Michael Biercuk, The Q-CTRL Founder Whose Error Suppression Software Runs on IBM, Rigetti and Diraq Machines

Michael Biercuk is an experimental physicist who founded Q-CTRL in Sydney in 2017 and still runs it as chief executive. He also holds a chair in quantum physics at the University of Sydney and directs its Quantum Control Laboratory. The company sells software that shapes the control signals sent to a quantum computer so that fewer errors happen, and it sells that software to hardware makers who compete with one another. His route to the company ran through physics at the University of Pennsylvania and a doctorate at Harvard. Programme management at DARPA followed, and then a fellowship in the ion storage group at the National Institute of Standards and Technology in Boulder. The Boulder years produced the 2009 Nature paper on which the business rests. It showed that the right sequence of microwave pulses, chosen by feedback from the machine itself, could cut the errors in a trapped-ion memory by orders of magnitude without touching the hardware. That result matters commercially because it does not care which kind of qubit it is applied to. In a single announcement in September 2024 Q-CTRL said its Fire Opal software would run natively inside IBM Quantum services, Rigetti’s cloud service, Oxford Quantum…
