Quantum technology is quickly becoming a reality, and is on its way to widespread adoption. A 2024 survey by QuEra Computing found that 51% of quantum professionals believe that Quantum Computing’s rate of growth surpasses their projections, and 40% expect quantum machines to beat classical computers at simulation within five years. The Quantum Computing industry has a projected revenue forecast of USD 4.24 billion by 2030, making it vital for businesses to keep up with such developments.

Singapore is actively pursuing this future through initiatives like the HQCC (Hybrid Quantum Classical Computing Initiative), accelerating the arrival of practical quantum solutions. Local businesses and investors are already investing heavily in quantum development, both domestically and overseas in anticipation of the advent of quantum computers.
In order to maintain a competitive edge, business leaders should be following this lead, and prepare their organisations for early adoption. Industries that successfully harness Quantum Computing stand to gain a significant competitive advantage, and understanding its use cases will be crucial for engaging effectively with this transformative technology.

What is Quantum Computing?

Quantum Computing is a form of computing that uses qubits (quantum bits) rather than the binary bits of modern-day computers. Quantum technology allows qubits to represent both 0 and 1 simultaneously, allowing computers to explore multiple outcomes at once.

This gives quantum computers a massive increase in computational power, allowing them to excel at problems involving multiple variables or large simulation spaces. For example, they can simulate molecular structures more efficiently than traditional computers, by creating the entire space these molecules exist in.

Across multiple fields such as engineering, finance, and shipping, quantum algorithms are offering various new ways to solve complex problems.

Key Use Cases

Several industries are likely to be impacted by this emerging technology. Quantum Computing stands to immediately improve their systems and processes, resulting in decreased operational costs and improved overall efficiency.

Logistics Optimisation

Quantum Computing excels at processing vast combinations of variables simultaneously. This capability allows it to improve route optimisation by evaluating potential paths. Logistics-heavy industries like shipping, aviation, and e-commerce can use quantum algorithms to enhance their supply chain management. They gain faster decision-making tools that adjust to real-time changes in demand and delivery conditions.

Furthermore, this technology optimises resource allocation, reducing waste and lowering operational costs. Warehouses can improve efficiency by dynamically adjusting storage and retrieval procedures. Real-time dynamic scheduling, inventory management, and fleet management are all areas that can be powered by quantum technology. This can lead to lesser downtime, fewer delivery delays, and better customer service in the logistics sector.

Financial Modelling

Quantum Computing allows financial institutions and financial services to analyse large datasets more efficiently, enabling faster processing of complex financial data and improving accuracy over traditional methods. Predictions from experts state that when Quantum Computing hardware becomes widespread, it is likely to have 100,000 qubits at once. Formerly impossible problems could be solved in mere days or hours by leveraging this increased capability.

Another quantum advantage is its capability to simulate more varied market conditions. Currently, financial analysis looks at investment portfolios, projected prices, and risk assessments to simulate market conditions and predict potential outcomes. The use of quantum systems for such a purpose can allow for more variables to be calculated, aiding experts in pricing complex derivatives and assessing portfolio performance under different scenarios, resulting in quicker responses to market changes.

Chemical and Pharmaceutical Research

In the pharmaceutical research field, simulation of complex molecular structures is a key method of predicting how substances and chemicals react. However, this process is hampered by computational limits. On the other hand, Quantum Computing can enable highly accurate simulations of atomic and molecular interactions on a more reasonable timescale. This capability helps researchers better understand complex molecular structures that are difficult to model using classical computers.

In pharmaceutical research, this improvement can potentially speed up the discovery of new drugs, identify promising compounds, and reduce the need for extensive trial-and-error testing.

Safeguarding Businesses in a Quantum-based Future

Along with the benefits brought by quantum hardware, the shift towards this new technology creates risks that businesses need to address. The primary threat is quantum decryption, which threatens to negate current encryption methods used in cryptography. With its superior computational power, Quantum Computing is expected to result in easy decryption, placing businesses at risk of having their critical data exploited.

Industries most vulnerable include those that handle sensitive information, such as the government, financial services, and healthcare sectors. Government organisations handle sensitive data essential for national security. Financial services rely heavily on encrypted transactions to maintain integrity. Healthcare databases hold vast amounts of personal and clinical data. All three are at risk from breaches amplified by quantum decryption.

Fortunately, a countermeasure exists in the form of Quantum Key Distribution (QKD).

What is Quantum Key Distribution?

QKD is a quantum-safe encryption technology that provides secure communication via quantum mechanics. It makes use of cryptographic quantum keys and distributes them between the sender and receiver. Any eavesdropping attempt can be immediately detected, preventing unauthorised access. This technology creates a new layer of security resistant to quantum attacks, safeguarding critical communications.

Through the use of this quantum cryptography technology, SPTel can protect the critical data of vulnerable organisations and industries. Our expertise allows us to stand at the forefront of QKD deployment, and take steps towards creating a Quantum-Safe Nation alongside numerous world-class industry partners.

Creating a Quantum-Safe Nation with SPTel

To build a Quantum-Safe Nation, SPTel, together with partner SpeQtral, were appointed by IMDA as part of the National Quantum-Safe Network Plus (NQSN+) project. Today, this appointment has resulted in a successful partnership with the Monetary Authority of Singapore (MAS) and several leading financial institutions in a Memorandum of Understanding, to establish a quantum security initiative within the finance sector.

This has led to two major wins for SPTel in the recent Asian Telecom Awards 2025 for Network & Security Integration of the Year and Technology Innovation of the Year for delivering Singapore’s first Quantum-Safe Network. Our advancements in this field have empowered businesses to defend against quantum threats via Quantum Key Distribution.

As quantum cybersecurity becomes essential for future-proofing organisations against the evolving threat landscape brought by Quantum Computing, SPTel can help business leaders prepare for this eventuality. Companies can seamlessly integrate quantum-safe data transfer into their operations without overhauling their existing IT infrastructure by leveraging SPTel’s quantum-safe services, and ensure that critical data remains secure against emerging threats.

Building Quantum Resilience with Quantum Key Distribution

Quantum Computing is a rapidly emerging reality for various industries, and has the power to revolutionise workflows. As Singapore continues to invest in innovation, early adopters need to safeguard themselves against undue risks by making use of long-term precautions and investments.

SPTel and partner SpeQtral’s expertise in the quantum field provides organisations a proactive path to quantum-resilient cybersecurity, safeguarding today’s information against tomorrow’s quantum challenges. Learn more about our Quantum Safe Network for Singapore businesses today.
