Quantum Computing Milestone in Finance: HSBC Test Shows 34% Improvement in Transaction Efficiency
```
A test conducted by HSBC in cooperation with IBM has achieved a milestone in the application of quantum computing in the financial sector. The results show that this emerging technology is expected to significantly improve trade execution efficiency, injecting new momentum into Wall Street’s exploration of the next frontier in computing power.
HSBC, the largest bank in Europe, said on Thursday that the company tested a quantum computing tool developed by IBM and found that it was 34% more efficient than traditional methods in predicting trade execution probability. This achievement is based on theoretical analysis of historical data from the European corporate bond market.
“This is by far our most tangible evidence of just how close we are to extracting value from quantum computing,” said Philip Intallura, Head of Quantum Technologies at HSBC Group. He added:
“We firmly believe we are at the forefront of a new field in financial services computing, rather than merely looking toward the distant future.”
Although these results currently remain at the theoretical level, they indicate that quantum computing could have a significant impact on trading, especially in over-the-counter (OTC) markets that lack central brokers.
Key Finding: Quantum Tools Significantly Improve Trading Prediction Efficiency
Quantum computing represents an entirely new branch of computing, its core advantage lies in leveraging the laws of quantum mechanics to process information. Jay Gambetta, Vice President of IBM Quantum, explained in a statement:
“It represents and processes information in a space that is broader and more dynamic than that accessible by classical systems.”
This capability comes from quantum bits (qubits), the fundamental building blocks of quantum machines, allowing computers to perform complex computations at speeds far beyond those of traditional computers.
Currently, tech giants are fiercely competing for leadership in the field of quantum computing. IBM is racing against competitors such as Google, aiming to produce an industrial-scale quantum computer by the end of this decade. Beyond the financial sector, quantum computing is believed to have the potential to drive breakthroughs in scientific research fields, including drug development.
The test conducted by HSBC and the IBM team was based on the analysis of more than 1 million quote requests between September 2023 and October 2024, involving over 5,000 bonds. The study aimed to verify the performance of quantum tools in predicting the probability of quote requests being executed.
While the 34% improvement in efficiency is remarkable, a published research report also cautiously noted that this conclusion was drawn from a specific historical data set. The report cautions that these findings “do not guarantee universality for other market environments or trading data sets.”
While quantum computing holds the potential to revolutionize efficiency in financial trading, it also introduces new risks. Experts are concerned that the advent of quantum computing will threaten currently widely used sensitive data encryption technologies, including encryption systems used internally by banks and other financial institutions.
