Quantum computing is poised to transform the way companies solve business problems. The technology needed to power this revolution is becoming a reality, with large developers like IBM making excellent progress toward building quantum-centric supercomputers. But while the technological barrier to deploying quantum is falling away, another obstacle remains: The lack of quantum skills in the labor market.

Last year, Classiq commissioned a survey of over 500 professionals familiar with quantum technology, which highlighted a range of possible benefits that quantum computing will unlock, including cost savings, new revenue streams and competitive advantages for companies that successfully deploy the technology. But the survey also highlighted that the shortage of qualified engineers and scientists who can program quantum computers remains one of the biggest barriers to increased quantum deployments.

This skills gap will not only prevent companies from leveraging the power of quantum computing but also lead to expensive competition for talent as businesses try to recruit the few quantum professionals available in the workforce. Why has this skills gap grown, and what can companies do about it?

Coding for the Quantum Computing Era

First, we need to understand what skills are missing that are contributing to a skills gap, as some readers may ask why existing programmers and computer engineers cannot meet this demand. Besides lacking the purely technical skills needed to code for quantum computing, such as creating quantum circuits and software, there is also a knowledge gap around how to solve business problems using a quantum computer.

For instance, while many programmers trained in classical computing could figure out a way to design a program for portfolio optimization, they likely have no idea how to do the same using a quantum computer. They are unlikely to know where to start, how to check their results or even how to run their code on a quantum device.

Coding for quantum computers is also more complicated than for classical computing. As each “qubit” can be one and zero simultaneously instead of either/or, writing the quantum code is more complex. Developers need to understand quantum concepts such as superpositions, so working in quantum requires new ways of thinking about problems and necessitates new ways of working.

This last issue is compounded by a technology gap, as quantum programming has not been abstracted away as it has for classical programming – it is mostly still at the assembly language level. At this level, writing a few dozen lines of quantum programming is achievable but time-consuming, so creating complex quantum programs of hundreds or thousands of lines of code is almost impossible.

Solving the Skills Gap

The first instinct for companies wishing to leverage quantum technology is to hire their way out of this problem, but there are simply not enough Ph.D.-trained quantum experts in the market, and there is likely to be stiff competition for the few quantum-trained graduates coming out of university. Given the shortage, companies must instead consider how to train and upskill their staff.

Convincing existing staff to take part in this training should not be an issue. Engineers and programmers are keen to learn – nearly 95% of respondents to our survey said they would like to be trained in quantum. Why is there such high demand? Not only is this new technology exciting, but many workers may hope to future-proof their jobs or increase their earning potential through quantum skills.

Upskilling your workforce does not have to be expensive. There is already a wide range of open source material, such as the Qiskit development kit, designed to help people explore this new technology. For companies, a straightforward solution is to give their engineers the time and space to learn about quantum for themselves. Simply giving your existing coders permission and resources to learn about this technology and how it can benefit your business could prove to be a profitable long-term investment.

The added advantage of upskilling your staff, rather than recruiting quantum Ph.D. graduates, is your existing workforce understands the sorts of problems your business needs to solve.

Plus, new products are emerging that can help solve the technology gap and make it easier to code for the quantum era. Sophisticated low-code software can abstract away some of the complexity involved in writing quantum coding, which in turn will speed up the process of learning.

But upskilling is only one thing to consider. Companies also need to invest in the resources and infrastructure around their emerging quantum talent. They need to build a team, identify use cases that can benefit from quantum technology and locate the right vendors and cloud providers that will allow them to test and simulate their quantum programs.

The quantum revolution remains several years away, but companies need to make sure they have the skills and infrastructure ready to take advantage of this technology or risk being left behind by quantum-prepared competitors.
