The Singapore company writing the software that makes fault-tolerant quantum computers programmable.
Everyone is racing to build more qubits. Entropica Labs bet, back in 2018, that the harder problem would be teaching those qubits to behave.
Quantum computers are famously error-prone. A qubit forgets its own state, drifts, and picks up noise from the world around it. To run a useful calculation, a machine needs quantum error correction (QEC): a way to spread information across many physical qubits so that mistakes can be caught and undone faster than they pile up. This is the discipline of fault tolerance, and it is widely considered the gate every quantum computer must pass through before it does anything commercially serious.
The catch is that fault tolerance has been brutally hard to program. Designing error-correcting codes, injecting them into a circuit, and translating the result down to a specific chip's physical qubits has, until recently, been the work of specialist researchers writing bespoke code for one machine at a time.
Entropica Labs exists to change that. The company describes itself plainly: it builds the infrastructure layer between quantum hardware and applications, closing the "programmability gap" that keeps fault-tolerant quantum computing from becoming useful at scale. Its mission statement is refreshingly concrete - "make fault-tolerant quantum computers programmable, and then use them to tackle the world's hardest computational problems."
Founded in Singapore by Tommaso Demarie, Ewan Munro and Joaquin Keller, the roughly 21-person team has spent years turning a research-grade craft into something closer to a software workflow: design a code, verify it, compile it, ship it to hardware.

The product names - Loom, Entwine, Quilt - all borrow from weaving, a nod to threading error correction through a quantum program. Together they cover the full lifecycle: design, compile, deploy.
A graphical, browser-based IDE for designing lattice surgery on surface and repetition codes. Build, run and analyse QEC circuits on a visual canvas - no special hardware required. It is Entropica's on-ramp for anyone learning error correction.
Takes a logical quantum computation and turns it into a fault-tolerant, hardware-aware circuit - automating code design, error-correction injection and physical-level translation. At its heart is EKA, a hardware-agnostic data structure that carries QEC context across every layer as a single source of truth.
Packages the fault-tolerant programs Loom produces into compact, contextual instructions that partner control stacks can unpack and run on real machines - the last mile between compiler and qubit.
The company's earlier open-source SDK for the Quantum Approximate Optimisation Algorithm, with built-in access to IBM Quantum, Rigetti QCS, Amazon Braket and Azure Quantum - the project that put Entropica on the community map.
Entropica sells to the people building the machines: quantum hardware teams, control-stack vendors, algorithm companies and research institutions. Named collaborators include Xanadu, Quantum Machines, Rigetti, Quobly and Yaqumo, with platform integrations reaching developers through qBraid and PennyLane/Catalyst.
Raw qubit counts are misleading - a million noisy qubits you can't correct is an expensive space heater. Entropica removes the specialist bottleneck by automating how error-correcting codes are designed, verified, compiled and deployed, so hardware teams don't rebuild fault tolerance from scratch for every chip.
Rather than picking a hardware bet, Entropica is deliberately hardware-agnostic. Its EKA data structure lets one representation flow from algorithm down to physical qubits across different architectures, positioning the company as connective tissue that many hardware makers integrate with instead of a rival to any of them.
It sits alongside other error-correction and control specialists - Riverlane, Q-CTRL and in-house QEC teams at the hardware giants - but focused squarely on making fault tolerance a programmable, cross-vendor workflow. A former Rigetti CEO on the board signals where value is migrating: from qubits to the software that makes them trustworthy.
Entropica runs a B2B software model: license the fault-tolerance tooling to industry, while free and open-source entry points (Entwine, OpenQAOA, Loom's primitives) grow adoption and developer mindshare.
Tommaso Demarie, Ewan Munro and Joaquin Keller start the company to build quantum software infrastructure.
Backed by Wavemaker Partners and others within the Centre for Quantum Technologies ecosystem.
Open-source, multi-backend SDK for the QAOA optimisation algorithm, including a package for Rigetti's Quantum Cloud Service.
Round led by LIFTT and Wavemaker Partners to fund software development and hiring.
The former Rigetti CEO joins the board as Entropica integrates EKA with PennyLane and Catalyst.
A global QEC design competition launches, and Loom is demonstrated with major partners across industry events.
A government-witnessed MOU with Yaqumo, an architectural co-design deal with Quobly, and Loom lands on qBraid Lab.
Loom's core data structure is named from the Sanskrit word for "one" or "first" - it acts as a single source of truth across the whole quantum stack.
The company's tagline, "Per Aspera ad Quantum, Per Quantum ad Astra," reworks the classic "through hardships to the stars."
Entwine runs entirely in a browser, letting anyone design lattice surgery for error-correcting codes without touching real hardware.
Loom, Entwine, Quilt - the product names all come from textiles, a running nod to threading error correction through a program.
It builds software that sits between quantum hardware and applications, letting engineers design, validate, compile and deploy fault-tolerant quantum circuits with quantum error correction.
It was founded in Singapore in 2018 by Tommaso Demarie (CEO), Ewan Munro and Joaquin Keller.
The Loom framework for automating error correction, the Entwine visual IDE for designing lattice surgery, the Quilt packager for control stacks, and the earlier OpenQAOA optimisation SDK.
