The Majorana 1

 

17 years of research has led to Microsoft creating a new material and architecture for quantum computing. Majorana 1, the first Quantum Processing Unit (QPU), is powered by a hardware-protected topological qubit, and could have a substantial impact on the financial services and fintech industries. Here’s how.

What is quantum computing?

Quantum computing is based on quantum mechanics. Units of information, otherwise known as qubits, can exist in multiple states at any one time. This, referred to as superposition, allows many combinations of zeros and ones to also be processed at the same time.

Qubits can run multidimensional quantum algorithms and handle far more complex quantum problems than the single binary process of a traditional computer.

What is topological quantum computing?

Topological quantum computing is a form of quantum computing that leverages anyons, quasiparticles that exhibit fractional statistics and do not interact in any specific order.

CalaHealth data scientist Alexander Li defines it as seeking: “to implement a more resilient qubit by utilizing non-Abelian forms of matter to store quantum information. In such a scheme, information is encoded not in the quasiparticles themselves, but in the manner in which they interact and are braided. Thus, this scheme is topological, meaning that only the macroscopic topological properties of the particles’ worldlines matter. This makes topological quantum computing more resistant to decoherence and noise issues which plague other qubit implementations.”

Microsoft’s Majorana 1

Microsoft is on track to build the world’s first fault-tolerant prototype (FTP) of a scalable quantum computer based on topological qubits. Chetan Nayak, technical fellow and corporate vice president of quantum hardware, Microsoft highlighted that all “of today’s announcements build on our team’s recent breakthrough: the world’s first topoconductor.

“This revolutionary class of materials enables us to create topological superconductivity, a new state of matter that previously existed only in theory. The advance stems from Microsoft’s innovations in the design and fabrication of gate-defined devices that combine indium arsenide (a semiconductor) and aluminum (a superconductor). When cooled to near absolute zero and tuned with magnetic fields, these devices form topological superconducting nanowires with Majorana Zero Modes (MZMs) at the wires’ ends.”

He continues: “For nearly a century, these quasiparticles existed only in textbooks. Now, we can create and control them on demand in our topoconductors. MZMs are the building blocks of our qubits, storing quantum information through ‘parity’—whether the wire contains an even or odd number of electrons.

“In conventional superconductors, electrons bind into Cooper pairs and move without resistance. Any unpaired electron can be detected because its presence requires extra energy. Our topoconductors are different: here, an unpaired electron is shared between a pair of MZMs, making it invisible to the environment. This unique property protects the quantum information.”

How will the Majorana 1 chip impact fintech?

Microsoft’s Majorana 1 chip launch marks a substantial step forward in quantum computing. Because the processor uses an architecture that is based on topological qubits, which are more stable and less susceptible to errors than traditional qubits, financial problems could potentially be resolved more accurately than ever before.

While quantum computing is in its early stages, technical hurdles such as qubit stability and error correction that once stood in the way of adoption, may no longer be an issue with topological quantum computing chips like the Majorana 1. Here’s how Microsoft’s new development could impact the fintech industry:

• Cross border payments

The Majorana 1 chip could optimise transaction processing and reduce the time it takes for cross-border payments or complex financial transactions to be completed. This would in turn, enhance enhance user experiences, particularly in high-frequency trading.

• Security and encryption

The Majorana 1 chip could support cryptography and enable more secure encryption that is unbreakable by classic computers. This could be a giant step forward for fintech firms that use encryption to prevent fraud or handle sensitive financial transactions and personal data.

• Financial modelling and risk analysis

The Majorana 1 chip can process vast amounts of data simultaneously and could change the way financial models are built. As a result, risk assessments will be more accurate and fintech firms that rely on predictive models to assess market conditions, evaluate risk, and optimise investment strategies, will be able to operate in a more efficient and precise manner.

• Portfolio management and optimisation

The Majorana 1 chip could enable more advanced algorithms to be applied to portfolio management, process more variables than classical systems, and in turn, smarter, more personalised investment portfolios. With this, fintech companies would be able to offer tailored financial products with better asset allocation strategies.

• Supply chain and operations

The Majorana 1 chip could be used to streamline supply chains and internal operations within financial organisations with complex backend systems. Quantum algorithms can be used to better resource allocation, improve scheduling, or predict demand for certain financial products.

 

A transition to quantum computing will require organisations to adapt their existing systems to integrate with quantum technologies, which could be costly and time-consuming. The new capabilities introduced by quantum computing will also raise questions about privacy, data protection, and regulation. Fintech companies may need to work closely with regulators to ensure compliance as they adopt quantum technology. The Majorana 1 chip could have a transformative impact on the fintech sector, particularly in areas like security, optimisation, and financial modelling.
