HOW DOES IT WORK?

Quantum computing is a revolutionary technology that harnesses the laws of quantum mechanics to perform complex calculations that traditional computers cannot. While it is a relatively new field, it holds tremendous potential for driving digital transformation. Unlike classical computing, which uses bits to represent information as either 0 or 1, quantum computing relies on qubits that can simultaneously represent both 0 and 1 states. Since quantum computing relies on quantum qubits to represent information, this allows for faster processing and greater computing power. There are several approaches to building a quantum computer, but the two most popular are using superconducting qubits and trapped atomic qubits, such as trapped ions and neutral atoms.
Superconducting qubits mimic atomic systems using artificial atoms which is one of the most promising approaches to quantum computing. They rely on the principles of superconductivity, which is the ability of certain materials to conduct electricity with zero resistance at very low temperatures. Superconducting qubits are currently the most widely used type of qubit in quantum computing research and development.
Superconducting qubits work by manipulating the state of a superconducting circuit. These circuits consist of loops of wire made from superconducting material, which are interrupted by one or more tiny electronic components that allow supercurrents to flow through them, creating a unique quantum state. One of the key advantages of superconducting qubits is their relative ease of fabrication. Superconducting circuits can be manufactured using existing semiconductor fabrication techniques, which makes them more accessible and easier to scale than other types of qubits. Another advantage of superconducting qubits is their long coherence times, the length of time that a qubit can maintain its quantum state before being disturbed by external factors. 
There are several examples of how superconducting qubits are being used in quantum computing research and development. For example, IBM has developed a 433-qubit Osprey quantum processor based on superconducting qubits, which has been used to perform calculations that are impossible for classical computers to solve. Another example is Google's recent claim of achieving quantum supremacy, demonstrating that their superconducting qubits can solve a specific problem faster than the fastest supercomputer in the world. 
Another promising approach to quantum computing is trapped atomic qubits that relies on the principles of quantum mechanics to manipulate the state of individual atoms. Trapped atomic qubits use lasers to trap and manipulate individual atoms, which are then used to perform quantum computations.

Trapped atomic qubits work by using lasers to trap individual atoms in a vacuum chamber. The atoms are then cooled to near absolute zero, which allows them to be manipulated with high precision. The state of the atoms can be manipulated using lasers, which allows researchers to perform calculations and create quantum circuits.
Similar to superconducting qubits, trapped atomic qubits are able to achieve long coherence times, which again is the length of time that a qubit can maintain its quantum state before being disturbed by external factors. Long coherence times, makes them more suitable for practical applications than other types of qubits. Another advantage of trapped atomic qubits is their scalability. Individual atoms can be manipulated and controlled with high precision, which makes them well-suited for building larger-scale quantum computing systems. This scalability is a significant advantage over other types of qubits that are more difficult to scale.
Trapped atomic qubits is at the forefront of quantum computing research and development, with several notable examples. One breakthrough, outlined in an April 2021 article published in Nature by Winfried Hensinger, demonstrated that trapped atomic ions can be used to realize quantum gates with the lowest quantum-computation errors of any hardware platform. In addition, Infleqtion/Cold Quanta was awarded the DARPA ONISQ program in November 2020, which requires the demonstration of a system with over 1000 qubits running an application. Additionally, IonQ leverages trapped atomic qubits to perform calculations and has attracted attention from major companies, including Goldman Sachs and Amazon Web Services, for the development of quantum algorithms.
 

WHAT DOES QUANTUM COMPUTING HAVE THE PROMISE OF?

Today's qubit platforms are akin to the vacuum tube creation in the early 1930s in that companies and researchers are exploring the potential uses of these qubits and discovering what they can do and what they can't.
As the field of quantum computing advances, its potential to revolutionize various industries, including finance, healthcare, and logistics, is becoming increasingly apparent. By leveraging the unique properties of qubits, quantum computing could enable the optimization of complex financial portfolios, the development of new drugs, and the optimization of supply chain logistics, among other applications. In the context of digital transformation, quantum computing offers new possibilities for enhancing operational efficiency, improving decision-making, and driving innovation.
However, the promise of quantum computing is accompanied by significant challenges that must be addressed before it can fully realize its potential. One major challenge is the inherent fragility of qubits, which can lead to errors and instability during computations. To mitigate this issue, error correction techniques are needed to maintain the reliability and accuracy of quantum computing systems.
Another major challenge is the potential threat to existing encryption methods, which rely on the difficulty of factoring large numbers. Quantum computing's ability to perform certain calculations exponentially faster than classical computers could render some encryption methods vulnerable to attack. As a result, new encryption techniques that can withstand quantum computing-based attacks will need to be developed.
Despite these challenges, the potential benefits of quantum computing are too significant to ignore. With careful consideration of the challenges and investments in research and development, quantum computing has the potential to transform industries and drive the next wave of digital transformation.
