Quantum computing is expected to be the new technology, fully integrated with the financial sector within five to ten years. This form of computer, also known as supercomputers, are capable of highly advanced processing power that takes in massive amounts of data to solve a problem in a fraction of the time it would for the best traditional computer on the market to resolve.
Traditional Computer vs. Quantum Computing
A typical computer today stores information in the form of bits. These are represented in the binary language (0s and 1s). In quantum computing, the bits are known as Qubits and will take on the processing of similar input but rather than break it down to 0s and 1s will break the data down significantly greater where the possibilities of computational speed can be almost immeasurable.
Quantum Computing in Banking
Let’s examine personal encryption in banking for example. Using a security format called RSA-2048, traditional computers would be able to decrypt the security algorithm in about 1,034 steps. With our best computers on the market, even with a processor capable of performing a trillion calculations per second, these steps translate to 317 billion years to break the secure code. While it is possible, it is not practical for a cyber-criminal to make it worthwhile.
A quantum computer, on the other hand, would be able to resolve this problem in about 107 steps. With a basic quantum computer running at one million calculations per second, this translates to ten seconds to resolve the problem.
While this example centered on breaking complex security, many other use cases can emerge from the use of quantum computing.
Trade Transaction Settlements
Barclays bank researchers have been working on a proof of concept regarding the transaction settlement process. As settlements can only be worked on a transaction-by-transaction basis, they can easily queue up only to be released in batches. When a processing window opens, as many trades as possible are settled.
Complex by their very nature, Traders can end up tapping into funds prior to the transaction being cleared. They will only be settled if the funds are available or if a collateral credit facility was arranged.
As you could probably handle a small number of trades in your head, you would need to rely on a computer after about 10-20 transactions. The same can be described for our current computational power in that it is now nearing the point where it will need more and more time to resolve hundreds of trades at a time.
With quantum computing using a seven-qubit system, it would be able to run a greater amount of complex trades in the same time it would for a traditional system to complete the trades. It would take the equivalent of about two hundred traditional computers to match the speed.
Simulating a Future Product Valuation
Researchers at JP Morgan were working on a concept that simulates the future value of a financial product. The team is testing quantum computers to perform complex intensive pricing calculations that normally take traditional computer hours to complete. This is a problem as each year greater complexity is added via newer algorithms, getting to the point where it is nearing an impossibility to calculate in a practical sense.
The research team has discovered that using quantum computing resulted in finding a resolution to the problem in mere seconds.
Banks are working on successful tests today with quantum computing to resolve extreme resource-intensive calculations for financial problem scenarios. Everything from trading, fraud, AML, etc. this is a technology not to be overlooked.
According to Deltec Bank, Bahamas – “Quantum Computing will have positive impacts on portfolio optimization, risk analysis, asset pricing, and trading strategies is just the tip of the iceberg of what this technology could provide.”
