses assume you will learn to code circuits first. A chemist has to become a quantum programmer before testing a single idea.

02

Gap 02 — Building

Building Gap

Quantum algorithms live in SDK code. Visual tools stop at single circuits, usually on one vendor's hardware, and moving across providers means rewriting from scratch each time.

03

Gap 03 — Publishing

Publishing Gap

Circuit diagrams and result figures are made by hand, and runs are hard to reproduce, so good work rarely gets reused.

The Solution

Meet Quaggle.Any hardware.

From a research question to hardware results, without writing SDK glue code. Quaggle is a visual, multi-vendor workspace for learning, building, running and publishing quantum experiments.

The Workflow

From circuit to publishable result.

01

Design

Build and parameterise quantum circuits directly in the browser.

02

Run

Execute across simulators and quantum hardware through one interface.

03

Verify

Automatically capture the configuration and metadata behind every run.

04

Publish

Turn experiments into durable projects with results, datasets, and history.

05

Scale

Take validated experiments from small circuits to larger, hardware-scale problems.

Inside Quaggle

Everything aroundthe experiment.

The infrastructure underneath the workflow is designed to make quantum experimentation easier to execute, understand, and share.

Why Quaggle

Less infrastructure.More experimentation.

01

Vendor agnostic

Move between providers without rebuilding the entire workflow.

02

Reproducible by default

Every run retains the information required to understand and reproduce it.

03

Built for real work

Experiments turn into projects and benchmarks — not just logs on someone's laptop.

Ongoing Projects

Projects in progress.

Three systems, each maintained as a public repository: reinforcement-learning-driven error correction, a high-performance simulation engine, and applied machine learning shaped by real hardware constraints.

01

QEC / REINFORCEMENT LEARNING

Syndrome-Net

Quantum error correction as a control problem, not a lookup table.

Surface CodesqLDPCPPOSAC

Syndrome-Net treats decoding and calibration as something an agent can adapt to, rather than a fixed set of rules tuned for one noise profile.

We train the decoder with reinforcement learning — TITANS, Proximal Policy Optimization (PPO), and Soft Actor-Critic (SAC) — instead of hand-tuned heuristics. It supports surface codes, qLDPC, and colour codes, and is built to hold up as NISQ noise drifts rather than staying fixed.

HPC / QUANTUM SIMULATION

QuantumForge

A simulation engine for algorithms too heavy to run in Python.

Rust26 QubitsGQEVQE

QuantumForge is the engine behind our more compute-intensive work — built to close the gap between high-level circuit code and the execution speed needed to iterate on it.

Written in Rust, it simulates 26-qubit statevectors on consumer hardware at roughly 4,000× the speed of a typical Python implementation. That's the difference between waiting on a cluster and iterating locally on algorithms like GQE and VQE.

MACHINE LEARNING / CO-DESIGN

Applied ML

Machine learning shaped by what the hardware can actually do.

Hybrid MLCo-DesignPINNsOptimisation

This work pairs classical machine learning with quantum workflows to tackle high-dimensional, non-convex optimisation problems that neither approach handles well alone.

We study how a given device's noise profile limits which algorithms are actually viable, and apply that to combinatorial optimisation and market simulation. Hackathons and open-source contributions are how we test this against real problems instead of benchmarks we picked ourselves.
