Quantum development hub

Build quantum. Know the bill.

QDE is a curated hub for quantum development: the real editors, SDKs, and playgrounds worth your time, plus a circuit-to-estimate bridge that parses your OpenQASM in the browser and frames what it would cost at fault-tolerant scale. QDE does not pretend to run your circuit - it points you at the things that do, and prices what you are building.

The real tools

Curated, current, and linked straight to source. No affiliate anything.

SDK

Qiskit (IBM)

The most-used quantum SDK: circuits, transpilation, primitives, and access to IBM's real hardware via Qiskit Runtime. qiskit.org · IBM Quantum Platform

Cloud

Amazon Braket

Managed access to IonQ, Rigetti, IQM, QuEra hardware plus on-demand simulators, billed through AWS. aws.amazon.com/braket

SDK

PennyLane (Xanadu)

Quantum machine learning and differentiable programming, plugs into PyTorch/JAX and most hardware. pennylane.ai

Design

Classiq

High-level quantum algorithm design: model at the functional level, synthesize down to circuits. classiq.io

Estimate

Azure Quantum Resource Estimator

Microsoft's estimator for fault-tolerant resource counts - the closest production tool to our calculators. quantum.microsoft.com

Format

QREF + Bartiq (PsiQuantum)

Open resource-estimation format and symbolic compiler for hierarchical quantum programs. QREF · Bartiq

Circuit-to-estimate bridge

Paste OpenQASM 2.0. The bridge counts your logical qubits and gates locally (nothing is uploaded), then frames the fault-tolerant bill honestly: NISQ-scale circuits are cheap; the expensive future is error-corrected, where T-gates dominate and every logical qubit costs roughly a thousand physical ones.
