Reference

This reference guide provides technical specifications, limits, and detailed configuration information for QDE workspaces and development environments.

Workspace Specifications

Infrastructure

Cloud Platform: QDE workspaces run on Amazon Web Services (AWS) infrastructure, providing reliable and scalable cloud computing resources.

Computing Resources: Each workspace provides dedicated CPU cores and memory optimized for quantum computing workloads.

Storage: 10 GB of persistent storage in /home/coder for your development files, installed packages, and workspace configuration.

Quantum Simulation Capabilities

Qubit Simulation: QDE workspaces support quantum circuit simulation up to approximately 30 qubits, with 20 GB of memory available for simulation workloads.

Simulation Performance: Actual simulation capabilities depend on:

  • Circuit depth and gate complexity
  • Entanglement patterns in your quantum circuit
  • Available memory after loading libraries and data
  • Concurrent processes running in your workspace

Resource Estimation: When performing resource estimation, Workbench can analyze quantum algorithms requiring thousands of qubits, as it performs analytical resource estimation rather than full circuit simulation.

Simulation Scaling

Quantum simulation memory requirements grow exponentially with qubit count. Each additional qubit roughly doubles memory usage. For algorithms requiring more qubits than can be simulated, turn off the simulator and use the Workbench resource estimation tools instead of full simulation.

Operating System Environment

Base System: Ubuntu 22.04 LTS with long-term support and security updates

Python Environment: Python 3.12+ with scientific computing stack pre-installed

Development Tools: Git, curl, wget, vim, nano, and standard Unix utilities

Container Runtime: Docker support for containerized application development
