MonarQ

Availability: Winter 2025

Login node: to be determined

MonarQ is a 24-qubit superconducting quantum computer developed in Montreal by Anyon Systems and located at the École de technologie supérieure. Its name refers to the monarch butterfly, a symbol of evolution and migration. The capital Q refers to the quantum nature of the computer and to its origins in Quebec. Acquisition of MonarQ was made possible thanks to the support of the Ministère de l'Économie, de l'Innovation et de l'Énergie du Québec (MEIE) and Canada Economic Development (CED).

Technical specifications

MonarQ qubit mapping

The exact technical details will be available at the beginning of 2025, but the specifications should be at least as good as the following:

• 24-qubit quantum processor
• Single-qubit gate, individual: 99.8% fidelity, gate duration: 15ns
• Single-qubit gate, parallel: 99.7% fidelity, gate duration: 15ns
• Two-qubit gate, individual qubit: 95.6% fidelity, gate duration: 35ns
• Coherence time: 4-10μs depending on the state

The exact number of qubits that can be connected and manipulated at the same time, as well as the corresponding fidelities, gate durations, and coherence times, will be available once MonarQ is tested by our team. We will also have results on how it works and performs with various algorithms.

Applications

MonarQ is suited for computations requiring small quantities of high-fidelity qubits, making it an ideal tool to develop and test quantum algorithms. Other possible applications include modelling small quantum systems, testing new methods and techniques for quantum programming and error correction, and more generally, fundamental research in quantum computing.

Quantum computing software

There are several specialized software libraries for quantum computing and the development of quantum algorithms. These libraries allow you to build circuits that are executed on simulators that mimic the performance and results obtained on a quantum computer such as MonarQ. They can be used on all Alliance clusters.

• PennyLane, Python command library
• Snowflurry, Julia command library
• Qiskit, Python command library

The quantum logic gates of the MonarQ processor are called through a Snowflurry software library written in Julia. Although MonarQ is natively compatible with Snowflurry, there is a PennyLane-Snowflurry plugin developed by Calcul Québec that allows you to execute circuits on MonarQ while benefiting from the features and development environment offered by PennyLane.
