Quanterall is a Bulgarian quantum computing research lab founded on March 23, 2003, after the original vision was formed in 2002 at the Joint Institute for Nuclear Research in Dubna. Today our work focuses on quantum algorithms, simulation tooling, quantum-AI experiments, and BEAM-based runtime models for educational and research use.

Since 2009 we have worked deeply with Erlang and later Elixir on the BEAM virtual machine, taught students and engineers through our internal academy and with three universities, and built distributed systems that must remain reliable under load. The live demos on this page come from that practical foundation: real simulation backends implemented on BEAM, not just future-facing brand language.

Twenty-three years of groundwork.
Now applied to quantum research.

Quanterall was founded on March 23, 2003 in Varna, Bulgaria, after the original quantum vision and the name "Quanter-all" were conceived in 2002 at JINR in Dubna. That story matters — but the more important point is what exists now.

Since 2009 the company has built deep experience in Erlang and later Elixir on BEAM, trained students and programmers through its internal academy and with three universities, and developed reliable distributed systems across multiple industries. The current quantum effort grows directly out of that engineering practice: algorithms, simulations, hybrid runtime experiments, and public demos that make the work inspectable.

// Current Direction

Quantum research.
Operationally grounded.

This is not a speculative rebrand. Quanterall is turning long-standing distributed-systems expertise into concrete quantum work: algorithms, simulation backends, hybrid quantum-classical workflows, and educational research tooling designed for real collaboration.

Quantum Algorithms & Simulation
Designing and testing quantum algorithms together with simulation tooling that makes circuit behaviour inspectable. The emphasis is on executable models, educational clarity, and research artefacts that can be extended rather than merely described.
Quantum AlgorithmsError CorrectionVariational MethodsNISQFault Tolerance
Quantum-AI & Hybrid Systems
Exploring how quantum routines, classical orchestration, and BEAM-style concurrency can work together in practical systems. This includes quantum ML experiments, hybrid evaluation flows, and distributed runtime designs for research use.
Quantum MLQNNsKernel MethodsQuantum AdvantageOptimisation
Why now?
The timing matters, but the real reason this move is credible is operational continuity.

Since 2009 Quanterall has worked with Erlang and later Elixir on BEAM to build systems with very large numbers of concurrent processes, strong fault isolation, and dependable runtime behaviour. The company has also trained students and programmers through its internal academy and with three universities — turning distributed systems knowledge into something teachable and repeatable.

That background maps naturally to quantum simulation and hybrid orchestration. The public demos on this page, implemented on BEAM, are early proof of work. The point is not that the future has already arrived; the point is that Quanterall is building from proven engineering practice into quantum algorithms, simulators, and research collaborations right now.
// Research Areas

Current workstreams,
plus two BEAM-based exploratory tracks

R-01
Quantum Algorithm Design
Current work includes algorithm design and simulation studies around search, sampling, optimisation, and benchmark circuits that can be executed, compared, and taught. The aim is to create research artefacts that are inspectable, not just conceptually elegant.
R-02
Quantum Error Correction & Fault Tolerance
Studying repetition, CSS, surface, and related code families through simulation and explanatory tooling, with emphasis on making logical encoding, syndrome extraction, and correction pathways understandable for researchers and advanced learners.
R-03
Quantum Machine Learning
Exploring quantum-enhanced learning with a practical bias: variational circuits, kernel constructions, and hybrid evaluation workflows that help distinguish genuine promise from hype in quantum-AI claims.
R-04
Quantum-Classical Hybrid Architectures
Designing orchestration layers where classical services, distributed runtimes, and quantum routines cooperate in one workflow. This includes BEAM-friendly designs for simulation control, message passing, scheduling, and hybrid execution.
R-05
Post-Quantum Cryptography Migration
Studying the practical migration questions raised by quantum progress: post-quantum cryptography, system architecture changes, and how high-reliability organisations prepare for a mixed classical/quantum future.
// Exploratory Research — BEAM-Informed Directions
Actor-Model Metaphors for Quantum Entanglement

Investigating whether the actor model on BEAM — with process isolation, supervision, and asynchronous messaging — can serve as a useful teaching and prototyping metaphor for multi-party entanglement protocols. This grows directly out of Quanterall's Erlang background and is intended as an educational and exploratory bridge, not as a claim of physical equivalence.

Distributed Runtime Metaphors for Quantum Teleportation

Exploring whether BEAM-style distributed process communication can help prototype the classical control flow around teleportation: Bell-state measurement, classical signalling, and corrective operations. The value here is pedagogical clarity and system design experimentation, especially for students and engineers already familiar with Erlang or Elixir.

// Live Quantum Demos

Live quantum demos.
Built on BEAM.

These demos are public proof of work: educational and research-oriented quantum circuit simulations served from BEAM backends implemented in Erlang and Elixir. They return live measurement data so visitors can inspect real outputs rather than static mockups.

// Core Quantum Algorithms
Q-01
Bell State
Two-qubit maximal entanglement. Measures the |Φ⁺⟩ Bell state — equal superposition of |00⟩ and |11⟩. The simplest proof of non-classical correlations.

Q-02
Quantum Teleportation
Transfers an unknown qubit state across two classical bits using a shared Bell pair. No quantum channel required after entanglement.

Surface-3 Code
Distance-3 surface code on a 3×3 grid — the leading candidate for fault-tolerant logical qubits on near-term hardware. Detects and corrects any single-qubit error.
Run →

Each endpoint returns JSON with circuit metadata, shot counts, and measurement histograms. These demos are designed as inspectable research primitives and teaching tools; append ?shots=N to control simulation depth.

// The Physics

Physics first.
Engineering second.

Superposition, entanglement, and interference are not just concepts on the page. They are the physical ideas behind the simulations, teaching materials, and runtime experiments Quanterall is building today.

Superposition — qubits process exponentially large state spaces simultaneously, enabling parallelism inaccessible to classical bits.
Entanglement — correlated quantum states allow non-local information sharing that powers quantum communication and key algorithms.
Interference — quantum amplitudes cancel wrong answers and reinforce correct ones — the heart of quantum algorithmic design.

23 years of groundwork.
Now applied to quantum.

2002 ✦
Conception at JINR
While working at the Joint Institute for Nuclear Research (Dubna), the founder — a physicist with background in quantum field theory — invents the name "Quanter-all" and the quantum computing vision together with two colleagues. The idea is born, but the technology is not ready.
2003
Founded in Varna
Quanterall is formally established as the vehicle to pursue the 2002 vision when the time becomes right.
2003–2016
Large-Scale Systems Era
Enterprise and industrial software across European markets, with growing focus on distributed systems, reliability, and high-uptime platforms. From 2009 onward, Erlang and BEAM became an important part of that engineering practice.
2016–2020
Research-Oriented Specialisation
Deeper focus on mathematically rigorous, reliable software architecture, alongside ongoing education of students and programmers through Quanterall's internal academy and university-linked teaching.
2020–2025
Projects across Many Domains
Work across healthcare, logistics, finance, bioinformatics, communications, insurance, and other domains — plus continued Erlang/Elixir practice and distributed runtime experimentation relevant to quantum simulation.
2026 ✦
Return to the Original Vision — Year 23
Full commitment to quantum computing and quantum-AI research on the 23rd anniversary. The circle closes.
"Since 2009, Erlang and BEAM have been part of the preparation."
"The live demos are not decoration. They are part of the research tooling."

The name Quanterall was never arbitrary. "Quanter-all" — all-in on quantum — was chosen in 2002 at JINR in Dubna as a deliberate statement of intent. What followed was not a straight line into quantum hardware, but it was relevant preparation: decades of distributed systems work, deep experience with Erlang and Elixir on BEAM since 2009, and long-running education of students and programmers through an internal academy and collaborations with three universities.

That is why the present-day claim is intentionally modest and concrete. Quanterall is not claiming a finished quantum future. It is showing a credible transition into quantum algorithms, simulations, and research tooling backed by engineering practice that already exists.
