Quantum computers promise to revolutionize various research fields and industries through its extraordinary computational capabilities. But why are they special, and what makes the MonarQ computer so unique? Let’s find out together.

 

What is a quantum computer?

Whereas a classical computer processes a single piece of information at a time, a quantum computer processes several pieces of information at once. Why? Because it operates according to the principles of quantum physics, a branch of science that studies matter on an infinitesimal scale.

When we observe phenomena at this small scale, which is around 1 million times smaller than a human hair, particles behave in special ways. Exploiting these quantum behaviors enables us to rapidly solve certain problems that are difficult to solve on conventional computers, through what is known as quantum computing.

 

Why MonarQ? And what will it be used for?

This quantum computer measures over 37 cubic meters. It is surrounded by supercomputers in a data center at the École de technologie supérieure (ÉTS) in Montreal. It is adapted to current research needs and promises to solve problems using new approaches.

 

How does a quantum computer like MonarQ work?

No two quantum computers are exactly alike. Each uses different technologies. What all quantum computers have in common, however, is that they work with qubits, the basic units of quantum information.

COMPONENT FUNCTION MONARQ
Qubits Basic units of quantum information 24 qubits
Control system Manipulating qubits with specific signals Microwave pulses
Measurement system Reading qubit status after calculation Microwave signal analysis
Cryogenics Keeping qubits at very low temperatures to reduce disturbances Helium cryostat keeping qubits at a temperature close to absolute zero, i.e. near -273°C
