Ryoushi Research Collective

Building the infrastructurefor quantum development.

We build open, reproducible tools for quantum computing — from simulation to real hardware. Our first product, Quaggle, is a vendor-agnostic workspace for creating, running, and sharing quantum experiments.

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.

That became Ryoushi.

The Problem

Quantum development is stuck.

The workflow is fragmented across circuit creation, hardware access, and reproducibility — forcing researchers and builders to spend more time managing tools than creating.

01

Gap 01 — Creation

Fragmented Tooling

Visual tools are often tied to a single vendor or SDK. Every platform speaks a different dialect, making cross-provider building unnecessarily difficult.

02

Gap 02 — Execution

Fragmented Access

Different QPUs require different accounts, APIs, pricing models, and hardware-specific workflows. Running the same circuit across backends becomes a separate engineering effort.

03

Gap 03 — Reproducibility

Experiments Get Lost

Metadata, benchmarking, and result-sharing remain inconsistent. Experiments end up trapped in notebooks and PDFs instead of becoming work other people can verify and build on.

The Solution

One workspace.Any hardware.

Quaggle is a vendor-agnostic workspace for creating, running, and sharing quantum experiments — built around reproducibility from the first circuit to the final result.

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

Compete

Benchmark results and compare performance with other builders.

Inside Quaggle

Everything aroundthe experiment.

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

01

Universal Circuit Layer

Work with OpenQASM, Qiskit, Cirq, and other formats without being locked into one provider.

02

Unified Execution

Route workloads through a common interface for simulators and quantum processing units.

03

Reproducible Runs

Preserve backend, seed, shots, timing, cost, outputs, and configuration with every experiment.

04

Research Publishing

Create project pages containing experiment history, datasets, results, and citations.

05

Benchmarking

Compare accuracy, latency, cost, and shot efficiency across experiments.

06

Talent & Community

Build a public record of experiments, contributions, benchmarks, and technical work.

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.
