What Entropica Labs does
Entropica Labs Pte. Ltd. is a Singapore-based quantum computing software company founded in 2018 that builds the infrastructure layer between quantum hardware and applications, specializing in quantum error correction (QEC) software for fault-tolerant quantum computing. The company positions itself at the intersection of QEC theory and production software, addressing the programmability gap that prevents fault-tolerant quantum systems from becoming useful at scale. It serves four primary customer segments: quantum computing hardware teams (validating QEC architectures and prototyping logical-qubit designs), software teams (compiling and benchmarking fault-tolerant circuits), research institutions (designing and simulating new QEC codes), and algorithm companies (building applications on hardware-agnostic verified blocks).
The core product is Loom Design, an open-source toolkit that combines Loom (a Python library for QEC code primitives covering surface code, repetition code, five-qubit perfect code, Shor code, and Steane code), Entwine (a free browser-based GUI for lattice surgery operations on surface and repetition codes), the EKA data structure (a novel representation for QEC codes), the Loom Compiler (transforming logical qubit operations into hardware-aware fault-tolerant circuits), and Quilt (packaging programs for quantum control stacks). Complementary products include OpenQAOA, an open-source SDK for the Quantum Approximate Optimization Algorithm, and supporting tools such as the Loom Validator, CliffordSim, and an error-pattern-preserving (EPP) routing protocol. The stack is exposed via integrations with PennyLane, Stim, CUDA-Q, Xanadu Catalyst, Guppy, Mimiq, OpenQASM 3.0, Amazon Braket, qBraid Lab, and Quantum Machines' OPX control platform.
The company operates a hybrid go-to-market model combining enterprise sales to quantum hardware manufacturers and research institutions (quote-based annual subscriptions) with product-led growth through free, open-source tools distributed via PyPI and the web. It has 11-50 employees and is headquartered at 186B Telok Ayer Street, Singapore. To date, Entropica has raised approximately US$5.5M in disclosed funding across a 2020 seed round and a 2023-2024 Series A (US$4.7M co-led by Liftt and Wavemaker Partners, extended by US$800K from State Farm Ventures), supplemented by a Startup SG Tech grant from Enterprise Singapore. Named commercial and strategic relationships include Xanadu, Quantum Machines, Quobly, Yaqumo, Quantinuum, Rigetti Computing, Atom Computing, and BMW. The board includes Dr. Chad Rigetti, former CEO and Founder of Rigetti Computing. Revenue is not publicly disclosed.

Entropica Labs product offering
Product offeringCore offering
Entropica Labs builds open-source and commercial software infrastructure for fault-tolerant quantum computing, centered on quantum error correction (QEC) tools. Its flagship Loom Design toolkit combines the Loom Python library (for building QEC code primitives) and the Entwine browser-based GUI (for visually designing lattice surgery operations), supported by the proprietary EKA data structure for QEC code representation and the Quilt packaging component for executing fault-tolerant programs on quantum control stacks. The company also offers OpenQAOA, an SDK for the Quantum Approximate Optimization Algorithm, and sells licensing/subscription arrangements to quantum hardware manufacturers, software teams, algorithm companies, and research institutions.
Product overview
Entropica Labs offers a unified software infrastructure for programmable fault-tolerant quantum computing. The core product is Loom Design, an open-source toolkit that combines Loom (Python library for QEC code primitives) and Entwine (browser-based GUI for lattice surgery operations), supported by EKA (a novel data structure for QEC codes) and Quilt (for packaging fault-tolerant programs). Additionally, OpenQAOA is provided as a separate open-source SDK specifically for quantum optimization via the QAOA algorithm. The unified stack progresses through three stages: Design (explore and simulate QEC codes), Compile (transform programs to hardware-aware fault-tolerant circuits via Loom), and Deploy (package programs into compact instructions via Quilt).

Entropica Labs competitors and assessment
Company assessmentDirect peers
- Riverlane: Riverlane is a UK-based quantum error correction company building the "Deltaflow" QEC stack and partnering with hardware vendors like Rigetti and IBM. It is the most direct head-to-head competitor to Entropica in the QEC software infrastructure layer.
- Q-CTRL: Q-CTRL builds quantum control infrastructure software (Boulder Opal, Fire Opal) used by hardware teams to improve qubit performance. It addresses an adjacent layer of the fault-tolerant stack (control/error suppression) with similar GTM into quantum hardware vendors.
- Xanadu: Xanadu builds PennyLane and Catalyst for quantum software and is itself pursuing fault-tolerant photonic quantum computing. It is a current Entropica integration partner but also a competing full-stack quantum software/hardware platform.
Emerging players
- Quantum Machines: Quantum Machines provides the OPX quantum control hardware and orchestration platform used by many quantum labs. It is both a current Entropica partner and an adjacent ecosystem player with overlapping ambitions in real-time QEC pipelines.
- Quantinuum: Quantinuum (Honeywell/Cambridge Quantum merger) builds trapped-ion quantum hardware and its own software stack (TKET, lambeq). It is both a current Entropica partner (Singapore R&D centre) and a competitor pursuing integrated fault-tolerant offerings.
- PsiQuantum: PsiQuantum pursues fault-tolerant photonic quantum computing with a fully proprietary stack. While not directly competing today, its billion-dollar scale and fault-tolerant focus make it a potential in-house QEC competitor.
- Atom Computing: Atom Computing builds neutral-atom quantum hardware and has an existing strategic partnership with Entropica. It represents a potential customer and ecosystem partner for Entropica's QEC tooling on the neutral-atom modality.
- Rigetti Computing: Rigetti builds superconducting quantum hardware (Aspen-M series) and is a current Entropica customer for optimization workloads. It is also connected via board member Chad Rigetti and represents a key reference customer for QEC tooling on heavy-hex lattices.
Broad incumbents
- IBM Quantum: IBM's quantum division offers Qiskit and an integrated QEC stack (qiskit-runtime) tied to IBM hardware. It represents the broad incumbent risk: a vertically integrated platform with in-house QEC tooling.
- Google Quantum AI: Google has published seminal surface-code QEC results and is building proprietary QEC tooling tied to its own quantum hardware. It is a benchmark and a long-term competitive threat via in-house capability.
