"While quantum computers don't yet pose an imminent threat to cybersecurity, it's crucial to stay ahead of the curve by examining the resilience of current encryption protocols," Vartiainen cautions.

Businesses gear up for the quantum era – time to rethink encryption

Quantum computing has rapidly evolved over recent years, captivating the business community with its enormous potential for accelerated computational power. This burgeoning technology promises to revolutionize a myriad of sectors while also raising critical questions about preparedness for potential cybersecurity threats. 

Juha Vartiainen, co-founder and Global Affairs Officer at IQM, Europe's preeminent quantum computing firm, is optimistic about the transformative potential of quantum technologies. Leading a team at the vanguard of quantum innovation, Vartiainen envisions quantum computers as complementary assets to existing computational frameworks. 

"Quantum computers shouldn't be viewed as replacements for classical computers, but rather as accelerators of computational prowess. They will soon be integral components in data centres, operating in conjunction with traditional computing systems," Vartiainen asserts. 

Although IQM's quantum systems are primarily deployed for educational and research purposes, the company foresees their commercial application in the near future. 

"Quantum computers are initially earmarked for academic and research applications, but it won't be long before they enter the commercial arena on a grand scale. Eventually, they could even be integrated into consumer services, accessible via mobile networks," he elaborates. 

Talent Shortage and Technological Barriers: Obstacles to Quantum Advancement 

Despite its enormous potential, the trajectory toward widespread quantum adoption is fraught with challenges. One significant hurdle is the extensive infrastructure required for cooling quantum systems. Current setups necessitate massive cooling units, heavy-duty wiring, and robust electronics racks. Yet Vartiainen identifies an even more pressing impediment—talent scarcity. 

"There's a global shortage of highly trained quantum engineers, particularly those with Ph.D. qualifications. The fight for talent is intense, and it's a battle that transcends borders. Prioritizing talent acquisition and well-being of these experts is essential for progress in this field," he notes. 

To promote expertise in the quantum field, IQM has, among other things, launched the open-for-all 'IQM Academy' online course, through which anyone can receive free training on the subject. In addition, in collaboration with other stakeholders, it organizes hackathons and superconducting quantum computer and tailored learning experiences for universities and research labs worldwide. 

Promising experiments in various industries 

Finland is among the global leaders in the quantum ecosystem, boasting numerous top-tier companies and research institutes.  

"While it's tempting to focus on the number of qubits, we should adopt a broader perspective. The U.S. might have a slight lead, with quantum firms already going public, and China is also a key player. However, the global landscape is hampered by the skills shortage. A concerted investment in university-level training is imperative for any country wishing to succeed in this domain," Vartiainen advises. 

Business sectors such as finance and automotive are already exploring the advantages of quantum computing.  

"In finance, quantum algorithms are being used for portfolio optimization. In the automotive industry, molecular simulations aid the development of enhanced battery materials. The hydrogen sector is also eyeing improvements in thin-film technologies," Vartiainen reveals. 

Preparing for the Post-Quantum Crypto 

The advent of quantum computing also presents unique challenges to cybersecurity. The computational might of these machines could potentially shatter existing encryption algorithms. Conversely, quantum computing introduces unbreakable encryption techniques governed by the laws of physics, thereby enhancing data security. 

"While quantum computers don't yet pose an imminent threat to cybersecurity, it's crucial to stay ahead of the curve by examining the resilience of current encryption protocols," Vartiainen cautions. "For instance, the U.S. government is transitioning to quantum-resistant encryption next year. Organizations with heightened security requirements should consider similar upgrades." 

As the business world gradually awakens to the quantum age, preparation is key. 

"Business leaders sometimes say that they’d prefer a two-year cushion to get ready for the quantum revolution. Well, I'm throwing the cushion their way – It's time to roll up the sleeves and, at the very least, task someone in the organization with investigating the immense possibilities that quantum computing presents," Vartiainen concludes.
