What is quantum control engineering?

Quantum technology, harnessing quantum physics as a resource, is likely to be as transformational in the 21st century as harnessing electricity was in the 19th. But turning this potential into practical outcomes requires us to overcome the extraordinary fragility of quantum devices. The impact of noise and interference on quantum hardware represents a true Achilles heel for quantum technology.

Q-CTRL allows you to do more with the whole range of quantum technologies, from quantum computers to quantum sensors, by giving you access to the powerful techniques that make airplanes fly, robots walk, and cars drive themselves – control engineering.

From quantum algorithms to low-level firmware, our products help users extract more performance from quantum hardware, whatever their application. Q-CTRL helps put you in control of your quantum future.
