You’ve no doubt heard of quantum computing at this juncture. And you know it might eventually impact your job in some way—but how? Let’s explore.

First things first: quantum computing isn’t an easy concept to explain. Classical computing relies on bits (which can be either a 1 or 0), and classical computations involve a single input, algorithm, and output. Contrast that with quantum computing, which relies on “qubits,” which exist not only as ones and zeros but in a “superposition” state in-between; in theory, that allows quantum computers to analyze multiple solutions and outputs simultaneously.

For example, while a decryption program running on a classical computer might need years to churn systematically through all possible passwords (absent some handy time-saving algorithms), a quantum computer could try all possible passwords simultaneously, reducing the unlocking time to seconds. Quantum computing could also benefit everything from the development of new medicines to optimizing delivery routes.

No wonder Microsoft, Google, IBM, and other companies are spending untold millions on quantum-computing research, hoping for a breakthrough that will make them a leader in this nascent industry.

Why Should You Care?

Although quantum computing isn't mainstream, it’s also much more than just a theoretical endeavor; companies everywhere are exploring its implications. Financial institutions are investigating its potential for portfolio optimization and fraud detection. Pharmaceutical companies are leveraging it for faster drug discovery. And tech giants like IBM, Google, and Microsoft are racing to make quantum computing more accessible.

For tech professionals, this means that industries you work in—or aspire to work in—might soon integrate quantum computing solutions. Having foundational knowledge could position you as a valuable asset in navigating these changes, including:

Cybersecurity: One of the most talked-about impacts of quantum computing is its potential to break widely used encryption algorithms, such as RSA and ECC. Post-quantum cryptography is already a hot topic, and professionals with knowledge in this area are in high demand. Whether you work in cybersecurity or just build software, you’ll need to understand quantum computing’s impact on cyber-threats at some point. 

Generalized Tech: Technology careers often demand continuous learning, and staying ahead of emerging trends is essential for long-term growth. Just as cloud computing, machine learning, and blockchain became critical knowledge areas over the past two decades, quantum computing is set to become a sought-after skill. Knowing the principles now will help when, say, AWS or Azure roll out a robust cloud-based quantum computing option on some future date.

Start Learning Quantum Computing

Quantum computing might seem intimidating, but learning its basics is more accessible than ever. Here's how to get started:

Grasp the Fundamentals

  • Learn the very basics of quantum mechanics, such as superposition and entanglement. You don’t need a Ph.D. in physics; many resources simplify these concepts for tech professionals. For example, Quantum Country is a fun, somewhat quirky intro to quantum.
