How Do Quantum Computers Work?

​​The true strength of quantum computing lies in its ability to navigate vast quantities of possibilities, sifting through them to extract potential solutions to intricate challenges.

At the core of this technology are qubits, which encode information in a quantum state that transcends the binary limitations of 0 and 1, encompassing a multidimensional spectrum.

What are qubits made of in quantum systems? The composition of qubits varies depending on the architecture, with specific requirements for optimal functionality. Cold temperatures are often necessary. Qubits can consist of trapped ions, photons, artificial or natural atoms, or even quasiparticles.

Operating on the principles of quantum mechanics, these computers introduce a new lexicon of terms requiring comprehension.

Let’s explore the three key principles in more detail below:


Just as classical physics allows adding waves, quantum states can be combined, resulting in new valid ones. Moreover, any quantum state can be expressed as a sum of multiple distinct states. 

This remarkable feature, known as superposition, grants quantum computers inherent parallelism. Harnessing this parallelism enables these machines to execute millions of operations simultaneously.


Quantum entanglement occurs when two systems become intricately connected, regardless of their physical distance. Entanglement is remarkable because acquiring information about one particle instantly reveals details about the other, regardless of their spatial separation.

This unique relationship forms the basis for quantum algorithms designed to tackle complex problems. Moreover, the addition of qubits results in an exponential surge in computational capabilities.


Decoherence arises when qubits lose their quantum behavior due to external factors like vibrations or temperature fluctuations. Such disturbances can cause qubits to lose their superposition state and introduce errors in computations.

To mitigate this issue, protective measures are necessary, such as utilizing insulation, supercooled refrigerators, and vacuum chambers to shield qubits from external interference.

Quantum Computing vs. Classical Computing: What is the Difference?

Classical and quantum computing differ in their building blocks. Traditional computers use binary digits (0s and 1s), while quantum computers use qubits. This makes quantum computers highly efficient for complex AI applications, as they are less prone to errors than classical computers.

Quantum computing enhances classical computing by improving specialized functions and offering greater accuracy and efficiency. They process data faster, enabling faster learning and improvement for AI systems. Quantum entanglement optimizes correlations between variables.

Quantum computers excel at solving complex optimization problems, leading to more powerful and intelligent AI systems beyond classical physics laws. They benefit various AI applications like planning and scheduling.

They accelerate AI architecture development, performing calculations and creating new algorithms that classical computers can’t. They provide solutions to unsolvable problems using classical methods.

Quantum computers enable faster learning and robust simulations for real-world scenarios without catastrophic forgetting, ensuring lifelong learning without losing previous knowledge.

Quantum computers also provide data security and can counter cybercrime through parallel processing. Their ability to exist in multiple states simultaneously aids in discovering superior algorithms.

Quantum computing boosts the potential of AI by amplifying its velocity, efficacy, and precision. It transcends the limitations imposed on traditional computers by utilizing qubits and capitalizing on non-linear operations.

This remarkable advancement empowers quantum computing to find applications across diverse AI use cases. Sectors like maritime logistics, semiconductors, electric vehicles, luminescence, and power have already started reaping the rewards of quantum computing’s exceptional problem-solving prowess.

Let’s explore the impact of quantum computing on different industries and the transformative effects it brings to AI-driven processes.

Medical Care

Hospitals often form a medical board of specialists from diverse fields to address complex conditions in critically ill patients.

However, this traditional approach is time-consuming and hampers decision-making. Quantum computing offers a solution.

By inputting various possibilities and relevant historical data, healthcare professionals can leverage quantum computing to evaluate treatment effectiveness and receive optimal recommendations swiftly. 

The quantum advantage allows providers to acquire valuable insights in a considerably reduced time frame.

Machine Learning (ML)

Machine learning (ML) relies on computers’ ability to acquire knowledge from data and generate or recognize patterns, similar to how the human brain functions.

However, the effectiveness of machine learning can be hindered by subpar data quality and the sluggish availability of data. This is where quantum computing comes into play, offering the potential to rapidly process large volumes of data rapidly, thus granting machine learning the same advantage.

A notable example of this potential is a collaborative project, “Quantum Advantage in Learning from Experiments,” involving scientists from renowned institutions like Caltech, Harvard, Berkeley, and Microsoft.

Published findings reveal the exceptional performance of their quantum computer, Sycamore, compared to classical learning agents, demonstrating exponential superiority across a diverse range of tasks, highlighting the remarkable capabilities of quantum learning agents. 

Cryptography and Security

Quantum computing can make it harder for unauthorized parties to breach data using qubits to calculate all possible breach methods, allowing for stronger security measures.

However, critics argue that this very power of quantum computing could be leveraged by hackers to quickly devise strategies for infiltrating servers containing sensitive data, potentially compromising existing security measures.

That is why the development of quantum-resistant cryptography is a main focus of the National Institute of Standards and Technology (NIST). Through its Post-Quantum Cryptography Standardization Program, NIST aims to create a stronger cryptographic system that can withstand quantum attacks, surpassing the current widely adopted methods.

This pursuit of enhanced security measures is closely tied to the geopolitical landscape, as it fuels the competition between the United States and China in the race to advance quantum technology.

Financial Application

Quantum computing’s integration promises to enhance market predictions and risk management. 

Multiverse Computing, Pasqal, and Crédit Agricole recently completed a 1.5-year proof-of-concept study on quantum computing’s potential in financial product valuation and credit risk assessment.

Notable advancements were achieved, reducing computing time and memory usage. Using a mere 50-qubit quantum processor, accurate results comparable to conventional methods were obtained, paving the way for real-world applications, specifically in derivatives valuation.

Anticipated advancements are on the horizon as a 300-qubit quantum processor is expected to become accessible in 2024. This breakthrough research marks the introduction of the inaugural quantum-enhanced machine learning algorithm designed specifically for forecasting credit rating downgrades.

Natural Language Processing (NLP)

Quantum computing can enhance natural language processing (NLP) and speech recognition, leading to more efficient and accurate communication. In that sense, quantum NLP (QNLP) aims to surpass the capabilities of traditional NLP by translating language into coded circuits processed by quantum computers.

Advancements in quantum computing enable QNLP to deliver enhanced effectiveness, faster processing, reduced power consumption, and a smaller environmental footprint. QNLP leverages quantum computing to accelerate the training process for data-intensive AI models, resulting in reduced training time.

For instance, Quantinuum (a company that integrates software and hardware solutions for quantum computing), with expertise in QNLP, recently collaborated with UCL and the BBC to explore the commercial potential in content discovery and archive retrieval. 

Through the transformation of sentences into logical formats and the use of string diagrams, QNLP simplifies NLP design on quantum hardware. These encoded quantum circuits can be optimized for machine learning applications.
