Technology is advancing at a rapid pace, and it is a challenge for everyone to keep up. Among them, SMEs must also actively prepare themselves to incorporate it into their business, especially if it benefits them in their particular case.

One of the latest technological advances is quantum technology, which consists of adopting the principles of quantum physics to create new tools and improve existing processes.

When this knowledge is applied to the business world, several benefits can be obtained, such as increased efficiency and agility in data analysis, increased accuracy of calculations, more accessible information, more accurate predictive modelling, improved security and protection of company data, and so on. The key for an SME that wants to adopt quantum technology is its readiness and willingness to use these new tools, as this simplifies the transition to this new methodology and increases its chances of success in different areas.

With respect to the use cases of quantum computing, four are distinguished:

• Optimisation of operations, such as calculating the best route for shipping products.
• Scenario prediction through the use of Quantum Machine Learning. For example, an SME dedicated to e-commerce can use it to predict the purchasing behaviour of its customers.
• The simulation of complex systems to study the behaviour of new designs incorporated by means of Quantum simulation. For example, it would be possible to evaluate the properties of building materials without the possession of the raw materials.
• The reinforcement of cybersecurity, through techniques such as quantum cryptography, framed within the area of Quantum cybersecurity. With this, it would be possible, for example, to encrypt the data of a transaction to prevent it from being traced.

Due to the complexity of this technology, its implementation can be challenging at first sight. It is therefore advisable to have a roadmap to increase the likelihood of success, which should always consider the following aspects:

1. Identify areas for improvement in the company.
2. Select the right tool according to the needs of the company.
3. Start by testing systems that combine the principles of quantum computing with the infrastructure of classical computing.
4. Prepare the staff on this technology.
5. Adopt a new technology-friendly organisational culture, through a diagnostic analysis and risk analysis.
6. Seek out partners or institutions that offer resources and expertise in the field, as well as help with a successful transition.

In addition to these tips, it is essential to know how to set up quantum computing within an SME, which includes reviewing the availability and compatibility of existing resources with quantum technology, performing various tests to define the best resolution model, and verifying the legal regulations concerning the use of quantum technology.

Due to its complexity, this new technology poses certain challenges, such as the constant evolution of the technology, the inexperience of human staff, and the high cost of implementation in some cases.
