🚨 New paper alert: leveraging Classiq’s qubit “garbage collection” to improve quantum execution fidelity and runtime efficiency.
In Classiq’s synthesis engine, auxiliary qubits are automatically reused once they return to the |0⟩ state through uncomputation and qubit lifecycle management.
In our new paper, we show that these same reset points can also be used to detect corrupted executions.
If an auxiliary qubit is not measured in |0⟩ when expected, it’s a strong indication that noise affected the computation.
This enables:
✨Real-time detection of corrupted shots
✨Improved execution fidelity
✨Early termination of faulty executions and immediate restart of a fresh shot
The exciting part is that this capability naturally emerges from the synthesis flow and compiler-managed qubit reuse — without additional complex logic.

Oracle and Classiq Bring Quantum AI Agents to HPC-Scale Quantum Simulation
Quantum software developers need an efficient way to build applications and the computing capacity to test them at scale. In a recent proof of concept, Oracle and Classiq connected those two pieces. Classiq used its quantum expert AI agent as the starting point for generating a quantum portfolio optimization application, and Oracle GPU infrastructure provided the compute capacity for a demanding 36-qubit simulation.

Most quantum walk examples stop at simple lattices.
Real-world networks are…. messier.
Huge congratulations to Dr. Rei Sato! 🥳 His paper on implementing coined quantum walks on complex networks has been officially accepted by Quantum Information Processing!
Using Classiq's Qmod, Synthesis, and Execution capabilities, the study demonstrates an intuitive, end-to-end journey from mathematical modeling to real quantum hardware execution.
The standout feature? Model Reusability. 🔄 Once a model is defined in Qmod, researchers can easily generate circuits for different complex networks just by updating the input graph structure. There is absolutely no need to rebuild quantum circuits from scratch for each dataset, making experimentation faster and more scalable.
Here is the paper:

New Breakthrough in Quantum Error Correction and Syndrome Extraction
A recent paper by Classiq's Gilad Kishony and renowned quantum computing researcher Austin Fowler introduces a new approach for improving syndrome extraction in planar color codes, addressing one of the key challenges in maintaining circuit-level error-correction performance while minimizing hardware overhead.
The work demonstrates a single-auxiliary syndrome extraction circuit that preserves full circuit-level distance and outperforms previous state-of-the-art approaches through simulation.
This research highlights the importance of innovation across the full quantum computing stack, from algorithms and software abstraction to the underlying foundations of fault-tolerant architectures.
Congratulations to Gilad and Austin on this important contribution to the field. We are proud to be a part of it.

Simulating the Physics That Powers Next-Gen Materials
We recently added a quantum simulation of the 1D Fermi-Hubbard model, one of the most important toy models in condensed matter physics for understanding superconductivity, magnetism, and strongly correlated electrons.
Inspired by Google AI Quantum's 2020 experiment (arXiv:2010.07965), the notebook walks through:
Initial state preparation: building the ground state of a non-interacting Hamiltonian as a Slater determinant using a network of Givens rotations.
Trotterized time evolution: quenching the system to the interacting Fermi-Hubbard Hamiltonian and propagating it in time using a first-order Trotter decomposition with Jordan-Wigner mapping.
Observing spin-charge separation: a striking 1D phenomenon where charge and spin excitations propagate at different velocities due to interactions, a regime that's hard to reach with classical methods.
Everything is implemented at a high level with the Classiq SDK, making the algorithm readable and the circuits automatically optimized.
Great work by Roie Dann
Classiq is turning 6
Wishing us a Happy Birthday!
6 years of building, breaking, scaling — and not slowing down.
From a bold idea to a platform used by teams around the world: Designing. Optimizing. Running real quantum software.
No hype. No shortcuts.
Just relentless focus on making quantum actually usable.
Along the way:
We've grown a bit (🐣 💪),
Expanded worldwide (🌎 ),
Created a community pushing what’s possible every day (❤️),
And a platform that keeps getting sharper, broader, and more powerful!
Quantum is no longer “someday.”
It’s being built right now.
And we’re just getting started.
Let’s go 🚀
Documentation That Thinks With You
Exciting news!
We’ve launched the new Classiq documentation experience: same trusted content, now with a cleaner design and smoother, more intuitive navigation.
The biggest addition is AI built directly into the docs, allowing users to ask questions, get contextual explanations, and interact with content without leaving the page.
Combined with a cleaner interface and improved flow, this turns the documentation into a more dynamic workspace, helping developers spend less time searching and more time building quantum applications.
Great work by Alexandre Cesar Ricardo and Lior Gazit.

Proud moment for Classiq!
Our Quantum Error Correction Researcher Gilad Kishony has published a paper with none other than Austin Fowler—and it’s a standout.
Introducing a novel approach that reshapes how we think about quantum error correction.
Here is all you need to know:
Compiling a logical computation for execution via lattice surgery on the surface code is a layered problem rather than a single translation step.
The computation must first be mapped to a topological picture, and that picture must then be embedded as a consistent layout in three-dimensional space-time.
Only after that can the abstract structure be lowered to the physical-qubit level: determining which stabilizers are measured, on which plaquettes or elongated regions, and how those measurements tile the device.
Even once the layout is fixed, much of the work still remains.
The syndrome-extraction circuits implementing each stabilizer measurement must be specified gate by gate, including the ordering of two-qubit couplings, their timing relative to neighboring operations, and the scheduling of resets and measurements.
These choices determine how faults propagate, for example, through hook errors, and therefore directly affect the achieved circuit-level distance and resource overhead. The objective is to reduce this low-level complexity, requiring fewer geometry-dependent conventions and fewer special scheduling cases, without sacrificing the performance metrics that matter in practice, such as preserving distance and keeping the measurement cycle as compact as the hardware model permits.
The diagonal schedule provides a “same recipe everywhere” approach: one fixed ordering for all X-type stabilizers and another for all Z-type stabilizers. This removes the need to specify circuits on a plaquette-by-plaquette basis while still steering hook errors away from logical-operator directions, thereby preserving full circuit-level distance.

Happy World Quantum Day!!!
Why April 14th?
The date points to 4.14, reflecting the first digits of Planck’s constant (4.14 × 10⁻¹⁵ eV·s), one of the most fundamental numbers in physics.
Planck’s constant defines the scale at which the classical world gives way to the quantum one. It sets the “quantum of action,” meaning that energy, momentum, and other physical quantities are not continuous, but come in discrete packets. This idea, introduced by Max Planck in 1900, marked the birth of quantum theory and fundamentally changed how we understand nature.
From that single constant emerges everything from quantized energy levels in atoms to the behavior of photons and ultimately, the principles behind quantum computing.
Today, as quantum technologies mature, the significance of Planck’s constant is no longer confined to theory. It underpins the hardware we build and the algorithms we design.

We’d say the present of computing is looking bright, but in the quantum world, it’s currently in a superposition of being both bright and brilliant.
🏆 The Turing Award has recognized the impact of quantum on our lives.
We can feel a profound sense of pride across the industry today as the 2025 Turing Award is presented to Charles Bennett and Gilles Brassard.
They are the visionaries whose "weird" work proved that sophisticated quantum mechanics is a functional, powerful language for computing.
The foundations they built have already moved us beyond gate-level constraints toward high-level, intent-based design.
Our entire team at Classiq joins the global community in celebrating the founding fathers of quantum information.
Their lifelong dedication is the reason our work is possible today.
